Edit audio on a waveform: cut, insert silence, arrange clips, mix tracks and apply effects. Listen to your edits, then export the whole project or a selected range.
Click the waveform to set the playhead. Drag across it to select a range, or enter exact times above.
Preview an effect before applying it. Applied effects enter the undo history; changing export settings does not alter your edits.
Export downloads automatically when ready. Bitrate affects compressed formats; tag support depends on the chosen format.
Use the waveform to remove mistakes from recordings, add pauses, rearrange passages or build a mix with speech and music. Apply volume, fades, speed, pitch, noise reduction, equalization and other effects to the selected range, a track or the project. Keep editing with undo and redo, then download the finished audio.
Select the range and use Delete selection. Later clips on that track move forward to close the gap. If several tracks must stay synchronized, enable moving later clips on all tracks. Keep selection does the opposite: it removes the surrounding audio.
Insert silence adds a gap of the chosen duration and shifts later clips. Silence selection replaces the selected sound with silence without changing its duration. By default, these actions affect the current track; inserting silence can also apply to all tracks. When you edit only the current track, other tracks remain audible unless you mute or edit them too.
Yes. Select the passage and choose Selected range as the effect target. Current track affects the active track, while Entire project processes the mix. Preview before applying, especially for denoise, compression and equalization: stronger settings may also change the sound you want to keep.
Add the music on another track and mark that track as background music. Set its volume, start delay and play count, then enable Lower music during speech. Listen to the mixed result to check that speech remains clear and music transitions sound natural.
Playback uses the current project, including edited clips, track volume and mixing. Preview effect lets you listen before committing a new effect. Some processing needs time to prepare; wait for it to finish before comparing or applying the result.
Undo and redo are available while editing. Save project keeps the audio and arrangement in a project file that you can open later. Local drafts depend on browser storage, so use a project file for work you need to keep; exporting audio creates a finished file for listening, rather than an editable project.
Choose MP3, WAV, M4A, AAC, OGG, Opus, FLAC, AIFF or raw PCM. Export the full project, the selected range, or the current track’s individual audio clips in a ZIP. Compressed formats use a bitrate setting; raw PCM has no file header, so its sample rate and channels must be known when opening it elsewhere.

Trim, join or split recordings, remove silence or noise, and adjust volume, speed, pitch or channels.
