Constant Q Transform is a transformation for audio that uses a log scale for the frequency instead of a linear scale like FFT does. A fast implementation of Constant Q Transform uses FFT and a kernel.…

Constant Q Transform can show the volume of musical notes. `mpv` implements this filter.
```bash
mpv --lavfi-complex="[aid1]asplit[ao][a]; [a]showcqt[vo]"
```
This would be a nice visualiz…

**Resolution**
Anyone who has use spectrum to find anything useful generally uses logarithmic or melodic (which were bugged in an older version of audacity and gave incorrect scaling) has noticed t…

Although FFTs are fine, it gets really boring for me, so the constant-Q transform (actually the variable-Q transform) is preferred over FFT for octave band analysis, but [my implementation of CQT](htt…

### Feature Description
The external tool sv2v rewrites member accesses, element selects and other operations into part-selects and a bit of arithmetic.
Take e.g. ([source](https://github.com/op…

Variable-Q transform is very similar to constant-Q transform except the Q value is lower as the frequency decreases, which is useful if you want to have better time resolution on lower frequencies at …

## Description
When we do CDF regressions, the order statistic pdf updates the target density with the appropriate change of variables. There are 2 possible parameterizations. One involving the k_th …

**Is your feature request related to a problem? Please describe.**
Currently all constant Q operations call the `stft` operation with parameter `center=True`, which forces some sort of padding (e.g.,…
