Computing multiple spectrograms (ID files)

Computing multiple spectrograms (ID files)#

In this example, we want to export spectrograms drawn from the sample audio dataset with the following requirements:

  • Start timestamps of the audio files are unknown

  • One single 8 s-long spectrogram should be exported per audio file

  • Audio data are downsampled sampled at 24 kHz before spectrograms are computed

  • The DC component of the audio data is rejected before spectrograms are computed

  • Exported spectrogram images should be named after the audio file IDs

The FFT used for computing the spectrograms will use a 1024 samples-long hamming window, with a 128 samples-long hop.
