Variable rate controllable audio pitch shifter

Pitch shift node for WebAudioApi

Canonical phase vocoder (Bernsee/SMB) pitch shift

OLA (Overlap-Add) pitch shift — simplest stretch+resample baseline

Paulstretch-style randomized-phase pitch shift for textural blur

Peak-locked phase vocoder (Laroche-Dolson) pitch shift

Formant-preserving pitch shift via cepstral envelope re-imposition

WSOLA (Waveform-Similarity Overlap-Add) pitch shift — similarity-search OLA variant

Granular pitch shift — direct grain-read synthesis for signature textural sound

Spectral Modeling Synthesis (Serra/Smith) sinusoidal+residual pitch shift

Sampler-style pitch shift — sinc-interpolated fractional-stride resample (no time preservation)

Delay-line (harmonizer) pitch shift — dual crossfading taps sweeping a modulated delay window

Transient-aware phase vocoder pitch shift with attack preservation

PSOLA (Pitch-Synchronous Overlap-Add) pitch shift — pitch-synchronous grains for monophonic voice

Harmonic/Percussive Source Separation pitch shift — shifts harmonics, preserves transients

Hybrid pitch shift — runs phase-lock + WSOLA in parallel, crossfades by transient confidence

LPC source-filter pitch shift — repitched excitation residual through the unmodified all-pole vocal-tract filter

A pitch-shifting AudioBufferSourceNode built with Rubber Band

High-quality, low-latency pitch shifting and time stretching for Web Audio API using WebAssembly

Returns the next buffer/object in a stream's readable queue
