Inverse spectrograms are used in the WikiDelia to reconstruct otherwise unknown audio where only spectrograms of them are available.

The software to do this is freely available on github.

  • Pot Au Feu early version, to get an idea of the audio quality of the reconstructions
  • Singing Waters, a rain-falling effect whose spectrogram resembles the layout of the poem it tells
  • Robert Lowell, a 4-minute evolving soundscape, reconstructed from only 4 pixel columns per second
  • Random Together 1, 2m30 of cacophony, not helped at all by the reconstruction!
