Audio Editor is a digital audio workstation that runs in the page you are reading. It is built for the way studios work: an Edit window with a track list, waveforms on a timeline and edit modes, a Mix window with channel strips, faders, inserts and sends, offline processing for selected clips, breakpoint automation, markers, a tempo map and a MIDI editor with built-in instruments. The demo session that opens on the first visit shows what a finished arrangement looks like; replace it with your own tracks whenever you are ready.
Audio never leaves your device. Files you import are decoded in memory, playback goes through the browser's audio system, and bouncing a mix produces a download. There is no account and nothing to install; the first visit fetches about 6 MB, after which the browser cache makes the editor start in a moment.
What this audio editor can do
Bring in WAV, AIFF, FLAC, MP3, OGG, M4A and AAC files, or the audio of an MP4, MKV or WebM video, each onto its own track. Clips can be split, trimmed, moved, duplicated and nudged in Shuffle, Slip, Spot or Grid mode with the Smart, Trim, Grabber, Selector, Pencil and Zoom tools; fades and crossfades are drawn straight from the clip corners in several shapes, clip gain has its own line, and there is undo for everything. Tracks take ten inserts and ten sends, route to busses and aux inputs, and a master fader with peak-hold meters sits at the end of the chain. Automation for volume, pan, mute, sends and plug-in parameters can be drawn or recorded live in Write, Touch and Latch.
The built-in processors cover the essentials of a mix: seven-band and one-band EQ, compressor and limiter, expander and gate, de-esser, maximizer, a channel strip, room and plate reverbs, delays, chorus, flanger, phaser, saturation, lo-fi, pitch shift, time shift and a signal generator. Any of them also runs offline on a selection through the AudioSuite menu, which renders the result into the clip. Instrument tracks come with a subtractive synth, a drum synth and a sampler, and the piano-roll editor has quantize, transpose and a velocity lane. When the mix is done, Bounce Mix writes WAV, AIFF or FLAC at 16, 24 or 32-bit float with optional normalisation, and reports peak, true peak and integrated loudness.
When to use an online audio editor
Cleaning up a recording before publishing
A podcast episode or a voice memo needs the pauses cut, a gentle EQ, some compression and a consistent level. Put the file on a track, edit with the Trim and Selector tools, add the processors on the channel strip and bounce the result.
Mixing several tracks into one file
Voice, music bed and sound effects recorded separately belong on separate tracks with their own faders, fades and automation. The mixer balances them and the bounce renders a single stereo file.
Working with audio that must stay private
Interviews, drafts of unreleased music and meeting recordings should not sit on a server. Every operation, from decoding to bouncing, happens in the browser tab, so there is nothing to upload and nothing to delete afterwards.
How the editor runs in your browser
The workstation is compiled to WebAssembly and draws its interface on the graphics card through WebGPU or WebGL2, which is why it needs a desktop browser with one of the two. Sound is played through the browser's audio engine. Browsers only start audio after you interact with a page, so if you hear nothing at first, click into the editor once or press Space to start playback.
Import opens the browser's file picker and reads the file into memory; nothing is transmitted. The mix engine runs in parallel on your processor, so a session with a few dozen tracks and effects plays without stuttering on an ordinary laptop. Bouncing renders the selection, or the whole session when nothing is selected, with a progress bar, and the finished file is saved as a download.
How to use this tool
- Wait for the editor to load; the first visit downloads about 6 MB. A demo session opens so you can see the Edit window, the mixer and the transport straight away.
- Start a new session with File > New, then import your audio with File > Import > Audio. Each file lands on its own track in the timeline.
- Cut, trim and fade the clips, set levels and panning in the Mix window, add EQ, compression or reverb on the inserts and draw automation where a part needs to move.
- Choose File > Bounce Mix, pick WAV, AIFF or FLAC and the bit depth, tick Normalize if you want a consistent peak, and click Bounce. The file is saved to your Downloads folder.
Limitations
- A desktop browser with WebGL2 or WebGPU is required. Phones show a notice instead of the editor; a mouse and a keyboard make the edit tools usable.
- The first load is about 6 MB. Afterwards the editor starts from the browser cache.
- The browser version does not record from a microphone. Record with the site's Voice Recorder or another app, then import the file.
- Bounce writes WAV, AIFF or FLAC. For an MP3, run the bounced file through the Convert Audio tool afterwards.
- It is a capable editor for everyday work rather than a complete studio: third-party plug-ins, video playback and some advanced features of desktop workstations are not available in the browser, and sessions should be saved as files before the tab is closed.
