For ability run mostly models for Sound Processing, Analysis on iOS there is missed step for sound preprocessing/post-processing: melspectrogram, stft, istft and others…

Now I’m ported such important methods:

  • stft
  • istft
  • melspectrogram

Actually project hosted at:

Available via CocoaPods and Swift Package Manger(*)

stft(Short-Time Fourier Transform):

(Article about Fourier Transform and Spectrogram: [link]])

istft(Inverse Short-Time Fourier Transform)


Mel spectrogramm visialisation

Main goal get same results as in python librosa for ability posing sound/audio solutions to iOS/MacOS.
