Make audio faster or slower without the chipmunk voice
Processed in your browser. Nothing is uploaded. Updated on 24 Oct 2026.Drop the audio and press a speed: 1.25×, 1.5× or 2× to get through a long recording, or 0.75× to hear every word. The pitch is kept, so voices sound like themselves instead of cartoon characters, and you can speed up only one stretch by dragging across it first. The result saves as M4A or WAV, and nothing is uploaded.
Drop the audio file onto the page; Keep the pitch is already on, so voices sound normal at any speed.
With nothing selected, the speed applies to the whole audio; drag across a stretch to change only that part.
Pick 1.25×, 1.5×, 1.75× or 2× under Speed, or type an Other speed such as 1.3 and press Apply.
Press Play to check it, then Download M4A or switch Save as to WAV first.
The Audio Editor puts the everyday audio jobs on one timeline: joining several recordings, cutting out the parts you do not want, and speeding up a stretch or the whole thing.
Cutting and deleting. Click to place the playhead, or drag across the waveform to select a stretch. Delete removes it and closes the gap; Keep only this throws away everything else; Split here cuts a piece in two at the playhead so each half can be moved or sped up on its own. Every cut gets a five-millisecond fade at each side, too short to hear as a fade but long enough that no join ever clicks. Undo steps back through the last fifty edits.
Speed. Select a stretch and choose a speed, or choose one with nothing selected to change the whole audio: 0.5×, 0.75×, 1.25×, 1.5×, 2×, or any speed from 0.25× to 4×. With Keep the pitch on, the sound is stretched rather than played faster, so a voice at 1.5× still sounds like the same person. Switch it off for the tape effect, where faster also means higher.

Drop the file and choose a speed such as 1.25×, 1.5× or 2× with Keep the pitch switched on. The audio is stretched in time rather than played faster, so voices keep their normal pitch. Any speed from 0.25× to 4× can be typed in as well.
Yes. Drag across that stretch on the waveform to select it, then choose the speed. Only the selected part changes; the rest plays as recorded. Different parts can have different speeds, and each sped-up piece shows its speed on the timeline.
Drag across the part on the waveform and press Delete, or the Delete key. The two sides join with a five-millisecond fade so there is no click. Ctrl+Z undoes the last edit, up to fifty steps back.
Yes. Every file you drop is added to the end of one timeline. Cut, delete or speed up across the joins as if it were one recording, and move any piece earlier or later. Files with different sample rates are matched automatically.
