This repository has the source code for computing spectrogram with torch. When processing audio signals, it can be done quickly in batch processing.

Spectrogram in torch_spec.py

• STFT : same with librosa.stft
• MelSpectrogram : same with librosa.feature.melspectrogram
• LMLFSpectrogram : same with madmom.spectorgram.LogarithmicFilteredSpectrogramProcessor

Verification with packages

If you run torch_spec.py, you can see the result as shown below.
