How to use Audio Studio
- 1Add one or more audio files — each arrives as a clip on the timeline
- 2Trim, reorder and set the level of each clip, and choose how they join
- 3Stack master effects: normalise, fade, reverse, sample rate, channels
- 4Adjust master volume and speed, with pitch locked or free
- 5Play the whole project, then export in the format you need
What Audio Studio does
Most browser audio tools do one thing to one file. That works until an edit needs two steps — trim, then normalise, then fade — at which point you are exporting an intermediate file and loading it back in, re-encoding at every stage and losing quality each time.
A studio avoids that by keeping the edit as a description rather than a result. Clips, junctions and effects are stored as a project and applied in one pass whenever the preview is rebuilt, so nothing is ever committed until you export. Turning an effect off restores exactly what came before it, because the audio is rebuilt from the original samples every time rather than edited in place.
When to use it
- A podcast episode from parts
- Intro music, the recorded conversation and an outro, joined with crossfades, normalised to a consistent level and faded at both ends — assembled and exported in one pass.
- Rescuing a quiet recording
- Normalise lifts the loudest moment to a set ceiling and brings everything up with it. For a recording made too far from the microphone, that alone often makes it usable.
- Voice notes ready to send
- Trim the silence, fold to mono and drop the sample rate to 16 kHz. Speech survives that intact and the file becomes a fraction of the size.
- Speeding up a lecture
- The master speed control with pitch locked plays a recording faster without the chipmunk effect, and exports at the new pace so it stays that way on any player.
Audio Studio settings explained
- Normalise
- Finds the loudest peak in the finished mix and raises everything so that peak sits at a target level, −1 dB by default. It changes the level, not the dynamics — quiet passages stay proportionally quiet.
- Fade
- Eases the whole project in from silence and out to it, one second in and two out by default. Applied to the master, after clips are joined, so it fades the finished piece rather than any single clip.
- Reverse
- Plays the entire mix backwards. Applied after fades, which means a fade-in becomes a fade-out — the order of the chain is fixed and this is one of the places you can hear it.
- Sample rate
- Resamples the finished mix. 44100 Hz is CD standard and the default; 16000 is ample for speech and much smaller; 48000 matches video. Applied late so every clip is already at a common rate.
- Channels
- Folds the mix to mono or spreads it to stereo. Mono roughly halves the exported size and costs nothing on a voice recording, where both channels usually carry the same signal.
- Master volume and speed
- Overall gain in decibels, and playback speed with an option to keep the original pitch. With pitch unlocked, speeding up raises the pitch as a tape machine would; locked, only the tempo changes.
- Undo and redo
- One step per gesture, not per pixel. Dragging a slider from one end to the other is a single undo, because the project is committed when you release rather than on every intermediate value.
Where each effect sits in the chain
| Order | Effect | Why it sits there |
|---|---|---|
| 1 | Normalise | Needs the whole joined mix to find the true peak |
| 2 | Fade | Shapes the normalised mix, not the raw clips |
| 3 | Reverse | Applied after fades, so in and out swap over |
| 4 | Sample rate | One resample of the finished audio, not per clip |
| 5 | Channels | Last, so nothing downstream re-splits the mix |
Limits and what to expect
- 20 clips per project, 150 MB per file and 400 MB across the project.
- Every clip is held decoded in memory, so a long project uses far more RAM than the file sizes imply.
- The effect order is fixed and cannot be rearranged — only enabled and disabled.
- There is no equaliser, compressor or noise reduction; this is arrangement and level work, not mastering.
- Projects are not saved. Closing the tab discards the arrangement along with the audio.
Troubleshooting
- Normalise did not make it much louder
- Normalising works from the single loudest peak. One brief spike — a cough, a bump on the microphone — sets the ceiling for the whole recording. Trim the spike out first, then normalise again.
- Speeding up made everyone sound strange
- Keep pitch was off, so the audio is resampled like a tape played fast and the pitch rises with the tempo. Turn it on to change speed alone, which is what you want for a lecture or podcast.
- The fade is at the wrong end
- Reverse is applied after fade in the fixed chain, so enabling both puts your fade-in at the end of the result. Swap the fade values to compensate, or reverse the individual clip instead of the master.
- The project became sluggish
- Each preview rebuild re-applies the whole chain to the whole project. Disable effects you are not currently judging while you arrange clips, then switch them back on for the final listen.
Your files and your privacy
The entire project — decoding, arranging, every effect and the final export — runs inside the browser tab on your own device. Nothing is uploaded, no project state is stored on a server, and no account exists to attach it to. That also means nothing is recoverable after the tab closes, so export before you leave.
What to use next
FAQ
Is this a replacement for Audacity or a DAW?
No, and it is not trying to be. There is no equaliser, compressor, noise reduction or plugin support. What it does cover is the work most people actually need — arranging clips, matching levels, crossfading, fading and exporting — without an install, an account or an upload.
Does editing reduce quality?
The edit itself does not. Clips are decoded to full-precision samples and every effect is applied to those, once, when the project is rendered — there is no intermediate re-encode. Quality is decided entirely by the export format you choose at the end.
Can I change the order the effects apply in?
No. The chain is fixed: normalise, fade, reverse, sample rate, channels. That order is chosen so each effect sees what it needs — normalise needs the joined mix to find the true peak, and resampling once at the end is cleaner than resampling every clip.
How do I speed up audio without changing the pitch?
Use the master speed control with keep pitch enabled. Without it, the audio is resampled and pitch rises with tempo, like a tape played fast. With it, only the timing changes, which is what makes a lecture at 1.5× still sound like the person speaking.
Is my project saved if I close the tab?
No. Everything lives in the tab's memory and is discarded when it closes. That is the direct consequence of nothing being uploaded — there is no server holding a copy — so export the result before you navigate away.
How many clips can I work with?
Up to 20, within 400 MB. Because decoded audio is uncompressed in memory, a handful of long recordings will reach the practical limit well before twenty short ones.
