Dolby.io Media Enhance

API-based voice enhance

Dolby.io brings Dolby's broadcast audio engineering chops to a simple API and a small web tool. Drop in a noisy recording, get back a cleaned and leveled file that genuinely sounds broadcast-ready. Useful for teams that want to automate cleanup at scale.

Dolby.io is Dolby's developer platform that exposes the company's media engineering work via APIs and a small set of hosted web tools. The Media Enhance product takes a voice recording and applies Dolby's noise reduction, hum removal, sibilance taming, and loudness normalisation, returning a file that sounds like it came out of a real broadcast studio. For podcasters, the appeal is two-fold: the audio output is consistently good, often noticeably better than the free Auphonic equivalent on tough material, and the API means you can wire enhancement into a production pipeline rather than processing episodes by hand. If you run an in-house show factory or a hosting platform, the per-minute economics work out faster than you'd expect. The tradeoff is control. You don't pick a noise floor target, you don't choose which sibilance band to attack, you don't get to dial back enhancement strength beyond a single parameter. Dolby's defaults are good, but they are defaults. For one-off episodes where you want to babysit each parameter, Auphonic's web UI gives more visibility. For automated cleanup of hundreds of files a month, Dolby.io is the better fit. The free tier covers initial experimentation, and pricing moves to usage-based after that. One caveat: Dolby.io is positioned as a developer platform first, with the web tool secondary, so factor in engineering time when budgeting.
