We have the ConstantQ transformation implemented (#136) but the spectrogram computation itself is missing.

Implement an algorithm for computation of spectrum based on Constant-Q similar to Spectrum. Re-use parts of implementation from Chromagram.

Input:

  • frame (vector_real)

Output:

  • spectrumCQ (vector_real)

Parameters (similar to Chromagram):

  • maxFrequency
  • minFrequency
  • binsPerOctave
  • sampleRate
  • threshold
