网络同步播放器、配置编辑器使用说明一.系统需要安装vcredist2010.exe,ffdshow_rev3555_20100901.exe,dotnetfx35.exe(win7系统可以不装)二.功能控制程序会收到“*p*”的心跳包,注意筛选。
此心跳包用于保持播放客户端与控制器直接的连接。
各个程序均无启动顺序要求,可随意启动。
但只有当所有播放客户端都正常启动运行以后才会接收响应各种指令。
在设置好启动播放视频以后,即使Flash控制程序不启动,客户端仍然可以自动播放,当Flash启动以后,主控程序会自动连接,此时flash可以随时发送指令控制播放。
主控程序也可以播放音频文件,支持格式为wav、mp3。
便于在运行主控程序的电脑上输出音频。
是否播放可在配置文件里设置。
PlayerController.exe 主控程序文件接收控制指令,可来自于触摸屏交互控制界面,UMPC或PDA控制程序等(服务端、客户端均可,配置文件里有设置),凡是通过Socket发送的指定格式的指令都能响应,与发送指令的控制程序形式无关。
控制客户端播放器响应指令。
可放在系统内任意一台电脑上。
当播放类指令(play, repeat,loop)执行完毕会返回给控制程序一条信息“Playfinished|x”, x表示播放完成的视频编号。
SocketPlayer.exe 客户端播放程序文件连接输出显示设备的电脑上运行的视频播放程序,由主控程序控制。
每个都具有音频输出能力,取决于播放视频文件是否包含音轨,是否连接声音输出设备。
如果需要可以和主控程序放在同一电脑上,作为视频监视和音频输出使用,此时注意设置窗口大小和位置。
config.xml 配置文件设置相关配置信息。
主控程序和客户端播放程序都使用此文件。
DelayExec.exe 顺序延时启动工具(可选)可按指定顺序和延时启动指定的程序。
四.播放指令说明1.播放:play|x|yx:数字,指定需要的播放视频编号,编号是在配置文件里指定视频文件的顺序,从1为起始。

VS1053的应用
VS1053的应用VS1053本身是一款非常强大的MP3解码芯片,然而大多是人实践上才用了它很小一部份功能。
我也是第一次使用VS1053,所以也只用了它非常少的功能。
1. 最常见的方法就是,通过MCU控制VS1053进行解码。
用这中方法是最为简单的,只要正确使用VS1053的命令就可以实现。
当然这样可以快速使用VS1053,是入门的最好方法,但是成本比较高。
2. 直接使用VS1053进行控制,这样就节约了一块MCU。
不过需要应用VSIDE平台,所以使用起来相当比较麻烦。
本人就讲讲使用第一种方法的应用,等以后利用第二种方法进行开发时,在和大家一起学习。
VS1053的应用其实非常简单,基本的步骤如下:1. 编写好SPI总线驱动代码;2. 编写好VS1053初始化代码;3. 编写正弦波测试代码;4. 内存测试代码。
完成以上几个步骤后就可以进行MP3解码了。

MP3播放器实验
它使用的 IO 为:
VS1053 的 SPI 支持两种模式: 1, VS1002 有效模式 (即新模式) 。 2, VS1001 兼容模式。这里我们仅介绍 VS1002 有效模式(此模式也是 VS1053 的默认模 式) 。 从原理图中,我们看出 VS1053 跟单片机相连的引脚主要有 7 根,他们是: 1) VS_MISO:SPI 输入线 2) VS_MOSI:SPI 输出线 3) VS_SCK:SPI 时钟线 4) VS_XCS:器件片选 5) VS_XDCS:数据片选和字节同步 6) VS_DREQ: 数据请求, 输入总线。 这个信号引脚是用来反馈 VS1053 的 2048 字节 FIFO 是否可以接受数据。如果它为高电平,则 VS1053 可以接收最少 32 字节的 SDI 数据或者接受 SCI 命令。 当流缓冲区太 满和 SCI 命令正在执行的期间,DREQ 会转换到低电平,此时应该 停止想 VS1053 发送新数据和命令。 7) VS_RST:复位端 31.2 VS1053 的操作 VS1053 通信支持 SPI 协议,所以我们使用 STM32 的硬件 SPI 发送接收数据 就可以了, 开发板上面使用的是 STM32 的硬件 SPI1, 具体操作跟之前介绍的 SPI 操作时一样的,这么我们就不详细介绍了。 1. SCI 串行命令写操作 此串行命令接口 SCI 的串行总线协议包括:一个指令字节、一个地址字节和 一个 16 位的数据字,也就是 4 个字节。

device in the VLSI Solution’s VS10XX audio codec family in that it allows for the user to encodefiles into the highly efficient Ogg Vorbis format.This makes it possible for the user to build a device that can record high-quality stereo sound while retaining moderatefile sizes.This document is an instruction manual on how to use the VS1053b Ogg Vorbis encoder application as well as an introduction to the Ogg Vorbis format itself.Chapter2describes how to load and run different Ogg Vorbis profiles on a VS1053b.It also discusses recording levels and recording level meters.Chapter3briefly introduces the Ogg Vorbis format.It also has some suggestions on how to encode data to Ogg Vorbis format as efficiently as possible on a PC.If you are unfamiliar with the Ogg Vorbis format,please read this chapterfirst.Chapter4tells how to load a plugin code to a VS10XX chip.Chapter5describes how a streaming VS1053b system can be built.The document version history is provided in Chapter6.Finally,Chapter7contains VLSI Solution’s contact information.2Using the Ogg Vorbis EncoderThe VS1053b Ogg Vorbis Encoder application is provided as a plugin in the same package as this document,downloadable athttp://www.vlsi.fi/en/support/software/vs10xxapplications.html.Before loading the application into your VS1053b,select one of the profiles shown below.2.1Limitations and Requirements•Maximum SPI(SCI)clock speed is3.5Mbit/s.If a higher speed is used,there may be occasional data read errors.2.2Ogg Vorbis Encoder ProfilesThere are45different Ogg Vorbis profiles available.They are divided intofive groups, depending on their samplerate and number of channels.2.2.1Profile GroupsThefive profile groups are presented below.As a comparison,bitratefigures for IMA

