Hi', since speex decoder is available now for Palm OS also, I was wondering if I can get some good results for audio books . Currently I'm using 22khz around 20kbps (q -2 ) with ogg.
Whatever settings i tried (quality/ bitrate/complexity) - I can't bet speex to sound better ogg per same bitrate. This doesn't make any sence, because speex is supposed to be tuned specially for speach.
Moreover, it doesn't obey my commands, for example I wanted to force it to use bitrate of 10 kbps
QUOTE
--bitrate 10 --vbr --comp 6 o:\test\16khz.wav o:\out.spx

Instead, i get bitrate of arund 20, which sound much worse than ogg@20kbps. Why?
Can anybody help me?

I think --vbr and --bitrate 10 are not meant for each other.

Can you recommend some good settings than? I've tried sample files from speex.org site , and they are pretty good, even at 10kbps. I just can't get even close to it.
