What Is an Audio Cutter?
An audio cutter lets you select a specific part of a recording, song, voice note, or podcast and export only that section. This editor decodes and processes your media locally, so your source file stays on your device.
Use the waveform for visual selection or enter exact timestamps in minutes and seconds. You can preview the selected range, add short fades, change output gain, and listen to the processed result before downloading it.
How to Cut Audio or Create a Ringtone
Choose a supported media file
Add an MP3, WAV, M4A, OGG, AAC, FLAC, WebM, MP4, or MOV file. Codec support depends on the browser and the audio track stored inside the file.
Select your clip using the waveform
Drag the cyan and red handles on the waveform to define your start and end points, or type exact times in the input fields. Use the preset buttons for common ringtone lengths (15s, 30s, etc.).
Preview your selection
Click Play to hear only the selected section. Adjust the handles until it sounds exactly right. The yellow playhead shows your current position.
Add effects (optional)
Use Fade In for a smooth start, Fade Out for a clean ending, and Output Gain when the selected audio needs a level adjustment.
Process, preview, and download
Choose MP3, WAV, OGG, or M4A, process the clip, listen to the exact exported result, and download it. Device-specific ringtone setup may require additional steps.

After trimming, use the Audio Speed Changer to adjust tempo or pitch, the Volume Booster for normalization and loudness control, or the Audio Converter for another file format. To arrange several finished clips into one file, continue with the Audio Joiner.
Frequently Asked Questions
Format and performance note: Input support depends on the codecs available in your browser. WAV output avoids an additional lossy encoding step; MP3, OGG, and M4A require local WebAssembly encoding. For stability, the editor limits files to 25 MB and 15 minutes on mobile, or 75 MB and 30 minutes on desktop. Only edit media you have permission to use.
