Feature
Cleaner voice, in one switch
One switch takes out hiss, hum and room noise and sets your voice to the loudness Instagram and YouTube expect — no separate audio tool.
Phone audio is noisy and uneven, and quiet reels get skipped. Kool Captions cleans the voice and levels the volume so your reel sounds made-for-platform, and if you add music it ducks under your voice automatically — all alongside your captions.
What you get
- Removes hiss, hum and room noise with one switch.
- Sets loudness to what Instagram and YouTube expect, so nothing sounds quiet.
- Add music and it ducks under your voice automatically.
- Cleaner audio also means more accurate captions.
How it works
- Upload your video and pick your language. Paste your script if you have one.
- Style and fix. Every word is already timed — choose a look and fix anything.
- Export 720p, 1080p or 4K in your browser, or a plain .srt.

Questions
Will cleaning the audio change my voice?
It removes noise and evens the volume; it does not re-voice you. You can leave it off if you prefer the raw sound.
Does it add music?
You can add music from the library and it ducks under your voice automatically.
