How to edit audio online
1
Open a file
The waveform loads so you can play, zoom, and drag a selection.
2
Edit and add filters
Crop, cut, or silence the selection. Add EQ, dynamics, space, pitch, or tempo and reorder them.
3
Master and export
Set gain, loudness, and MP3 or WAV. The file downloads when the render is ready.
An audio studio in the browser
MP3Extra Audio Studio is a multitrack editor for producers. Add tracks, line them up on a timeline, and balance them with volume, pan, mute, and solo. Edit each track’s waveform, run a per-track filter rack, then the master bus mixes everything with a limiter. Preview while you work; the mix is rendered on the server and then deleted.
What you can edit
Multitrack timeline
Layer up to 12 tracks, set each one’s start time, volume, pan, mute, and solo, and edit its waveform.
Filter rack
Add EQ, high-pass, low-pass, compressor, limiter, gate, denoise, chorus, or flanger. Bypass or reorder any filter.
Space, pitch, and tempo
Reverb, delay, stereo width, 8D, pitch shift, and tempo that can keep the pitch.
Master bus
Output gain, even loudness, stereo or mono, and a limiter on every export.
Preview
Hear the track in the browser while you edit. The downloaded file is the full server render.
Export
MP3 at 128, 192, or 320 kbps, or uncompressed WAV, with a title and artist tag.
Why use this studio
Mix multiple tracks on a timeline and edit each one the way a desktop studio does.
Add EQ, compression, reverb, pitch, and tempo in any order, then bypass or reorder them.

Export quality
MP3 defaults to 192 kbps, with 128 and 320 available. WAV is uncompressed 16-bit. Uploads can be up to 80 MB and 60 minutes. Repeats are limited to four so the result stays within that length. Edited files are deleted after processing.
Audio studio questions
Is the audio studio free?
Yes. Upload, edit, and download without an account or an app.
Which files can I edit?
MP3, WAV, FLAC, M4A, AAC, OGG, OPUS, WMA, and common video files that contain audio, up to 80 MB and 60 minutes.
How do I mix several tracks?
Add a track for each file. Set its start time, volume, and pan, mute or solo tracks while you work, then Export mixes them into one file.
Can I master a track?
Yes. Add EQ or a compressor in the rack, then use Master for gain, even loudness, and the limiter. Export MP3 or WAV.
Does this replace the cutter or the key changer?
The studio trims, shifts pitch, and mixes effects in one pass. The cutter, key changer, part-effects editor, and converter stay available when you only need that one job.
Are my files kept?
No. The upload and the edited file are deleted from the server after processing.
Can I make a voice sound like a phone call?
Yes. Add the Phone filter, then set the master channels to Mono.
Why did an edit fail?
The trim may start after the file ends, the result may be longer than 60 minutes, or the file may have no audio track. Shorten the trim or the repeats and try again.
