iZotope Ozone 11

DAW-based mastering

Ozone is the obvious mastering suite if you want to work inside a DAW. Master Assistant gets you close fast, and the included modules cover loudness, tonal balance, and stereo work without leaving your session. Voice-only podcasts probably don't need this much firepower.

Ozone is iZotope's mastering plugin suite and the default choice for music producers who master in the DAW. The headline feature is Master Assistant: it analyses a finished mix and proposes a mastering chain tailored to the genre, source loudness, and tonal balance, including EQ moves, multiband dynamics, stereo widening, and a final limiter. For podcasters with a serious post-production workflow, Ozone makes the most sense on shows that blend voice and music, or scripted audio drama where the master genuinely benefits from a real engineer's chain. For talking-head two-mic interviews, the cheaper path is loudness normalisation plus a single broadband compressor; you do not need a multiband-plus-imager-plus-limiter chain on a Tuesday conversation podcast. The tier choice matters. Elements is the cheapest entry, Standard is the sweet spot for most users, and Advanced unlocks the deep tools, including reference matching and the Codec Preview that lets you audition how a master will sound after Spotify or Apple Podcasts compresses it. iZotope runs sales constantly, so list price is mostly fiction. Wait for one and pick the tier whose surface area you'll actually use. For voice-only podcast workflows, RX Elements is the more useful iZotope tool; Ozone is the right choice when music or scored content is the production focus.
