Power Spectrum from STFT (e1071)?
Hello.
Does anyone know how to generate a power spectrum from the STFT function in
package e1071? The output for this function supplies the Fourier

spectrum.
Alternatively, if anyone is aware of other packages/functions that perform
short time Fourier transforms, that would also be helpful.
Thanks...

Increasing the speed of speex playback
You're asking the wrong question. The question is not "why does it
would bad with Speex?", but "why does it sound good with LPC10 and
MELP?". And the answer is that both are vocoders. Try dropping
frames/subframes with anything else (Vorbis, MP3, G.729, u-law, ...)
and it'll sound terrible as well. The only reason it sounds good with
vocoders is because the
