ADPCM and GSM to wav file with RAWCONVERTER

Question

Hi, is it possible to codify ADPCM and GSM in a .wav file with the RawAudioDataConverter(jsresources) or do they need a targetEncoding?. I have recorded GSM data in a wav file but I can't decode them.
Example of my GSM coder and decoder
AudioInputStream ais = null;
          AudioFormat.Encoding targetEncoding = null;
          AudioInputStream audioInputStream;
          File encodedFile = null;
encodedFile = new File("gsm" + audioFile.getName());
               try
                    ais = AudioSystem.getAudioInputStream(audioFile);
               } catch (Exception e)
                    e.printStackTrace();
               if (ais == null)
                    System.out.println("No se puede abrir el archivo");
               AudioFormat sourceFormat = ais.getFormat();
               if (!sourceFormat.getEncoding().equals(
                         AudioFormat.Encoding.PCM_SIGNED)
                         || sourceFormat.getSampleRate() != 8000.0F
                         || sourceFormat.getSampleSizeInBits() != 16
                         || sourceFormat.getChannels() != 1)
                    System.out
                              .println("The format of the input data has to be PCM 8 kHz 16 bit mono");
                    System.exit(1);
               AudioFormat.Encoding targetEncod = new AudioFormat.Encoding(
                         "GSM0610");
               AudioInputStream gsmAIS = AudioSystem.getAudioInputStream(
                         targetEncod, ais);
               AudioFileFormat.Type fileType = new AudioFileFormat.Type("GSM",
                         ".gsm");
               int nWrittenFrames = 0;
               try
                    nWrittenFrames = AudioSystem.write(gsmAIS, fileType,
                              encodedFile);
               } catch (IOException e)
                    e.printStackTrace();
               }Example of my GSM decoder:
private File decodificar(File FileIn)
          AudioInputStream ais = null;
          File in = new File(archivoCodificado.getName());
          File FileOut = new File("decod" + in.getName());
          try
               ais = AudioSystem.getAudioInputStream(in);
          } catch (Exception e)
               e.printStackTrace();
          if (ais == null)
               System.out.println("cannot open input file");
          AudioFormat.Encoding targetEncoding = AudioFormat.Encoding.PCM_SIGNED;
          AudioInputStream pcmAIS = AudioSystem.getAudioInputStream(
                    targetEncoding, ais);
          AudioFileFormat.Type fileType = AudioFileFormat.Type.WAVE;
          int nWrittenBytes = 0;
          try
               nWrittenBytes = AudioSystem.write(pcmAIS, fileType, FileOut);
               System.out.println("AudioDecoder: written (bytes): "
                         + nWrittenBytes);
          } catch (IOException e)
               e.printStackTrace();
          return FileOut;
     }I think that it might be well recorded but it doesn't works, giving and exception. I think that its all right because the number of byts in my GSM recorded file is about the tenth part of a PCM lineal file, and when I try to reproduce it with winamp for example it detects a sound track but it can't calculate the length of the GSM file(wav extension I mean)

QuickTime Player X does not export WAV. You could use QuickTime Player 7, which if it's not in your Utilities folder already can be installed from the Optional Installs on the Snow Leopard install disk, but you'll need to purchase a QuickTime Pro key.
