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

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?<BR>

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. <BR>
<BR>
Thanks a lot in advance.<BR>
<BR>
<BR>
Kind regards,<BR>
