[Vorbis] OGG decoding/multi-channel mixing

[Joost Meijles]

Hi All,
 
Thanks a lot for the many responses, they are very helpful to me (they made me enthousiastic about Ogg and the community).

I know that for decoding MP3 around 9 Mhz is needed, when using optimized code. How does using mono, effects the CPU usage? Does it half the requirement to around 20 Mhz?

Does anyone know of an implementation that has been created for Ogg (preferably capable of running on ARM) that provides mixing of multiple streams? I understood that somehow a Tremor implementation is available, but I did not quite understand that. 
 
Thanks a lot in advance.
 
 
Kind regards,
 
Joost
