SPEEX on iPhone ?
...; Thus if you feed algorithm with wrong freq, you'll fool it and it might
> even not detect speech at all.
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 ?

libspeex crash with RC3
I tried to compress 160 samples of random garbage (range 0-500.f) at 4kbps
and got a crash in nb_encode -> forced_pitch_quant because start

the complexity of ogg-vorbis
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 ?...

Standard sample rate used with speex is 8kHz.
Speex wideband uses 16kHz
Speex ultra-wideband uses 32...

oggenc -q switch vs -b switch
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)
