A complete browser-based audio editor with tracks, clips and layers

This online audio editor goes beyond one-section trimming. It provides a practical multitrack workspace for arranging voice, music and sound effects, cutting clips into pieces, moving audio across the timeline, stacking layers, controlling track balance and rendering a finished mix.

Cut, split and non-destructive trim

Split a selected clip at the playhead, drag either edge to reveal or hide source audio, and keep every piece independently editable.

Move and layer audio clips

Drag clips through time, drop them onto another track, overlap sound on multiple layers and create sequential arrangements on one track.

Per-clip processing

Rename, gain, fade, reverse and change the speed of individual clips without forcing the same setting onto the whole project.

Track mixing controls

Rename and reorder tracks, then set volume, stereo pan, mute and solo for narration, music, interviews, ambience or effects.

Precise timeline workflow

Zoom from an overview to detailed timing, enable snapping, choose a time grid and place the playhead by clicking the ruler or a track lane.

Local mix rendering

Render the complete arrangement to WAV or a browser-supported compressed format without a page-specific audio upload service.

How to edit, layer and mix audio online

The workflow supports simple trimming, podcast assembly, music-and-voice mixes, sound-effect layering, ringtone edits and short audio productions.

Add audio layersChoose one or more supported audio files. Each file can open as a separate track, or you can add a new clip to the selected track.
Choose an editing toolUse Select, Move, Cut, Trim or Add in the timeline toolbar. The active icon controls what a tap or drag does to a clip.
Cut and refine the editClick a clip with the Cut tool or use Split at Playhead, then copy, delete, rename, reverse, fade or change the selected clip.
Mix tracks and previewAdjust each track volume, pan, mute or solo controls, then play from any timeline position to review the complete mix.
Render and downloadChoose output quality, sample rate and channel settings, render the project, preview the result and download it with the CorrectionCopy filename.

Multitrack audio editor controls explained

Control	What it changes	Practical use
Select, Move, Cut, Trim and Add tools	Changes how taps, clicks and drags behave in the timeline.	Select safely, reposition layers, cut at a clicked point, trim clip edges or add audio at the playhead.
Clip move	Changes where a clip begins on the project timeline.	Arrange introductions, dialogue, music cues and effects in the intended order.
Clip edge trim	Changes the visible in or out point while preserving the original decoded source.	Remove unwanted speech, silence or endings and extend the clip again later.
Split at playhead	Creates two independently editable clips at the chosen project time.	Remove a middle mistake, separate phrases or apply different settings to each part.
Track volume and pan	Controls the level and stereo position of every clip assigned to that track.	Lower background music, centre speech or position effects across stereo output.
Clip gain and fades	Controls one clip independently and smooths its beginning or ending.	Balance inconsistent sections and create clean entrances, exits or overlaps.
Snap and grid	Rounds movements and trims to repeatable timing intervals.	Align clips to exact tenths, quarter seconds, seconds or broader timing points.

Common uses for layered audio editing

Podcast and interview assembly

Place an intro, spoken segments, music bed and closing on separate tracks. Split mistakes, move sections and balance narration against background audio.

Music clips and simple mashups

Trim useful parts from multiple songs or recordings, arrange them in sequence, overlap transitions and add clip fades.

Voice-over with sound effects

Keep narration on one layer and add alerts, ambience or effects on other tracks with independent volume and stereo placement.

Ringtones and social audio

Cut a concise section, combine an intro or spoken tag, normalize the final peak and export a compatible file for the intended platform.

Private no-upload multitrack audio editing

Source audio stays in the browser session

The page reads and decodes selected files locally. It does not send audio content, filenames, clips or project arrangements to a page-specific processing endpoint.

Rendered results remain local

The final mix is created in browser memory and exposed through a temporary download link. Clear Result or Reset releases that link.

No media permission is requested

The editor works with files selected by the user and does not request microphone, camera, screen or sensor access.

Reset clears the current project

Reset stops playback and export, releases decoded assets and removes tracks, clips, results and undo history from the current page.

Browser compatibility, performance and editing limitations

Audio decoding varies

A valid extension does not guarantee that every browser can decode the file's internal audio coding. WAV is a useful fallback when a source will not open.

Large layers consume memory

Every compressed file expands into uncompressed samples. Long stereo projects are more reliable on a computer with substantial available memory.

Speed changes pitch

Per-clip speed is intended for practical timing and creative effects. It does not preserve pitch like specialised studio processing.

Compressed rendering may be real time

WAV is rendered quickly after the mix is prepared. Some compressed formats may need to play the rendered project internally for its full duration.

Keep mobile pages active

Mobile systems can suspend memory-intensive pages when another app opens. Keep the editor visible during decoding and final rendering.

No plug-in effects chain

The editor focuses on reliable browser-native cutting, arrangement, fades, gain, speed, reverse, pan and mixing rather than studio plug-ins or advanced restoration.

