android - オーディオトラックで PCm データを再生する

Question

audiotrack を介して pcm データを再生しようとしたときに、jLayer lib を使用して mp3 をデコードしましたが、多くのオーディオ歪みが生じています。

私のデコーダコード:

public static void decode(String path, int startMs, int maxMs) 
              throws IOException {
              ByteArrayOutputStream outStream = new ByteArrayOutputStream(1024);

              float totalMs = 0;
              boolean seeking = true;

              File file = new File(path);
              System.out.println("the data "+path);
              InputStream inputStream = new BufferedInputStream(new FileInputStream(file), 8 * 1024);
              try {
                Bitstream bitstream = new Bitstream(inputStream);
                Decoder decoder = new Decoder();

                boolean done = false;  
                while (! done) {
                  javazoom.jl.decoder.Header frameHeader = bitstream.readFrame();
                  if (frameHeader == null) {
                    done = true;      
                  } else {
                    totalMs += frameHeader.ms_per_frame();

                    if (totalMs >= startMs) {   
                      seeking = false;
                    }  

                    if (! seeking) {
                      SampleBuffer output = (SampleBuffer) decoder.decodeFrame(frameHeader, bitstream);

                      if (output.getSampleFrequency() != 44100
                          || output.getChannelCount() != 2) {
                       // throw new com.mindtherobot.libs.mpg.DecoderException("mono or non-44100 MP3 not supported");
                      }

                      short[] pcm = output.getBuffer();
                      byte[] bs;
                      int index=0;
                      ByteBuffer buffer;
                      buffer = ByteBuffer.allocate(2*pcm.length);

                      for (short s : pcm) {     
//                      outStream.write(s & 0xff);      
//                      outStream.write((s >> 8 ) & 0xff);   


                        buffer.putShort(s);



                      }      

                      byte[] dataaudio = buffer.array();

                      //return buffer.array();






                      track.write(dataaudio, 0, dataaudio.length);

                    }   

                    if (totalMs >= (startMs + maxMs)) {
                      done = true;
                    }
                  }
                  bitstream.closeFrame();
                }

                //return outStream.toByteArray();
              } catch (BitstreamException e) {
                throw new IOException("Bitstream error: " + e);
              } catch (DecoderException e) {  
                Log.w("data", "Decoder error", e);
                ;
              } finally {
               // IOUtils.safeClose(inputStream);     
              }
            }
