[speex-dev] replacing ACELP encoding with speex

[Jason Radford]

Hi all,

I'm to hit about aprox the same encoding settings (ie bitrate,filesize,
quality) with talk radio shows that are currently encoded with Real
Producer in 16kbit acelp (maybe cs-acelp).

Currently 2 hours of talk radio encoded in a .rm container yields about
16.3 meg file.  With speex in wideband vbr I'm getting very good quality
results, but with a larger filesize of 19.1 meg.

I'm currently using the command line below in a shell script, $1 is the
time in seconds, and $2 is just the file name specified.:

rawrec -d /dev/dsp -t $1 -s 16000 | speexenc -w --vbr --stereo - $2-$DATE.spx

I'm looking for some recomendations on getting down near or below 16meg
file size and maintaining the current 16k feed.

Thanks,

-Jason
