Functions
std::vector< double >	MayaFlux::Kinesis::Discrete::apply_spectral (std::span< const double > src, uint32_t window_size, uint32_t hop_size, const SpectrumProcessor &processor)
	Apply a per-frame spectrum processor via WOLA analysis-synthesis.
std::vector< double >	MayaFlux::Kinesis::Discrete::spectral_filter (std::span< const double > src, double lo_hz, double hi_hz, double sample_rate, uint32_t window_size=1024, uint32_t hop_size=256)
	Hard bandpass filter: zero all bins outside [lo_hz, hi_hz].
std::vector< double >	MayaFlux::Kinesis::Discrete::spectral_invert (std::span< const double > src, uint32_t window_size=1024, uint32_t hop_size=256)
	Spectral phase inversion (conjugate all bins)
std::vector< double >	MayaFlux::Kinesis::Discrete::harmonic_enhance (std::span< const double > src, double enhancement_factor, uint32_t window_size=1024, uint32_t hop_size=256)
	Linear spectral tilt: scale each bin by a factor that rises linearly from 1 at bin 0 to enhancement_factor at the Nyquist bin.
std::vector< double >	MayaFlux::Kinesis::Discrete::spectral_gate (std::span< const double > src, double threshold_db, uint32_t window_size=1024, uint32_t hop_size=256)
	Hard spectral gate: zero bins whose magnitude is below the threshold.
std::vector< double >	MayaFlux::Kinesis::Discrete::phase_vocoder_stretch (std::span< const double > src, double stretch_factor, uint32_t window_size=2048, uint32_t analysis_hop=512)
	Time-stretch via phase vocoder analysis-synthesis.
std::vector< double >	MayaFlux::Kinesis::Discrete::pitch_shift (std::span< const double > src, double semitones, uint32_t window_size=2048, uint32_t analysis_hop=512)
	Pitch-shift by resampling around a phase vocoder stretch.
