This skill addresses the degradation and phase artifacts typically associated with offline time-stretching, pitch-shifting, and varispeed processing in audio production.
Use the stretch skill to process the input file in.wav to out.wav with a time ratio of 1.5 and the clean character mode.

Offline time-stretching with transient-aware processing preserves percussive attacks by using verbatim transient relocation. This ensures drum hits remain sharp and punchy while tonal material is processed, avoiding the phase-smearing common in standard vocoders.
Pitch-shifting offline without phase artifacts is achieved using phase-locked spectral processing. This method maintains signal coherence and delivers artifact-free audio rendering, satisfying requirements for bit-identical offline compilation in production environments.
Varispeed processing provides tape-like pitch and tempo manipulation by coupling speed and pitch adjustments together. This character-based approach offers an alternative to clean phase-vocoder modes, delivering vintage-style audio signal modification.
Phase-locked spectral processing works by maintaining phase coherence across frequency bins during time-stretching. This technique prevents the phase artifacts and signal degradation typically associated with offline time-stretching, ensuring high-fidelity audio rendering.
Offline audio time-stretching operates using a C++20 core engine, requiring a compatible C++20 build environment. It performs bit-identical offline compilation and artifact-free rendering without external dependencies, ensuring self-contained audio signal processing.
