pitch_shift()

template<typename SampleType = float>

std::vector< SampleType > pulp::signal::PhaseVocoderT< SampleType >::pitch_shift ( const std::vector< SampleType > & input, double semitones ) const

inline

Pitch-shift input by semitones (positive = up), preserving duration.

Returns a new buffer the same length as input. Inputs shorter than fft_size are returned unshifted (one analysis frame is the minimum the phase vocoder can process).

time_stretch()

template<typename SampleType = float>

std::vector< SampleType > pulp::signal::PhaseVocoderT< SampleType >::time_stretch ( const std::vector< SampleType > & input, double factor ) const

inline

Time-stretch input by factor (> 0).

Output is exactly round(input.size() * factor) frames long and keeps the same pitch. factor == 1 is ~identity. factor is clamped to a sane maximum (kMaxStretch) so an absurd value can't request a multi-gigabyte buffer.
