BandLab Mastering

Mastering is the final polish before publishing. For a speech podcast, try a free preset, then check the loudness of the result: if it already sits where you want, you may not need anything paid.

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 one of the four free presets (Universal, Fire, Clarity, Tape; four more come with a paid Membership), 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. On the free presets there is no per-track fee and no subscription. The catch, naturally, is control.

You don't pick a target LUFS or see a chain, and the intensity control, mastering EQ and reference mastering are paid Membership features. 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.
