我有一个.wav
文件。我想从该声音文件中获取 PCM 数据,以便我可以从声音中获取各个数据块并进行处理。
但我不知道该怎么做。谁能告诉我该怎么做?到目前为止,我已经这样做了:
public class test
{
static int frameSample;
static int timeofFrame;
static int N;
static int runTimes;
static int bps;
static int channels;
static double times;
static int bufSize;
static int frameSize;
static int frameRate;
static long length;
public static void main(String[] args)
{
try
{
AudioInputStream ais = AudioSystem.getAudioInputStream(new File("music/audio.wav"));
AudioInputStream a;
int numBytes = ais.available();
System.out.println("numbytes: "+numBytes);
byte[] buffer = new byte[numBytes];
byte[] buffer1=new byte[numBytes] ;
int k=0;
int count=0;
while(count!=-1){
count=ais.read(buffer, 0, numBytes);
}
long value = 0;
for (int i = 0; i < buffer.length; i++)
{
value = ((long) buffer[i] & 0xffL) << (8 * i);
System.out.println("value: "+value);
}
} catch(Exception e) {
}
}
}
