ep-4xx13 DSP – week 4



  • fft-tz.maxpat: demonstrates fft transform to the frequency domain. Also a puzzling bit of complex multiplication in the time domain.
  • fplanet-tz.maxpat: hacked version of forbidden-planet example which uses granular indexing to do spectral convolution and make spaceship sounds. To use patch:
    •  turn on audio,
    • then press message boxes inside the green panel
  • fp-fft-tz.maxpat: pfft~ subpatch for above
  • fourierfilter (folder) containing fourierfiltertest.maxpat: Katja Vetter’s complex spectral filter example
