Manual cuts; set the export range separately from the sections you delete.Open tool 03

Speed up or slow down audio

Speed Changer

Change the playback rate from 0.75× to 1.5×. Preview the voice at the selected speed and export MP3.

Duration and pitch change together; this does not preserve the original pitch.Open tool 05

Make audio louder or quieter

Volume Changer

Apply a fixed gain and check the predicted peak. Listen to loud and quiet passages before exporting.

−12 to +12 dB; increasing gain also raises background noise.Open tool 06

Need a different audio format?

Audio converter

Convert one audio file to MP3, WAV, FLAC, M4A, AAC or OGG/Opus for the next app or listener.

From a recording to a file you can use

  1. 01

    Choose a file

    Use a recording you have the rights to edit. The browser needs to decode its audio, so the extension alone does not guarantee it will open.

  2. 02

    Adjust one thing

    Choose cuts, a playback rate, a gain or an output format. Check what that tool changes before combining several edits.

  3. 03

    Review the result

    Listen near the cuts and at both ends of the export range. Check the selected track, expected duration and peaks after a gain change.

  4. 04

    Export a new file

    Download the result and open it in the app where you will use it. Keep the original recording for later revisions.

Your file

Know what to expect.

01

Local media, website requests

Your media is processed in the browser. The website still loads its own resources and uses website analytics; that is separate from uploading your recording for processing.

02

A new file, not a saved project

Export creates a new file and keeps the source unchanged. Refreshing or closing the tab ends the editing session. Download your result before leaving; the website does not save a project for your next visit.

03

Choose by the actual task

These tools do not clean background noise, identify spoken filler words or preserve video pictures. Speed changes also change pitch. Use the tool that fits the result you need.

Before you start

Common questions.

Do I need an account?

No. The six AudioCut tools are free to use and do not require an account.

Are my files uploaded?

No. The current tools process supported media in this browser. The selected file, filename, waveform and result are not sent to AudioCut.

Which files work?

MP3, WAV, M4A, AAC, FLAC, OGG and Opus are supported, along with MP4, MOV and WebM when the browser can decode their audio track.

Can I edit the picture in a video?

No. A video is used as an audio source. AudioCut exports an MP3 and does not edit the picture.

Will the original change?

No. The source file stays unchanged and the tool creates a separate audio result.

Can I use AudioCut on a phone?

Yes, in a modern browser. Codec support and device memory still affect which files work, so test an important edit with a short copy first.
