Sabrina,
please contact the editor of faac if you have specific questions with regard to 
that software.
Beside this it seems that faac requires a library (libsndfile) to support any 
audio format beside raw pcm. I wonder what format your myaudio.pcm has (probably 
wav). If it would be raw, than you would have to tell the encoder a couple of 
paramerers, e.g. the sampling frequency, the number of bits per sample, the 
number of channels and so on. Isn´t this obvious?
Best regards,
Ralph
