Description

STFT allocates an output buffer, but sometimes you might want to have it compute directly into an existing buffer. For example, in griffin-lim, the method alternates stft/istft for each iterate, which is then discarded. It would be better if we could give it an out= variable, which it would use instead of allocating a new buffer; this way, we could cut down on redundant mem

In PyAudioAnalysis > audioFeatureExtraction.py, there is stEnergyEntropy.

I can not understand what is the difference between 'Eol' and 'numpy.sum(sub_wins ** 2.)'

Plz let me know, the differece of two things( 'Eol' and 'numpy.sum(sub_wins ** 2.)')

Hi there, this is something might be useful if it's put in the Wiki.

I've had a problem with sudo modprobe snd-aloop and adding snd-loop to /etc/modules. As the title suggest this reorders the card order during boot. Since I've only got my own setup to compare against I'll just assume that people with other GNU/Linux distros might bump into the same problem. I use Debian.

Anyway, what

🐛 Bug

In order to enable inversion of an STFT via the inverse STFT in istft, it is sufficient that the signal windowing obeys the constraint of “Constant OverLap Add” (COLA). This ensures that every point in the input data is equally weighted, thereby avoiding aliasing and allowing full reconstruction.

Either as its own file, its own page, or as a section in the README.

Certain questions get asked again and again, and while a FAQ won’t prevent from getting them asked, some users might actually see it, and for those that don’t, it’ll be an easy place to point to when they do get asked, instead of having to type out new variations of the essentially same paragraphs time and time again. :)
