Hi,
I have downloaded Vorbis and played with it, and I have downloaded
Speex but not yet played with it. My understanding is that Vorbis
is targetted at high-quality audio (music) while Speex is targetted
at speech quality audio (telephoney and such). So I have two questions
to ask the group:
1. Which would your experiences show is the better codec for recording
high quality speech such as radio interviews?
2. Are the hardware player manufacturers looking at incorporating
Speex as well as Vorbis in the future?
TIA,
John.

IMHO, I don't believe it will make much if any noticeable difference when encoding at such low bitrates, where the sound is so drastically different to the original. Ross.

Vorbis seems more suitable for file-based spoken audios than Speex. There are also a number of non-quality issues to take into account: * It is unclear whether Speex will ever be included in hardware devices, * The Speex user base may not have the critical mass needed to ensure its survival, * It seems doubtful that it will ever be widely supported in software, * Unexpected non-spoken components trigger a switch to Vorbis anyway, and * There are advantages to using a single lossy format for all recordings. I regret these findings because I like the idea of having a format specificly targetted at speech, but for my purposes Vorbis seems the better choice at present. I do hope that Speex continues to flourish and improve, but suspect that it will do so more in arenas such as telephony.