specifications.4Comparison bitrate for a4-bit IMA ADPCMfile with the same specifications.2.2.2Profile Quality SettingsEach of the low-sample-rate profile groups has eleven quality profiles,numbered from00 to10.The high-sample-rate profile groups have six quality profiles from00to05.This chapter presents thefive profile groups and gives estimates of typical bitrates that can be obtained with the profile.In general,quality setting05is designed to be a typical value that gives good quality for the application.Qualities00and01are for emergency use only when there just isn’t storage space for better quality settings.High qualities,starting from07or08, are intended for transparent sound quality,the intent being that compression cannot be heard anymore even under stringent circumstances.The“Voice”ProfilesThe“Voice”profiles are intended for speech applications.VoiceProfile number0001020304050607080910Typical kbit/s68101113152024273033The“Wideband Voice”Profiles“Wideband

altered during recording.SCI AICTRL0records the maximum absolute value of the signal.The maximum value of this linear register is0x7FFF in mono mode,or0x7F7F in stereo mode.For more information on how to use this register,see Chapter2.4.1.SCI AICTRL0is updated once for every Vorbis block,i.e.10...170times per second with the current profiles.SCI AICTRL1controls linear recording gain.1024is equal to digital gain1(recom-mended for best quality),2048is equal to digital gain2,and so on.If the user wants to use automatic gain control(AGC),SCI AICTRL1should be set to0.Speech applica-tions are often better offusing some AGC,as this helps to get relatively uniform speech loudness in recordings.SCI AICTRL2controls the maximum AGC gain if SCI AICTRL1is set to0.This limits amplification of noise when there is no signal.For more information on recording levels, see Chapter2.4.SCI AICTRL3offers run-time controls,channel selection for mono input,the maximum number of samples that are allowed in one Ogg frame with4096sample granularity,and the next unread byte,if any.Normally0(no limit)is a good value for granularity,but streaming applications often have maximum delay considerations,thus making limiting necessary.Note that limiting frame size isn’t entirely accurate,so always select a maxi-mum frame size slightly lower than your absolute upper delay limit.Example:your samplerate is44100Hz and you want frame output at least every500ms. Then you’ll need samples at22100sample intervals.Round this downwards to the closest 4096multiple,and you’ll get16384samples,so you’ll write0x40to SCI AICTRL3.The bitrate penalty of this example is≈0.5kbit/s.For this to work your reads must be byte aligned as explained in Chapter2.3.3.2.3.2Loading and Starting the CodeTo load and start the VS1053b Ogg Vorbis Encoder,do the following steps:1.If you have been doing ADPCM recording,clear bit SM ADPCM from registerSCI MODE(0).2.Set the VS1053b clock to the highest value just below55.3MHz.Example:if theexternal clock is12.288MHz,this can be done by setting the clock to4.5X,or55.296MHz by writing0xC000to register SCI CLOCKF(3).If you use anotherinput clock,adjust SCI CLOCKF accordingly.Examples:Value for12MHz is0xC3e8,12.288MHz is0xC000,13MHz is0xA4E2.3.Set SCI BASS(2)to0.4.Disable any potential user application by setting SCI AIADDR(10)to0.5.Disable all interrupts except the SCI interrupt by writing0x2to VS1053’s