What it does
Live Guitar Weird Spectral Shift
Demonstrates the use of WaveWarp's live input functionality. Plug an electric guitar (or any other audio source!) into the "input" of your soundcard and hit "Play". You will experience the weird effects achievable using the "Spectral Shift 1" block for perfoming linear spectral shifting. The underlying algorithm is based on the FFT for converting to the frequency domain, shifting all frequency bins by the desired amount, then transforming back to the time domain. A wide range of effects can be achieved with this technique.
Experiment with all settings and with different input sources (works particularly well with vocals)!
