💡 Tip: Changing pitch also changes duration. To keep the original feel, reduce speed slightly when pitching up, or increase speed when pitching down.
Basic Pitch & Speed
Pitch - Customize the pitch of your audio with precision. Adjust the exact number of semitones (from -12 to +12) to change the vocal scale.
Speed - Adjust the playback speed of your audio. Modify speed multiplier (ranging from 0.5x to 1.5x) to either slow down or speed up your audio playback rate.
Advanced Gain Control
Output Trim dB - Optimize the decibel level of your output. Adjust trim level to prevent clipping and balance volume after pitching or speeding up your file, ensuring maximum sound clarity.

Audio Pitch & Speed Changer - Slow Down or Speed Up Audio
Adjust pitch and speed independently or simultaneously. Perfect for transcribing music, learning instruments, or shifting key.
Changing the tempo or key of a song is invaluable for musicians learning complex solos, transcribers writing down speech, or vocalists shifting tracks to fit their range.
Independent Speed & Pitch Control
Traditionally, altering speed also altered pitch (and vice versa). Modern digital signal processing allows us to unlink them: - **Tempo Control**: Speed up or slow down playback from 0.5x to 2.0x without changing the pitch, perfect for studying rapid music passages. - **Pitch Control**: Transpose the key of the song up or down in semitones while maintaining the original speed, allowing singers to match their key.
Vinyl Mode (Linked Control)
If you prefer the vintage effect of speeding up a tape or record, you can enable linked mode. In this mode, speeding up the track naturally raises the pitch, simulating physical turntable acceleration.
100% Client-Side Transposition
Our pitch-speed changer uses advanced phase vocoder techniques client-side to stretch or shift the audio buffer without server assistance. It provides real-time live preview playback, ensuring a quick and interactive editing workflow.