in-ternal register VS1053INT ENABLE.This is done byfirst writing0xC01A to SCI WRAMADDR(7),then0x2to SCI WRAM(6).6.Load the plugin profile you intend to run(Chapter4).Note that you will have toredo this each time you want to activate recording.7.Set bit SM ADPCM(12)in register SCI MODE(0)to1.At the same time,youcan also select LINE input instead of MIC input by setting bit SM LINE1(14)to1.If you want to use the VU meter in stereo mode,set also bit SM LAYER12(1)to1.Do not set SM RESET(2)at the same time!8.Set recording level control registers SCI AICTRL1(13)and SCI AICTRL2(14).Typical good values for conservative AGC are0and4096,respectively.For a HiFi application,recommended values are1024and0,respectively.9.If you want to use a VU meter,write0x8000to SCI AICTRL0(12)if using a monoprofile or0x8080is using a stereo profile.10.Set a proper value(often0)to SCI AICTRL3(15).11.Activate the encoder by writing0x34to register SCI AIADDR(10).12.Wait until DREQ pin is high before reading any data.2.3.3Reading Ogg Vorbis DataAfter Ogg Vorbis recording has been activated,registers SCI HDAT0and SCI HDAT1 have new functions.The Ogg Vorbis bitstream buffer size is409616-bit words,or8KiB.Thefill status of the buffer can be read from SCI HDAT1.If SCI HDAT1is greater than0,you can read that many16-bit words from SCI HDAT0.If data is not read fast enough from SCI HDAT0,the buffer overflows and returns to empty state.A data overflow will result in an incorrectfile that may be undecodable. However,because of the large size of the bitstream buffer and the relatively slow bitrates of Ogg Vorbis,this situation should be easy to avoid.Ogg frames are byte aligned.Because of the16-bit SCI interface this may be a problem for streaming applications where it is important to forward any Ogg frame as soon as possible:the latest frame may pend upon its last byte.If transferring data with a low delay is important,you can read whether there is one extra data byte by reading SCI AICTRL3twice in a row.The result of the latter read will contain the correct data: if bit2is1,then bits15:8contain the odd byte.After reading the odd byte successfully, discard bits15:8of the next read from SCI HDAT0because they contain the same data. (NOTE:if you don’t stream or don’t need the shortest possible delay,you can ignore this paragraph!)If you are having trouble with receiving data,notice that all Ogg Vorbisfiles always begin with the following4bytes:0x4f0x670x670x53(the string“OggS”).If you get0x67 0x4f0x530x67(“gOSg”)instead,you are storing the least and most significant byte in the16-bit data words incorrectly.If you get0x000x000x670x53,you have read data from SCI HDAT0too soon after starting the application.2.3.4Reading Additional Data while Recording Ogg VorbisYou can get extra side information while recording Ogg Vorbis data to see whether VS1053b is still working.The following VS1053b X memory addresses may be read for extra data:X Memory Address Description0x816LSb’s of recording time(seconds)0x916MSb’s of recording time(seconds)0xC16LSb’s of average bitrate(bits/s)0xD16MSb’s of average bitrate(bits/s)0x180016LSb’s of sample counter0x180116MSb’s of sample counterTo read the average bitrate,do the following.First write0xC to SCI WRAMADDR(7). Then read from SCI WRAM(6).This is16least significant bits of the bitrate.Then read the16more significant bits by reading SCI WRAM again.You can read the recording time as a sanity check that VS1053b is working:if the register contents don’t change every second,you’ll have