pulp::signal::FreezeHoldReferenceTiming Struct Reference

Time-based FreezeHold timing that reproduces the frame-count defaults (8 capture frames, 6 crossfade frames, 0.015 rad/frame walk) at the reference geometry they were tuned for: a 512-sample analysis hop at 48 kHz (RealtimePitchTimeProcessor's quality mode, 4096/512). More...
