WSOLA time stretching — time-domain, low CPU, great for speech

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

Time stretching — umbrella for @audio/stretch-* atoms (WSOLA, phase vocoder variants, PaulStretch, PSOLA, SMS)

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

Canonical pitch-shifting algorithms: phase vocoder, peak-locked, transient-aware, PSOLA, WSOLA, granular, PaulStretch, SMS, HPSS, formant, sampler, hybrid

Web Audio API modules with WSOLA time-stretching, chunk-based streaming, and waveform extraction

Phase vocoder time-stretch stage for SoundTouchJS — a StretchPipe implementation using FFT-based phase accumulation.

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

Kali is used for realtime time-stretching and pitch shifting in Javascript. It can change Tempo and Pitch independently.