to take protective measures.2.3.5Finishing Ogg Vorbis RecordingTo create fully compliant Ogg Vorbisfiles,Ogg Vorbis bitstreams need to be shut down properly.The following algorithm can be used to implement this:1.Set bit0of SCI AICTRL3(15)to1.2.Continue reading data through SCI HDAT0and SCI HDAT1as usual,but checkSCI AICTRL3’s bit1from time to time.When this bit turns to1,the Ogg Vorbis encoder hasfinished writing to the buffer.3.Write the remaining words from the bitstream buffer as normal using SCI HDAT0and SCI HDAT1.4.Read SCI AICTRL3twice(changed from version1.4!)and check whether bit2is1in the latter read.If it is,then don’t write to thefile the last byte(bits7:0)of the last word that have come through SCI HDAT0.5.Reset VS1053b to normal state using software reset.Remember to clear registerSCI MODE(0)bit SM ADPCM(12)if you don’t wish to start ADPCM recording.Remember to also set bit SM LAYER12(1)to an appropriate value.6.If you want to restart recording,you have to completely reload and restart therecording application.2.4Recording Levels and Automatic Gain Control(AGC) The VS1053b Ogg Vorbis Encoder offers signal level monitoring through SCI AICTRL0. It is recommended that devices that offer recording would show a signal level in a decibel scale.For the decibel scale,see Chapter2.4.4.This can be done by showing and clearing SCI AICTRL0contents at regular intervals.A good VU meter should be implemented in such a way that it visually advices the user to avoid using the last6dB of the available dynamic range.2.4.1Reading the Recording LevelThe recording level meter has two settings:mono and stereo.You can use mono mode with both mono and stereo streams,but you should use the stereo mode only with stereo profiles.The new meter is compatible with versions pre1.60if SCI MODE bit SM LAYER12is clearedfirst.Recording Level Meter:Mono ModeActivate mono mode by clearing SCI MODE(0)register bit SM LAYER12(1)to0.To read the level,repeat the following loop:•Write0x8000to SCI AICTRL0.•Wait for at least1/50s.Note:Omitting this step will not cause a malfunction, but constant reading of side information causes load on the VS1053and may cause unexpected crackles in sound.•Check whether SCI AICTRL0&0x8000is0.If not,wait a little more and read again.•Use the value as explained in this Chapter.Repeat the loop.Recording Level Meter:Stereo ModeActivate stereo mode by setting SCI MODE(0)register bit SM LAYER12(1)to1.To read the left and right channel levels,repeat the following loop:•Write0x8080to SCI AICTRL0.•Wait for at least1/50s.Note:Omitting this step will not cause a malfunction, but constant reading of side information causes load on the VS1053and may cause unexpected crackles in sound.•Check whether SCI AICTRL0&0x8080is0.If not,wait a little more and read again.Note:wait until both bits have cleared!•Left channel value is SCI AICTRL0&0x7F00.•Right channel value is(SCI AICTRL0&0x7F)×256.•Use the values as explained in this Chapter.Repeat the loop.2.4.2Setting AGCWhen the highest dynamic range and soundfidelity is required,AGC should be turned offand recording gain should be set to1(SCI AICTRL1=1024).A good example of this would be music recording.This is particularly recommended for the“HiFi Voice”and“Music”profiles,although there might be cases where recording level control would be needed even with these cases.However,in some cases it is required that the audio dynamic range is compressed.An example of such a case is when a device should retain a uniform recording level of a