Audio Cleanup for Podcasters

Your podcast episodes have inconsistent audio quality — remote guests with noisy environments, host recordings with room echo, or background noise that distracts from the conversation.

Podcast audio quality has a direct relationship with listener retention and subscriber growth. Industry benchmarks show that listeners tolerate average content with great audio far better than great content with poor audio. For podcasters, audio cleanup is part of every episode workflow. **Remote interview cleanup — the biggest challenge:** Remote guests record in different environments with different equipment. Their audio arrives via Zoom, Riverside, Zencastr, or similar — already processed by that platform's codec. Common guest audio problems: home HVAC noise, room echo, bandwidth-compressed artifacts, consistent hiss from budget interface preamps. Best practice: ask guests to use Riverside or Zencastr's local recording feature, which captures uncompressed audio directly to their device rather than compressing it through the call. This gives you the best starting material to process. **Per-episode processing workflow:** 1. **Noise removal** (AI): Upload each track separately. Host and each guest processed independently — different environments need different settings. 2. **De-essing**: Podcast mics placed close to the mouth emphasize sibilance ('s' and 'sh' sounds). A de-esser (Fabfilter Pro-DS, or built-in de-essers in most DAWs) targets 6-9kHz to reduce harshness without dulling the voice. 3. **Compression**: 3:1 to 4:1 ratio, -20dBFS threshold, 10ms attack, 100ms release. Reduces dynamic range so quiet and loud moments are both audible. 4. **EQ**: High-pass at 80Hz (removes handling noise and low-frequency room rumble). Boost 2-4kHz lightly for presence (+1-2dB). Cut 300-400Hz if the voice sounds boxy. 5. **Normalization**: -16 LUFS integrated for podcast platforms (Spotify, Apple Podcasts). Use a loudness meter (Youlean Loudness Meter is free) to verify. 6. **Export**: MP3 at 128kbps mono for voice-only podcasts, 192kbps stereo for music-heavy shows.

What You Get:
