Metadata in Speex encoded files

I can't find anything about metadata-handling in speex files on speex.org, so could someone please enlighten me?

Does Speex use vorbis comments? If not, does anyone know where I can find some information about speex tags?

Hi Florian,

Yes, Speex uses Vorbis Comments.

1.8 Ogg Vorbis, Speex
---------------------

  Ogg Vorbis [5] is an audio compression format designed for "mid to
  high quality" recordings of audio and music. Speex [6] is a low bitrate
  voice codec. The normal file storage method for these codecs is an Ogg
  bitstream, for which both make use of "Vorbis comment"[7] packets.


Addition: Ogg FLAC also makes use of Vorbis Comments.

Speex uses Vorbis comments -like tagging which is stored in packet number 1. Official speexenc encodes the tags incorrectly (no UTF-8) but otherwise it's good source for checking how the tagging works.

Case, I've just noticed the speexfile class in foo_speex and want to ask you if I may reuse portions of your code?

Sure. That's why the code is open.
