Seems like we ought to be able to do this, if we preserve phase in the cqt.
The main barrier comes from variable_hop, which uses oversampling and aggregation to handle large …

This is more of a feature request than a bug, so feel free to send me to a different forum if this is not appropriate. I was trying to see if LibROSA had any filterbanks to tranform an STFT into have …

* Display with `librosa.display.specshow()` and `y_axis='cqt_note'`
* Note axis has offset by one semitone.

Hi,
I compute the mel spectrogram on a time-domain signal that has `13230080` samples, like so:
mel_spectrogram = librosa.feature.melspectrogram(audio_data, sr=44100, n_fft=2048, hop_length=…

Hey there,
I recently did a DTW implementation based on Meinard's book with some Cython speed up for the dynamic programming.
As this is not yet reflected in librosa, I wondered if we could do a modu…

Hey there,
what about adding a salience function to librosa à la Justin Salamon for analysis tasks?
One way to do it is with a Reassigned Spectrogram based on a instantaneous frequencies.
Then add th…

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…

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, …

1. It would be neat to be able to plot piano rolls in librosa. Preferably with F-measure displayed as well (preferably by going through @craffel's [mir_eval](https://github.com/craffel/mir_eval)). E.g…

[EDIT: generalizing this from a previous idea]
The display module currently plots features/spectrograms in frame or bin units, rather than time or frequency. This makes it difficult to interact with…
