What’s a Speex file?

Filed under: English, FLOSS, Standards, lever, uptime Robin @ 16:03 (2458 lectures)

Prompted by Mark’s question, Speex is a codec from the vorbis family. It’s designed specifically for voice/speech and thus generally gives a smaller file size than an mp3 or ogg vorbis file. I use ogg123 on gnu/linux; for ms windows I was using foobar 2000, but ms media player with the right DirectShow filters will do the trick; finally on a Mac with OS X 10 you can use the darwin ports, QuickTime components for iTunes, fink or collect a bounty if you swing that way.

Ogg, Speex, Vorbis, what’s the difference?

Ogg is a container format for holding multimedia data. Vorbis is an audio codec that uses Ogg to store its bit-streams as files, hence the name Ogg Vorbis. Speex also uses the Ogg format to store its bit-streams as files, so technically they would be “Ogg Speex” files (I prefer to call them just Speex files). One difference with Vorbis however, is that Speex is less tied with Ogg. Actually, if what you do is Voice over IP (VoIP), you don’t need Ogg at all. – from the FAQ

  1. Ogg Vorbis streams for the CBC
    Last night, I found out through Peter on the MLUG mailing list that the CBC now provides audio streams in an open format, available for many platforms. Sylvain Carle picked up the story, bringing joy to Benoit St-André :)

  2. On Linux, you can also use the popular XMMS player. On Windows, the not-so-free Winamp handles is, but I’d suggest Zinf, which is more free (as in speech). Grab a *beer* and listen up ;)
