Algorithm

enum class zrythm::dsp::StretchOptions::Algorithm : std::uint8_t

strong

Material-aware timestretch algorithm.

• Beats: rhythmic content (drums, percussion). Uses R2 engine with percussive detection and crisp transients.
• Monophonic: solo voice / single melody. Uses R2 engine with soft detection and smooth transients.
• Polyphonic: complex mixtures (default). Uses R3 (Finer) engine for highest quality.
• Repitch: varispeed — pitch follows tempo (tape-style). Not yet implemented; RubberBand reports it as unsupported, so the NVI layer rejects requests for it. It will be provided by a future Resampler engine (TimeStretchEngineId::Resampler).