discussion of several people or of one person moving closer and further from the recording device.In such a case,it is a good idea to use AGC.The AGC unit adjusts signal power in such a way that the maximum sample value from a sine wave would become as close to16300as possible.If the signal is too strong, recording level is decreased,and vice versa.The maximum recording level can be set with register SCI AICTRL2.When AGC is used,conservetive maximum gain values often give the best sounding results.Example:12dB(SCI AICTRL1=0,SCI AICTRL2=4096).In some cases more extreme values may help to make quiet speech more intelligible,but such values may also add excessive background noise and make sound quality less pleasing.2.4.3Building a Useful VU MeterIn an encoder application,if the recording level is too low,extraneous background noise may be introduced to the sound.Conversely,if the recording level is so high that the highest values cannot be represented numerically,signal clipping occurs,and this may cause severe distortion to sound.In a recording device,it is useful to have a VU meter that shows the signal level so that both too low signal levels and clipping is avoided.This is very important so that the user has a chance to either adjust the recording or input signallevel.−40 dB = 161−30 dB = 512−20 dB = 1625−12 dB = 4096−6 dB = 81920 dB = 16384+5 dB = 29193OVERLOAD = 29193OVERLOADFigure2.1:Example Colour VUMeter.OVERLOADFigure2.2:Example Monochrome VU Meter.Figures2.1and 2.2show example VU meters.The0dB reference point has been set to signal level16384,which is one half of the maximum amplitude,leaving a6dB headroom for the device.The lowest signal level shown is a choice that can vary a lot depending on the application. While-40dB is a high-fidelity favourite,a VU meter will work just as well with a lower limit of-20dB.If display space is scarce,low limit could even be set to-12dB.Between-6and+6dB the VU meter precision should preferably be1dB,and at most 2dB.Below-12dB step size can be several decibels.The important thing in a VU meter is to visually show the user that it is not recommended to regularly use the highest6dB of the recording scale,and that an overload situation (≥+5dB,or over linear value29193)is an error condition.To help this the OVERLOAD symbol should be kept lit or blinking for at least2seconds each time an overload situation occurs.Many of these cues are often ignored in digital VU meters,and partly as a result of this even professional recordings are all too often made at recording levels that destroy signal integrity.Figure2.3:Real Record Display with Monochrome VU Meter.Figure2.3shows a real implementation of a recording display that uses a Monochrome VU rmation shown on the top line includes recording time,free disc space, overload warning and a bitrate counter.All this data except from the free disc space number have been obtained from the VS1053b Ogg Vorbis Encoder.Recording gain and AGC can be set at the center of the screen if a profile is used that support these functions.However,they are greyed out in this picture because they are not available in the Stereo Music profile that has been used.The VU Meter is at the bottom.The solid line is the current recording level as read from SCI AICTRL0and converted to Decibel scale as shown in Chapter2.4.4.The greyed line is the top level of the last3seconds.If the greyed line≥+5dB,the orange OVERLOAD message blinks twice a second for three seconds.2.4.4Converting from Linear to Decibel ScaleTo convert from linear to dB scale on architectures where multiplications and logarithms are expensive operations,the following code can be used:const unsigned short linToDBTab[5]={36781,41285,46341,52016,58386}; /*Converts a linear16-bit value between0..65535to decibels.Reference level:32768=96dB(largest VS1053b number is32767=95dB). Bugs:-For the input of0,0dB is returned,because minus infinity cannotbe represented with integers.