Multitrack audio editing troubleshooting

A file will not open

Confirm that it is a genuine audio file and try a current browser. Convert unusual or unsupported coding to WAV before importing.

The project sounds distorted

Lower overlapping clip gains, track volumes or master gain. Enable final normalization and review the quality check before rendering.

A clip will not move exactly

Disable Snap for unrestricted movement or select a smaller grid such as 0.01 or 0.05 seconds.

The project becomes slow

Remove unused layers, shorten long source files, close other tabs and avoid loading more decoded audio than the device can comfortably hold.

Frequently asked questions about multitrack audio editing

Answers about cutting, splitting, moving, layering, mixing, track controls, clip fades, formats, privacy, mobile use and browser memory.

What can this multitrack audio editor do?

It can import multiple audio files, place them on layered tracks, move and trim clips, split at the playhead, duplicate or delete sections, change clip gain and speed, add fades, reverse clips, mix track volume and pan, and render one finished audio file.

Can I cut and join several audio files?

Yes. Add files as separate layers or place multiple clips on the same track, trim the unwanted parts, move clips into sequence and render the combined project.

Can I move an audio clip to another layer?

Yes. Drag a clip vertically and drop it on another track, or choose a destination from the selected clip controls.

How do I split audio into separate pieces?

Place the playhead inside a selected clip and choose Split at Playhead. The editor creates two independently movable and trimmable clips without changing the original decoded audio.

Can clips overlap?

Yes. Clips can overlap on different tracks or on the same track. Overlapping audio is mixed during playback and export.

Can I create audio layers for music, voice and sound effects?

Yes. Add separate tracks for narration, background music, interviews, ambience or effects, then adjust volume, pan, mute and solo controls for each layer.

Does the editor upload my audio?

No page-specific upload endpoint receives the audio. File reading, decoding, timeline editing, playback and rendering occur locally in the browser.

Which input formats can I add?

The file checker recognises MP3, WAV, M4A or MP4 audio, AAC, OGG, FLAC and WebM audio. Actual decoding support depends on the browser and device.

Which output formats are available?

WAV 16-bit, WAV 24-bit and WAV 32-bit float output are included. Compressed M4A, WebM or OGG choices appear only when the current browser reports that it can create them.

Can I export directly to MP3?

Direct MP3 encoding is not included in this browser-only editor. MP3 files can normally be imported, then exported as WAV or an available compressed format.

Can I trim a clip without deleting its hidden audio?

Yes. Dragging either clip edge changes the visible source range. The original decoded asset remains available, so you can extend the edge again within the source limits.

Can I add fade in and fade out to each clip?

Yes. Select a clip and set independent fade-in and fade-out durations. Fade lengths are automatically limited to fit the clip.

Can I adjust each clip volume separately?

Yes. Every clip has an individual gain control, while every track also has a separate volume control and the project has a master output gain.

What do mute and solo do?

Mute silences a track. Solo plays selected solo tracks while temporarily silencing tracks that are not soloed. Multiple tracks can be soloed together.

Can I pan tracks left or right?

Yes, when stereo output is selected and the browser provides stereo panning. Mono output combines the project into one channel.

Can I reverse only one clip?

Yes. Reverse is stored per clip, so other clips and tracks remain unchanged.

Can I change playback speed for one clip?

Yes. Each clip can use a speed from 0.5 to 2 times. This changes duration and pitch together rather than preserving pitch.

Does the editor support undo and redo?

Yes. Timeline moves, trims, splits, duplicates, deletions, track changes and inspector adjustments can be undone and redone during the current page session.

Can I snap clips to exact timing points?

Yes. Enable timeline snapping and choose a grid from hundredths of a second to several seconds. Disable snapping for unrestricted placement.

Can I preview the complete mix before exporting?

Yes. Set the playhead anywhere on the project and use Play. The preview schedules all audible clips with their track and clip settings.

Why can a large project use a lot of memory?

Compressed files expand into uncompressed audio samples after decoding. Multiple long stereo assets can therefore use substantially more memory than their original file sizes.

Does the editor work on mobile phones?

The controls are touch-friendly and the timeline uses an intentional internal horizontal scroller. Smaller projects are more reliable because mobile browsers have tighter memory and background-processing limits.

Why might compressed export take the full project duration?

Some browser-supported compressed formats are recorded in real time from the rendered mix. A five-minute project may therefore take about five minutes to create in that format.

How can I avoid clipping or distortion?

Lower clip, track or master gain when several clips overlap, or enable final peak normalization. Preview the mix and review the project quality check before rendering.

Can I make a podcast, mashup or ringtone?

Yes. The layered timeline is suitable for spoken clips, music beds, intros, sound effects, short mixes and ringtone-sized edits, subject to browser memory and format support.

What happens when I reset the editor?

Reset stops playback and rendering, releases result download links, clears decoded assets, tracks, clips and undo history, and returns to the empty project.
