my_stft#

hmc_mir.tsm_tools.tsm_tools.my_stft(x, N, hop_length, window)[source]#

A custom implementation of the STFT that allows for non-integer hop lengths (in samples).

Parameters:

  • x – the input audio waveform

  • N – the FFT size

  • hop_length – the hop size specified in samples, can be a non-integer

  • window – the window to apply to the analysis frames

Returns:

  • X – the computed STFT matrix

  • frame_offsets – a list specifying the offsets (in samples) of each analysis frame
