新建两个基础类

AudioOutputToByteArray

import be.tarsos.dsp.AudioEvent;
import be.tarsos.dsp.AudioProcessor;

import java.io.ByteArrayOutputStream;

public class AudioOutputToByteArray implements AudioProcessor {
    private boolean isDone = false;
    private byte[] out = null;
    private ByteArrayOutputStream bos;

    public AudioOutputToByteArray() {
        bos = new ByteArrayOutputStream();
    }

    public ByteArrayOutputStream getBos() {
        return bos;
    }

    public byte[] getData() {
        while (!isDone && out == null) {
            try {
                Thread.sleep(10);
            } catch (InterruptedException ignored) {}
        }

        return out;
    }

    @Override
    public boolean process(AudioEvent audioEvent) {

        bos.write(audioEvent.getByteBuffer(),0,audioEvent.getByteBuffer().length);
        return true;
    }

    @Override
    public void processingFinished() {
        out = bos.toByteArray().clone();
        bos = null;
        isDone = true;
    }
}

WaveHeader

import java.io.ByteArrayOutputStream;
import java.io.IOException;

public class WaveHeader {
    public final char fileID[] = {'R', 'I', 'F', 'F'};
    public int fileLength;
    public char wavTag[] = {'W', 'A', 'V', 'E'};;
    public char FmtHdrID[] = {'f', 'm', 't', ' '};
    public int FmtHdrLeth;
    public short FormatTag;
    public short Channels;
    public int SamplesPerSec;
    public int AvgBytesPerSec;
    public short BlockAlign;
    public short BitsPerSample;
    public char DataHdrID[] = {'d','a','t','a'};
    public int DataHdrLeth;

    public byte[] getHeader() throws IOException {
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        WriteChar(bos, fileID);
        WriteInt(bos, fileLength);
        WriteChar(bos, wavTag);
        WriteChar(bos, FmtHdrID);
        WriteInt(bos,FmtHdrLeth);
        WriteShort(bos,FormatTag);
        WriteShort(bos,Channels);
        WriteInt(bos,SamplesPerSec);
        WriteInt(bos,AvgBytesPerSec);
        WriteShort(bos,BlockAlign);
        WriteShort(bos,BitsPerSample);
        WriteChar(bos,DataHdrID);
        WriteInt(bos,DataHdrLeth);
        bos.flush();
        byte[] r = bos.toByteArray();
        bos.close();
        return r;
    }

    private void WriteShort(ByteArrayOutputStream bos, int s) throws IOException {
        byte[] mybyte = new byte[2];
        mybyte[1] =(byte)( (s << 16) >> 24 );
        mybyte[0] =(byte)( (s << 24) >> 24 );
        bos.write(mybyte);
    }


    private void WriteInt(ByteArrayOutputStream bos, int n) throws IOException {
        byte[] buf = new byte[4];
        buf[3] =(byte)( n >> 24 );
        buf[2] =(byte)( (n << 8) >> 24 );
        buf[1] =(byte)( (n << 16) >> 24 );
        buf[0] =(byte)( (n << 24) >> 24 );
        bos.write(buf);
    }

    private void WriteChar(ByteArrayOutputStream bos, char[] id) {
        for (int i=0; i<id.length; i++) {
            char c = id[i];
            bos.write(c);
        }
    }
}

现在新建执行类和方法，先在d盘放一个1.mp3的文件。以下代码就是把1.mp3转换成变声后的2.mp3

byte[] pcmBytes = speechPitchShiftMp3("d://1.mp3", 0.73, 0.73); 后面的0.73就是变声参数。最后会给出各种变声参数

	      //这里返回的是pcm格式的音频
	      byte[] pcmBytes = speechPitchShiftMp3("d://1.mp3", 0.73, 0.73);
	      
	      //如果需要转成wav则需要给pcmBytes增加一个头部信息
	      //TarsosDSP中也有输出Wav格式音频的处理器，这里没有使用。
	      byte[] wavHeader = pcm2wav(pcmBytes);
	      OutputStream wavOutPut = new FileOutputStream("d://2.mp3");
	      wavOutPut.write(wavHeader);
	      wavOutPut.write(pcmBytes);
	      wavOutPut.flush();
	      wavOutPut.close();

	      // 对于各种声音类型，以及所需添加的处理器，还有处理器参数代码，将在本文最后给出。
	      //如果需要转mp3格式的，也可以给我留言，我会加上。
	}

byte[] pcmBytes = speechPitchShiftMp3("d://1.mp3", 0.73, 0.73);改为
