Auphonic

Auphonic is an automated audio post-production platform that handles the engineering side of podcasting without requiring you to know what compressor ratios or true peak limits actually mean. You upload a file, define your target loudness (typical podcast values are -16 LUFS stereo or -19 LUFS mono), true peak limit, and max LRA, and Auphonic does the rest: intelligent leveling between speakers, noise and reverb reduction, filler word detection ('um' and 'ah' removal), silence trimming, and multilingual speech-to-text.

Output meets broadcast loudness standards and platform compliance specs automatically. Pricing is flexible — free tier offers 2 hours/month of processing, subscriptions start at $11/mo for 9 hours and scale to $119/mo for 100 hours, and one-time credit packs ($12 for 9 hours) work for occasional users.

Auphonic also auto-publishes processed files to YouTube, Libsyn, Podbean, SoundCloud, and Facebook in a single flow, killing the post-production handoff most podcasters do manually. The platform has been around since the early 2010s and remains the de facto gold standard for podcast mastering automation.

Strengths: the loudness math is genuinely correct (matters for compliance), the intelligent leveler beats most amateur DAW work, and the automation removes the most tedious parts of post. Weaknesses: web UI feels dated next to Descript or Riverside, filler word removal lags Descript in accuracy, and there's no editing interface — Auphonic is mastering and assembly, not full production. Best for podcasters who already record cleanly and want broadcast output without engineering the mastering stage.
