**MFCCs** are commonly derived as follows:
- Take the Fourier transform of (a windowed excerpt of) a signal.
- Map the powers of the spectrum obtained above onto the mel scale, using triangular …

I've done a fair amount of work on this, adding in beat detection, more effects, and tidying up some of the code to make it more flexible for new effects - [Here's a quick preview](https://streamable.…

#### Description
* Compute CQT.
* Display with `librosa.display.specshow()` and `y_axis='cqt_note'`
* Note axis has offset by one semitone.
#### Steps/Code to Reproduce

Using a combination of a low n_fft, high n_mels, and low fmax, one can obtain a mel spectrogram where some of the bins are always 0. I haven't examined the source code but my guess would be that this …

Currently, the triangular weighting for spectrum frequency bins is computed on the fly inside compute(). We should consider precomputing filter weights just as it is done in [MelBands algorithm](https…

I'm plotting a spectrogram using librosa.display.specshow. I want to zoom in on the first 5 seconds, and the frequencies up to 2 kHz. I try `librosa.display.specshow(librosa.logamplitude(S), sr=sr, …

Right now, we only have Hann window in there, but we could add all of the scipy window functions.
Side note: the value currently recorded is half width half max. Would it be clearer to change this to…
