[mary-users] exact Audio Format

[Pierre Lison]

Hello all,

I'm a hiwi student at DFKI (in the Cognitive Systems project), and  
I'm currently using Mary for the TTS module of our talking robots.  I  
have a small technical question to ask you: what is the *exact* audio  
format used in the output stream produced by the Mary client (ie by  
the process method), when "WAV" is chosen as the audio type ?

   What I would need to know is:
- the encoding format (ie. PCM, U-LAW, etc.) ;
- the frame size ;
- the frame rate ;
- the sample rate ;
- is it a big or little endian format ?

I want to pipe the output of the TTS to a stream over a (SIP-based)  
phone connection, where the audio format is U-Law 8 KHz.. and in  
order to convert the audio data into this particular format, I need  
to know the exact initial format first !  And I didn't find this  
information anywhere in the docs.

Thanks for your help !
