Could I cluster the audio clips in order to improve the speed of their classification?

I have a neural network which is very resource intensive and is used to classify audio clips. The classification is done in batches, where I record for a set period of time and then go through and ...

How does using complex weights in a neural network affect performance?

If you switch a neural network from real weights to complex weights, you're roughly doubling the size of the network, and increasing the computational load by a factor of 2 to 4. My question is, in ...

Is it realistic to train a transformer-based model (e.g. GPT) in a self-supervised way directly on the Mel spectrogram?

In music information retrieval, one usually converts an audio signal into some kind "sequence of frequency-vectors", such as STFT or Mel-spectrogram. I'm wondering if it is a good idea to ...

Model for direct audio-to-audio speech re-encoding

There are many resources available for text-to-audio (or vice versa) synthesis, for example Google's 'Wavenet'. These tools do not allow the finer degree of control that may be required regarding the ...

I want to determine how similar a given song is to Queen's songs. Am I headed in the right direction?

I've asked this question before (@ Reddit) and people suggested CNNs on a mel spectrogram more than anything else. This is great. But I'm sort of stuck at: label some music data as "queen" ...
