无聊的时候玩玩讯飞tts，文字转语音，可是转出的语音是PCM格式的，无奈只好找转格式的代码。网上千篇一律，互相抄啊，终于找到可用的，但是语音却失真了(鼻音太重，小丸子的声音比蜡笔小新还重。。)，只好自己研究。。

后来经过一番思考，java本身是有播放语音文件的能力，网上搜刮了一篇java播放pcm的代码：

public class PcmPlayer {

public static void playPcm(File file) {

try {

int offset = 0;

int bufferSize = Integer.valueOf(String.valueOf(file.length()));

byte[] audioData = new byte[bufferSize];

InputStream in = new FileInputStream(file);

in.read(audioData);

float sampleRate = 16000;

int sampleSizeInBits = 16;

int channels = 1;

boolean signed = true;

boolean bigEndian = false;

// sampleRate - 每秒的样本数

// sampleSizeInBits - 每个样本中的位数

// channels - 声道数(单声道 1 个，立体声 2 个)

// signed - 指示数据是有符号的，还是无符号的

// bigEndian - 指示是否以 big-endian 字节顺序存储单个样本中的数据(false 意味着

// little-endian)。

AudioFormat af = new AudioFormat(sampleRate, sampleSizeInBits, channels, signed, bigEndian);

SourceDataLine.Info info = new DataLine.Info(SourceDataLine.class, af, bufferSize);

SourceDataLine sdl = (SourceDataLine) AudioSystem.getLine(info);

sdl.open(af);

sdl.start();

while (offset < audioData.length) {

offset += sdl.write(audioData, offset, bufferSize);

}

} catch (LineUnavailableException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (FileNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

可以直接播放PCM，然后突发奇想：既然能播放就能保存。想到就做：

public class Pcm2Wav {

public static void main(String[] args) throws Exception {

parse("d:/1.pcm", "d:/11.wav");

}

public static void parse(String source, String target) throws Exception {

float sampleRate = 16000;

int sampleSizeInBits = 16;

int channels = 1;

boolean signed = true;

boolean bigEndian = false;

AudioFormat af = new AudioFormat(sampleRate, sampleSizeInBits, channels, signed, bigEndian);

File sourceFile = new File(source);

FileOutputStream out = new FileOutputStream(new File(target));

AudioInputStream audioInputStream = new AudioInputStream(new FileInputStream(sourceFile), af, sourceFile.length());

AudioSystem.write(audioInputStream, AudioFileFormat.Type.WAVE, out);

audioInputStream.close();

out.flush();

out.close();

}

}

结果真的可以直接转换了，而且效果和pcm一样好。
