新建两个基础类

AudioOutputToByteArray

        @Override

        public byte[] getHeader() throws IOException {
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            WriteChar(bos, fileID);
            WriteInt(bos, fileLength);

            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 );

    }

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

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