-Assumes a ratio of2is6dB,when it actually is approx.6.02dB.*/unsigned short LinToDB(unsigned short n){int res=96,i;if(!n)/*No signal should return minus infinity*/ return0;while(n<32768U){/*Amplify weak signals*/res-=6;n<<=1;}for(i=0;i<5;i++)/*Find exact scale*/if(n>linToDBTab[i])res++;return res;}2.5Samplerate ConsiderationsThe Ogg Vorbis encoder cannot always work at exactly the right samplerate.To be exact, the samplerate is accurate only when the input clock is12.288MHz and the nominal samplerate of a profile is either8000Hz or16000Hz.In all other cases the samplerate can be calculated as follows.First let:•f i=input clock divided by4000(same value that you write to SC FREQ(bits10:0) of register SCI CLOCKF,or3072if you have written0to these bits to indicate12.288MHz clock).•f n=nominal samplerate of the profile(8000,16000or44100).•r=3if f n=8000,otherwise r=2.•Now let u=f n×r.•Let d= f i×2000+u2u•Now our real samplerate f s=2000×f id×rExample:We are running at an input clock of12.288MHz and we are running the Stereo Music profile that has a nominal samplerate of44100Hz.First f i=122880004000=3072.Because f n=44100,then r=2. Thus u=44100×2=88200.This leads to d= 3072×2000+88200288200 =70And,finally,our real samplerate f s=2000×307270×2≈43885.7(Hz)As can be seen,in this example the nominal and real samplerate have a difference of 0.5%.While this is normally not significant,it is good to know and important in the case of streaming.2.6Post-Processing the Recording with VorbisGainIt is recommended to post-process your own recording later on a PC machine using VorbisGain to get equal loudness with other recordings.For details,see Chapter3.3.3The Ogg Vorbis FormatThis chapter gives a brief introduction to the Ogg Vorbis format and presents recommen-dations for basic parameters when transcoding MP3files or compressing CD content into Ogg Vorbisfiles on a PC.The intent is to give VLSI Solution’s customers information on how to create high-quality Ogg Vorbis content.Before using the information in this document,you should get the free Ogg Vorbis encoder “oggenc”,minimum version1.0.2(2005),or a version with aoTuV tunings.While the instructions will work with older versions,sound quality will not be as good.Download oggenc at /.It is also strongly encouraged to get VorbisGain,a program that tagsfiles with loudness information(Chapter3.3).For this example,vorbisgain v0.36has been used.Download VorbisGain at /vorbisgain.html.3.1Introduction to Ogg VorbisOgg Vorbis is a license-free audio codec that allows for high-quality sound around a large gamut of bit-rates,ranging from roughly10to500kbit/s.With a given bit-rate,Vorbis is capable of surpassing the quality of MP2,MP3,WMA and AAC LC,particularly in low-bit-rate applications.An Ogg Vorbisfile is a Vorbis compressedfile that has been encapsulated inside an Ogg stream.The defaultfile extension for Ogg Vorbisfiles is“.ogg”.An Ogg Vorbisfile consists of two major parts:header and actual data.Every Ogg Vorbisfile begins with a header which contains compression tables that the decoder needs to correctly decodefirst.After