CBCOM Audio Studio
All our audio tools in one workspace. Load one or more tracks — each gets its own sound bar. Select a stretch and edit it directly: volume, pitch, speed, reverse, cut, bass & treble, fades. Add extra sounds or record your voice, polish each take on its own, then place it into the mix. Everything runs in your browser; nothing is uploaded.
How it works
Every main file is its own sound bar, and in the preview they all play together. Drag on a bar to select a stretch, then use the Edit island below: volume, pitch, speed, reverse, cut — the edit is applied immediately, press ▶ to hear it and ↩ Undo to take it back. The Equalizer island adds bass, treble and fades. Your extra sounds and microphone recordings sit in their own small lists; open one to polish it, then push it in between, mix it over the original or glue it to the end. When everything sounds right, render the preview — that is your free final check before downloading the MP3.
How do I cut and paste a part?
Select the stretch and press ✂ Cut — it disappears from the bar right away. Want to paste it somewhere else? Press 📋 Copy first: the stretch lands in the Sounds list, where you can polish it and then place it at any exact time, mixed over the original, or at the end.
Can I edit a recording before it lands in my project?
Yes — that is the whole idea. A microphone take or an added file first sits below as its own sound bar. Trim it to the good part, fix its volume or pitch, listen with ▶ — and only when it is right, place it into the main audio.
Does my audio get uploaded?
No. Decoding, editing, mixing and MP3 encoding all happen inside your browser — your audio never leaves your device. Even the speech and speaker detection run locally.
Getting more out of the Audio Studio
The quickest way to understand the studio is this: every sound bar is a piece of material, and the preview is what those materials sound like together. Nothing is destructive to the file on your disk — the edits live in your browser until you render, so you can be blunt with an experiment and undo your way back. Two habits make everything else easier. Work on one bar at a time and press S to solo it, so you hear exactly what you are editing. And render the preview often: it is free, it uses the same engine as the download, and it is the only honest check that the mix actually works.
A voice over music
Load the music as your first bar. Bring the voice in as a second bar rather than as a placed sound — a bar of its own can be soloed, trimmed and levelled independently. Set the music to roughly a third of the voice with the volume slider, and add a fade at the start and the end so it does not begin and stop abruptly. If the music still fights the words, take a little out of the middle of the spectrum with the MID knob instead of turning everything down. Preview, adjust, and only then download.
Cleaning up a rough recording
A phone or laptop recording usually needs three things, in this order. Trim the silence and throat-clearing at both ends — select and cut. Reduce noise to take out the steady hiss of the room or the microphone; it works on a constant background, not on a passing car. Then normalise, which lifts the whole take to a healthy level without you guessing at a number. Doing it in the other order makes the noise louder before you remove it. If a few words are much quieter than the rest, select just those and raise them on their own rather than pushing the whole take.
