Spectrum Analysis





From a the audio file, different analysis are done :

  • Time analysis based on the calculation of the rms value on the frame time entered by the user.
  • Spectrum analysis based on the calculation of the 1-D discrete Fourier Transform for real input based and averaged on all the samples (total time divided by the time sample entered by the used) - Source : scypy.rfft
  • Spectrogramm analysis based on the calculation of consecutive Fourier transforms end time frame entered by the use - Source : scypy.spectrogramm
  • Octave spectrum : This method uses a Butterworth filter with Second-Order Sections coefficients with an Order of Butterworth filter of 16 - Source : PyOctaveBand
