Edit MP3, WAV and other audio files with sample-level accuracy. Remove unwanted parts, extract segments, or split long recordings into multiple files.
Combine multiple audio files into one track. Seamlessly join music, voice recordings, or sound clips with optional fade transitions.
Extract audio tracks from video files. Convert MP4, WebM and other video formats to MP3, WAV, or FLAC.
Convert between MP3, WAV, OGG, FLAC, AAC, MP4, AIFF and other formats. Control quality, bitrate, and sample rate.
Apply smooth fade-in and fade-out effects to avoid abrupt starts and endings.
Increase or decrease audio volume without distortion. Fine-tune loudness for music, speech, and recordings.
Normalize audio to a target volume level (e.g. -1 dB, -16 LUFS). Fix recordings that are too quiet.
Apply dynamic range compression to balance loud and quiet parts for a clear, professional sound.
Apply high-pass, low-pass, band-pass, or notch filters. Remove rumble, hum, hiss, or isolate specific frequency ranges.
Automatically detect and highlight silent parts. Clean up podcasts, interviews, voice recordings.
Split a long recording into parts and download every chapter as a separate file, bundled in a ZIP with an .m3u8 playlist. Ideal for audiobooks, lectures, and multi-part podcasts.
Export your editing session as a project file and reopen it later. All cuts, fades, volume, and effects are preserved.
Integrate audio editing into your website. Open audiocutter.online as a popup and send audio files via postMessage.
audiocutter.online is actively developed. Here is what landed lately — and what goes in next is up to you.
Selections, fragments and fades now snap to nearby edges, the playhead and the project end, with a guideline showing what you are snapping to. Hold Alt to place something freely.
The editor can now run inside an iframe as well as a popup. Send audio or a whole project in over postMessage, let your users edit it, and get the result back — no server required.
