Pitch Quantization Prototypes
OTTO is a pitch correction/quantization tool that includes key, scale and wet/dry mix parameters. The ottos.zip archive contains 6 versions. Ottotoon is the original and uses the grain delay to apply the pitch shift. Ottocomb uses a comb filter in high resonance to apply a quantized pitch to the input. Ottocode uses two vocoders to affect pitch. Ottofreq uses the FFT phase vocoder core module. Ottofreq mono is simplified. Ottofreq poly includes three voices for polyphonic harmony. These are experimental files without version numbers yet so stay tuned for updates as this effort is improved.
