What it does

Speedo Drums by Spectral Pitch Shifting

Illustrates the use of the "Spectral Shift 2" block for perfoming multiplicative spectral shifting. The underlying algorithm is based on the FFT for converting to the frequency domain, shifting all frequency bins by the desired relative amount, then transforming back to the time domain. A wide range of effects can be achieved with this technique. Try experimenting with all sliders to explore the various possibilities. With the default settings, the drum track ("drums.wav") adopts a bizarre pitch and tempo (enhanced by the echoes caused by the double-overlapped buffers integral to the "Spectral Shift 2" block).
