java实现变声器--变声萝莉

编写java变声器需要做的前期准备

安装 ffmgeg 下载地址 Releases · BtbN/FFmpeg-Builds · GitHub

win系统下载 ffmpeg-N-103272-g7bba0dd638-win64-gpl.zip

配置环境变量到 bin目录

新建maven程序加入两个引用

<!-- https://mvnrepository.com/artifact/com.github.st-h/TarsosDSP --><dependency><groupId>com.github.st-h</groupId><artifactId>TarsosDSP</artifactId><version>2.4.1</version></dependency><dependency><groupId>ws.schild</groupId><artifactId>jave-core</artifactId><version>2.4.6</version></dependency>

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;}@Overridepublic boolean process(AudioEvent audioEvent) {bos.write(audioEvent.getByteBuffer(),0,audioEvent.getByteBuffer().length);return true;}@Overridepublic 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

各种参数类

LUOLI(0.6, 0.6, "萝莉", 1, dispatcher -> {})

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

byte[] pcmBytes = speechPitchShiftMp3("d://1.mp3", 0.6, 0.6);就可以了