the header has been fully received,Vorbis audio may be decoded.The size of the header information is around4KiB for most encoders. (However,for VLSI Solution’s VS1053b encoder,header size is only roughly1.5KiB.)After the header has been decoded,full random access is available in an Ogg Vorbisfile. As opposed to many other formats,an Ogg Vorbisfile contains its own time code,so absolute position in afile can be displayed after random access operations(fast forward /rewind).Ogg Vorbis is not particularly well suited for encoding very short,low bit-rate samples.E.g.a16kbit/s audio sample that lasts for one second would take2KiB for the actual audio data,so the default4KiB header triples thefile size.However,for normal appli-cations where audio lasts for more than10seconds,this header overhead is negligible.3.1.1Variable Bit-RateFor a long time almost all MP3files had a constant bit-rate,typically128kbit/s.While constant bit-rate(CBR)makes it easy to calculate a relation betweenfile size/position and song length,and while it makes it easier to streamfiles,CBR is not optimal for quality.When there is a difficult passage in music,there may not be enough bits available to encode audioflawlessly.Conversely,in passages that are easier to encode there may be bits left unused because the encoder didn’t need all the bits available in the bitstream.Where CBR tries to keep the bit-rate constant regardless of content,Variable Bit-Rate (VBR)tries to keep quality constant.This will have the effect of changing the bit-rate of thefile depending on how difficult a particular portion of music is to encode.Because sound quality is always kept constant,VBR has a bit advantage to CBR.Thus,VBR allows either for smallerfiles with the same perceived sound quality or equally sizedfiles with better perceived sound quality.Ogg Vorbis is by nature a variable bit-rate format and works best when this feature is not limited.Depending on the material the bit-rate can have significantfluctuations: e.g.songs that have been compressed with a quality setting with a nominal bit-rate of 96kbit/s can easily have average bit-rates between80to105kbit/s,or even more with extreme material.3.1.2TranscodingTranscoding is the process of converting from one lossy format to another,like from MP3 to Ogg Vorbis.It is important to understand that although Ogg Vorbis is a better format than MP3, transcoding never enhances sound quality.What has been lost in the initial MP3com-pression stage,will stay lost when converting to Ogg Vorbis,and there will always be some additional quality loss.While the extra quality loss can be small enough that it may be impossible to tell,the end result still is never better than the originalfile was. If possible,it it recommended that users should avoid transcoding to avoid generation loss.If transcoding is done(e.g.to get smallerfiles for a portable device),it is a good idea to keep the originalfiles.For best results,compress Ogg Vorbisfiles from uncompressed sources,like CDs.3.2Compressing into Ogg Vorbis with a PCThe whole process of getting Ogg Vorbisfiles looks roughly like this:•Preparation:Decode an MP3/WMA/AAC etcfile or preferably rip a CD to WAV format and make sure that you have“oggenc”(Chapter3.2.1).•Compression to Ogg Vorbis(Chapters3.2.2and3.2.3).