Hi Waldo, Doesn't * record to .gsm file initially and then convert these to .wav later? I may be totally off the mark here, and if I am, I welcome the correction. In that case, why not leave the files in .gsm format instead of translating them into another lossy format? Obviously if * records conversations as .wav files then I'd be leaning toward Speex (Vorbis) as it is a suited to speech compression format. Both Speex and ogg are Open Source, therefore patent issues are likely non-existent. MP3, otoh, is fine if you use one of their approved apps, and not if you use anything else.

Hilton, AFAIK, you can optionally record in gsm. However, I think * won't do it natively. It will do -in and -out wav files, soxmix them together and then convert them to gsm.

Re: [Asterisk-Users] MP3 or OGG
I tried Speex and the quality is much better than using lame to convert to mp3 or the ogg version. File compression is still better in mp3 than speex (mp3 is approximately twice smaller than speex), but I could live with it. Speex file size is still approximately 8 times smaller than WAV.

In the past, I've use lame to convert to MP3, but I noticed the audio volume drops significantly. Is it just a setting on the command line of lame or is OGG better? Which achieves higher compression rates while maintaining call quality?

RE: [Asterisk-Users] MP3 or OGG
Hey Waldo. AFAIK there is quite a lot of scope for tuning the compression of speex - just as there is for mp3. I have no doubt that if you tune complexity, quality and bitrate parameters you will be able to get that filesize down even further. Can't see any reason at all why you shouldn't be able to whack mp3 for filesize.

File compression is still better in mp3 than speex (mp3 is approximately twice smaller than speex), but I could live with it. Speex file size is still approximately 8 times smaller than WAV.

Re: [Asterisk-Users] MP3 or OGG
I'm sure there are. I've only used the stock command interface with no options. We'll continue tuning. Thanks, Waldo On Nov 8, 2005, at 7:43 PM, Mark Edwards wrote: Hey Waldo.

RE: [Asterisk-Users] MP3 or OGG
I would recommend vorbis speex for this. You can get windows drivers to read speex files directly. Vorbis are the same bunch that develops ogg. Ogg and mp3 are more suited to music rather than speech. Speex is a much better fit for speech archiving.

Re: [Asterisk-Users] MP3 or OGG
Wasn't aware of it, but if quality is good, it makes sense since all I'm archiving is speech. Will evaluate further.
