Do you mean that speex is working at 44.1 Khz like at 32Khz without samplerate conversion ? It seems you suggest that working with 44.1 Khz signal instead of 32Khz (wich is the native samplingrate for the ultra -wide-band mode as far as i understand) ask for more CPU load. Since YOU have already worked with SPEEX, do you know how much CPU load it takes ? 10% more ? 50% more ? > In short - you must do up/down-sampling by yourself.

Hi I download the libvorbis-1.1.1 and use the encoderexample.c and decoderexample.c to drive it. The parameters i used is samplingrate: 44.1kbps, channel number: 2, quality :0.4. Now I want to compare it\\\'s complexity with MPEG-2 AAC, but don\\\'t know how to trace into the lib , can you tell me how to do that or tell me how many addtions and multiples does the vorbis use under those parameters...

Hello folks I am encoding music to ogg vorbis format for the first time. From what i have researched, ogg vorbis is natively a vbr format. Also encoding using the -q switch is encouraged instead of specifying a bitrate through -b. Now, while encoding using -b i get this: Encoding "file.wav" to "file.ogg" at approximate bitrate 224 kbps (VBR encoding enabled) Notice
