Audio Workspace
Drop your tracks and run a pipeline across all of them (convert format, trim, normalize loudness, adjust volume and add fades) entirely in your browser, with no uploads.
All processing happens in your browser and your files are never uploaded.
Four steps, one canvas
No sign-up, no uploads, build a pipeline and run it across your files.
- 1
Add your audio
Drag in one track or a batch of MP3, WAV, OGG, FLAC, M4A or AAC files. They load with an inline player. Nothing is uploaded.
- 2
Build a pipeline
Stack operations like trim → normalize → convert. Tune each step's options live and reorder them however you like.
- 3
Apply to one or all
Run a step on the selected track or apply the whole pipeline across every file at once, with per-file undo and redo.
- 4
Download the results
Export a single processed track, or grab the whole batch as a ZIP, all encoded locally in your browser.
Built for real, chained work
Private by design
Audio is decoded and re-encoded in your browser with ffmpeg.wasm. No uploads, no server copies.
Real pipelines
Chain multiple operations and apply them across a whole batch. Not one tool at a time.
Honest processing
The ffmpeg WASM core loads once on first use, so the very first operation is slower. After that it stays cached.
Undo anything
Every step is reversible per track with keyboard undo/redo: experiment freely.
Frequently asked questions
Prefer a single tool?
Audio Format Converter
Convert audio between any formats in your browser, MP3, WAV, OGG, FLAC, M4A and AAC, both ways. Drop a file, choose a target and quality, preview the waveform, then download. Everything runs locally. Nothing is uploaded.
Audio Trimmer
Trim audio in your browser with a real waveform: drop an MP3, WAV, M4A or OGG, drag a selection to keep exactly the part you want, preview it, then download a lossless WAV or a compact MP3. Sample-accurate and 100% private. Nothing is uploaded.
Audio Normalizer
Normalize audio volume in your browser: lift a too-quiet recording to a clean target level with peak or RMS normalisation, compare the before/after waveform, then download WAV or MP3. Nothing is uploaded.
MP3 Converter
Convert any audio to MP3 in your browser, WAV, M4A, AAC, OGG, FLAC and more to a clean, universally-playable MP3 with a bitrate you choose. Preview the waveform, encode locally with lamejs, then download. Nothing is uploaded.
Audio Volume Booster
Boost audio volume in your browser: push a too-quiet MP3, WAV or M4A louder by an exact dB amount with built-in clip protection, or turn a hot track down. See the headroom, preview the result, then download WAV or MP3. Nothing is uploaded.
Audio Fade In / Out
Add a smooth fade-in and fade-out to audio in your browser with a live waveform. Drop an MP3, WAV, M4A or OGG, set the fade lengths, watch the volume ramp painted right on the wave, preview it, then download a lossless WAV or a compact MP3. Sample-accurate and 100% private. Nothing is uploaded.
