convert GSM to PCM (wav)

hello the masters of JAVAPF,,
i'm newbie in Java Programming

can anyone tell me , how to convert GSM to PCM (wav)
pliz i need your help !![-O<

Firstly welcome to java programming forums. Secondly this is the wrong thread, it shouldn't be in tutorials.

Thirdly, you'd have to expand the abreviations i.e gsm pcm, are you on about pulse code modulation? and what about gsm?

Hello cilang. Welcome to the forums.

I have moved this thread over to our Advanced Java forum.

I have no idea about GSM or PCM!! :-s Could you please explain in more detail?

@ chris : Thanks for your help. :)

@ JavaPF :

So, I have an audio file which has .wav extension property like this:

bit rate 13kbps
channels mono (1)
audio sample rate 8kHz
audio format GSM 6.10

The problem is, the type of this kind of audio is not suport in JAVA low-level API. Because, the audio file which supports in Java has the property like this:

bit rate > 16kbps
audio sample size bit
channels mono/stereo
audio sample rate 22/44 kHz
audio format PCM

I need the method converter from GSM6.10 (wav) to PCM (wav), with the parameter input (file) source, and return to (file) target.

Thanks before for your help :)

my advice google, wav gsm to wav pcm and get a convertor :)
