#2 AUDIO_ALAW.PCM FORMAT

[David Viamonte]

Hi,
This is David Viamonte from Spain. I'm currently
working with CallGen323 in order to perform some
capacity tests of a VoIP system and I'm interested on
the audio_alaw.pcm file required by the program.
Basically, the two topics I'm interested on are the
following ones:

- Is this "*.pcm" file format a kind of sound
recording format or just a raw file containing only 8-
bit PCM samples of speech ?

- Is there any available (freeware, shareware, ...)
tool to easily record this file format from the
microphone attached to the sound board in order to use
it with the CallGen323 app ?

Thank you in advance for your help.

David
