calculateMFCCs abstract method

Future<Float64List?> calculateMFCCs({
  1. required List<double> signals,
  2. required int sampleRate,
  3. required int hopLength,
  4. required int nMels,
  5. required int fftSize,
  6. required int mfcc,
})

Calculates the MFCC matrix of the mono samples signals.

The bundled Android and iOS implementations validate fftSize but currently ignore it: jlibrosa uses a fixed FFT size of 2048, and iOS mirrors it.
