Speed & Pitch Shifting Frequently Asked Questions
Learn how client-side Web Audio resampling works.
How do I create Nightcore or Slowed + Reverb audio tracks?
Upload your music or vocal track, adjust the playback speed and pitch slider (0.8x for Slowed mood, 1.25x for Nightcore), listen to real-time audio playback preview, then click "Export Modified Audio" to download the re-rendered WAV track.
Can I speed up lectures or podcast recordings to save time?
Yes! You can speed up audio recordings up to 2.0x to transcribe or listen to study material in half the time without needing an external media player.
Is my audio uploaded or compressed with lossy quality?
All audio processing occurs locally through the browser Web Audio API. When exported, the audio is rendered using 16-bit uncompressed linear PCM (WAV), preserving full fidelity.