•Optional post-processing with VorbisGain(Chapter3.3).3.2.1PreparationIf you intend to transcode(=recompress)MP3files,youfirst have to convert them to 16-bit RIFF WAV format(usually known for a“.wav”file name extension).However, before you do that,please have a look at Chapter3.1.2for details on transcoding.If you encode CDs,you have to make sure they are read initially into WAV format.It is recommended to use CD sources for compression if possible.When you have audio in WAV format,you can use oggenc to compressfiles,either in stereo or mono.Before continuing to the next stage,make sure you have the free Ogg Vorbis encoder “oggenc”,minimum version1.0.2(2005).3.2.2Compressing CD-Quality MusicIf we assume the inputfile is calledfile.wav and the output is to be calledfile.ogg,the following parameters may be used.It is assumed that the input audio is sampled at the CD44.1kHz sample rate.While these commands will also work for other samplerates,quality andfile sizes may differ.For each quality setting,the table shows the command needed to convert thefile,a typical bit-rate for that quality,how many hours of music could be stored to a1gibibyte memory card,and a short description of the mode.For comparison purposes,also an uncompressed CD bitstream is shown in the table.CD music compressionCommand Typ.Hours/Descriptionkbit/s1GiBoggenc-q-1file.wav4553Smallestfiles size,better than96kbit/s MP3 oggenc-q0file.wav6437Ok quality,equals112kbit/s MP3 oggenc-q2file.wav9625Better than most128kbit/s MP3files oggenc-q4file.wav12819Often CD transparentoggenc-q6file.wav19212CD quality almost alwaysCD1411 1.7Uncompressed CDGraphical front-ends usually contain one or several CBR bit-rate slider(s)and a quality slider that usually goes from-1to10.CBR sliders should be deactivated,and the quality slider should be set to the“-q”value presented in the table.。

vs1003播放MP3卡的问题
vs1003播放MP3卡的问题vs1003播放MP3卡的问题第二次制作MP3 了,把第一次搞得源码搬出来,按上边的说明接好线,结果发现,不能工作了,第一次的确调出来了啊,我还清楚地记得,虽然调处来了但是效果并不好啊,还是卡卡的,然而这次竟然连声音都没有,我崩溃了,苦恼自己上次没有做好笔录。
这次用到的模块和上一次一样,也是STM32F103RBT6 最小系统板,VS1003 模块,SD 卡模块,还有一个按键模块就这些。
SD 卡模块和stm32 通信采用的是SPI 接口,这里使用的是SPI1,vs1003 和stm32 通信也是SPI,这里使用是SPI2,sd 卡模块的引脚加上电源和地也就6 根,vs1003 的引脚相对较多,电源地2 根+SPI 的4 根+ XDCS 和XCS+DREQ 共9 根。
在这里我们使用了15 根杜邦线将他们连接到一起。
我在调试中有点着急,眉毛胡子一把抓,以为连接好硬件后,下载软件聚会OK 的,结果没有好的情况的下依然处在这种泥潭下,毫无头绪的找毛病,改改这,动动那,在没有搞懂状况的情况下。
既浪费时间又会让人恼火,仍无济于事。
建议,把两者区分开,先把vs1003 线拔下来,直接调试sd 卡模块,这样线少,不会产生凌乱的感觉。
sd 卡模块是采用的SPI1,对照原理图,将mosi,miso,sck,cs 一对一的重新接好,在初始化处设置断点,观察返回值是否为零。
进一步调试fat 初始化是否成功,按照这样的思想,同样调试vs1003.我就是这样终于vs1003 正弦测试成功。
但是,两者都能正常初始化没问题的情况下,依旧有一个让人头疼的问题,就是播放卡带的问题,就像老家使用VCD 播放电影时有卡带并且还有机关枪突突的声音,虽然能播放出来,但突突的断续却感觉不到成功的喜悦。
然后参考别人的代码,翻阅手册,SPIsetspeed()改大改小,屁变化没有。
那问题就出在SPI 的问题上,或者是SPI1 或者是SPI2,说不定两者在设置速率上都存。

基于语音识别的智能垃圾桶的系统设计方案-计算机应用技术论文-计算机论文
基于语音识别的智能垃圾桶的系统设计方案-计算机应用技术论文-计算机论文——文章均为WORD文档,下载后可直接编辑使用亦可打印——语音识别论文第三篇:基于语音识别的智能垃圾桶的系统设计方案摘要:阐述基于语音识别的智能垃圾桶的系统设计方案,将智能垃圾桶分为5大功能模块进行设计,此5大功能模块为红外线感测模块、语音识别及播报模块、机械控制模块、远程定位和通信模块,以及外观模块。
要想在智能垃圾桶中应用语音识别技术,还需要设置各功能模块相对应的硬件和软件,通过硬件与软件的共同作用,实现智能垃圾桶各功能模块的正常运行,以此达成语音识别和语音宣导的作用。
关键词:智能,垃圾桶;语音识别;应用;1 概述为更好地解决城市垃圾分类难题,可以借助技术手段来进行垃圾分类工作,以此提高垃圾分类工作的效果与质量。
基于语音识别技术设计了智能垃圾桶的系统方案,此方案既能使语音识别的功能达成,又能使语音播报发挥宣导作用,从而引导扔垃圾的居民正确进行垃圾分类投放的操作。
这对于解决垃圾分类难题有重要作用,能有效推进城市生活垃圾分类工作的开展。
2 系统方案设计在智能垃圾桶中应用语音识别技术的主要目的有两点,(1)进行垃圾名称的识别,比如干垃圾、湿垃圾、有害垃圾等。
(2)垃圾分类知识宣传,通过垃圾分类知识宣传提高人们的垃圾分类意识。
为实现这两大目的,应主要围绕智能垃圾桶的5大功能模块进行设计,此5大功能模块分别为红外线感测模块、语音识别及语音播报模块、机械控制模块、远程定位和通信模块,以及外观模块。
基于此5大功能模块的智能垃圾桶工作流程如图1所示。
图1 智能垃圾桶运行流程第1步:智能垃圾桶通过红外线感测功能感测垃圾桶周边范围内是否有扔垃圾的居民靠近。
第2步:一旦感测到有扔垃圾的居民靠近,就立马会启动语音识别及语音播报和机械控制功能模块。
从而进入交互状态,实现人与智能垃圾桶的交流互动。
第3步:当扔垃圾的居民说出所要扔的垃圾名称后,智能垃圾桶通过语音识别功能对居民所说的垃圾名称进行识别。

P3 接口不对外连接,当用跳线帽短接 P3 的 1 脚和 2 脚的时候(默认设置),咪头是直 接连接在 VS1053 芯片上的,录音的时候,我们可以直接通过咪头实现声音采集。当不采用 咪头拾音,而采用外部线路输入的时候,为了防止 MIC 拾音器对线路输入的影响,此时我 们拔了 P3 的跳线帽即可。
