BandLab Mastering

Free mastering passes

BandLab Mastering is free and unlimited, which is genuinely rare in this category. Quality lands a step behind paid services on tricky material, but it's impressive for the price. Run a test before paying anyone.

BandLab is a social music platform that also owns Cakewalk, and its Mastering service is a free AI mastering pass bundled inside the platform. The pitch is simple: make an account, upload a stereo mix, pick between three style presets, and download a mastered file. You can re-master as many times as you want, switch styles, compare against the original, and download in WAV or MP3. There is no per-track fee, no subscription, and no watermark on the output. The catch, naturally, is control. You don't pick a target LUFS, you don't see a chain, you don't get reference matching, and you can't tweak EQ moves. For podcasters whose mixes are already close, that's fine. For tricky material like a noisy field recording or a heavily-processed music podcast, you'll hear the limits and probably want LANDR or Ozone. The honest move is to run a typical episode through BandLab first, listen on a few sets of speakers and headphones, and only pay for something more sophisticated if you can hear a meaningful gap. Many podcasters can't, and pocket the savings. BandLab also bundles a free DAW and a community feed, neither of which most podcasters need, but the mastering tool stands on its own as a free utility.
