Java中解析wav音频文件信息：音频声道数，采样频率，采样位数、声音尺寸

Java中解析wav⾳频⽂件信息：⾳频声道数，采样频率，采样位数、声⾳尺⼨前⾔：请各⼤⽹友尊重本⼈原创知识分享，谨记本⼈博客：
⾳频解析⽅法：
1public static int toInt(byte[] b) {
2return ((b[3] << 24) + (b[2] << 16) + (b[1] << 8) + (b[0] << 0));
3 }
4
5public static short toShort(byte[] b) {
6return (short)((b[1] << 8) + (b[0] << 0));
7 }
8
9
10public static byte[] read(RandomAccessFile rdf, int pos, int length) throws IOException {
11 rdf.seek(pos);
12byte result[] = new byte[length];
13for (int i = 0; i < length; i++) {
14 result[i] = rdf.readByte();
15 }
16return result;
17 }
⾳频解析⽅法调⽤：
1public static void main(String[] args) throws IOException {
2 File f = new File("E:/zmj-3011-32779/audio.wav");
3 RandomAccessFile rdf = null;
4 rdf = new RandomAccessFile(f,"r");
5
6 System.out.println("声⾳尺⼨: " + toInt(read(rdf, 4, 4))); // 声⾳尺⼨
7
8 System.out.println("⾳频格式: " + toShort(read(rdf, 20, 2))); // ⾳频格式 1 = PCM
9
10 System.out.println("声道数: " + toShort(read(rdf, 22, 2))); // 1 单声道 2 双声道
11
12 System.out.println("采样率: " + toInt(read(rdf, 24, 4))); // 采样率、⾳频采样级别 8000 = 8KHz
13
14 System.out.println("波形的数据量: " + toInt(read(rdf, 28, 4))); // 每秒波形的数据量
15
16 System.out.println("采样帧: " + toShort(read(rdf, 32, 2))); // 采样帧的⼤⼩
17
18 System.out.println("采样位数: " + toShort(read(rdf, 34, 2))); // 采样位数
19
20 rdf.close();
21
22
23 }
