SamplePitcher FAQ

Client-Side Web Audio Pitch Shifter Questions

How does SamplePitcher change sample key without changing speed?

SamplePitcher uses browser-based Digital Signal Processing (DSP) to separate pitch adjustment from audio duration, allowing you to transpose loops by semitones while locking the original tempo.

Are my audio files uploaded to a remote server?

No. SamplePitcher runs entirely client-side using the Web Audio API and local DSP. Your audio files stay 100% private inside your browser memory and are never uploaded to any cloud server.

What audio formats are supported?

SamplePitcher accepts WAV, MP3, AIFF, FLAC, and OGG formats, exporting clean, uncompressed WAV files individually or packaged in a single ZIP archive.
