Re: [Bayonne-devel] Bayonne generated wav files are rather large.

[David Sugar]

In Bayonne, we use by default 8khz 8 bit (u/alaw) because this is about the 
highest quality one gets out of the phone lines, because all telephony 
drivers support this format directly, and because disk space is relativily 
cheap these days.  There is adpcm, and sometimes it is sampled 4 bit adpcm at 
6khz, although not all telephony drivers support this and that then requires 
additional host processing for those that don't.  It is also possible to use 
vox functions to eliminate silent sections, and it could be possible to add 
that support to Bayonne drivers.
