Pitch Shift Samples Without Changing Tempo
PITCH SHIFT lets you repitch any audio sample — vocals, loops, one-shots — while keeping the original tempo and duration intact. Uses native browser resampling combined with overlap-add time-stretching for fast, clean pitch shifting.
The CALC tab is a quick-reference tool for calculating the exact semitone shift needed to match a sample from one BPM to another. Formula: semitones = 12 × log₂(target ÷ original).
