Can we compute a mel-scaled spectrogram?

[vemusharan]

Is there any function which creates the mel-scaled spectrogram? There is a functionality in librosa librosa.feature.melspectrogram(), is there any similar method in .js?

Thank you

I don't think we support that right now, but maybe we could - we support MFCCs, so I would think those are related. Are you interested in working on that?

Thanks a lot @hughrawlinson for quick response. Yes, I would like to work on that. Could you please guide me :)

Absolutely! The first step would be to do some research and find a few different sources for the definition of this feature. We've found that often, different implementations of features do slightly different things or use slightly different terminology. We want to be approachable for developers coming from other tools, and try to keep the terminology we use similar to what other tools do. I'd suggest having a look at YAAFE, librosa, and essentia. Additionally, if there are any academic papers on the subject, those would be useful too. Let me know what you find and we can move on to the next step 😄

Let's keep this issue open to track the implementation?
