The challenge
What makes Podcast different to master
Voice intelligibility across earbuds and speakers
Podcast listeners use everything from airpods to car stereos. The voice must be clear and intelligible on every playback device. Mid-range clarity, controlled low-mids, and de-essing are the core requirements.
Tight dynamic control without robotic compression
Conversation varies in volume. A gentle compressor evening out loud and quiet moments keeps the podcast comfortable to listen to without creating the squashed, over-compressed sound that sounds unnatural for speech.
Broadcast loudness standard at -16 LUFS
Apple Podcasts, Spotify, and most broadcast standards target -16 LUFS. This is quieter than music streaming targets and appropriate for spoken word, which benefits from more dynamic range than music.

How MixMasterAI handles Podcast
De-esser removes sibilance from voice recordings
MixMasterAI applies a broad-band de-esser targeting 5-8 kHz to remove sibilance and plosive harshness from voice recordings. The de-essing is gentle enough to preserve natural speech character while eliminating listening fatigue.
Presence boost improves intelligibility
A 2-4 kHz presence boost lifts vocal clarity and improves intelligibility on small speakers. This is the most important frequency range for speech comprehension and is the defining element of broadcast voice processing.
Broadcast normalization at -16 LUFS
MixMasterAI normalizes every podcast master to -16 LUFS integrated, matching Apple Podcasts, Spotify Podcasts, and international broadcast standards. True peak protection at -1 dBTP is applied before delivery.
Recommended settings
Use Podcast genre and Broadcast character for the best results on Podcast tracks.
These settings are pre-selected when you visit MixMasterAI, or you can choose them manually in the genre and character pickers.

Questions about mastering Podcast
Can I master podcast audio free online?
Yes. MixMasterAI is free, no account, no watermark. Upload your podcast export, select the Broadcast character, and download a broadcast-spec WAV and MP3 in under 60 seconds.
What LUFS should a podcast be mastered to?
Apple Podcasts and Spotify Podcasts both target -16 LUFS integrated. Mastering to -16 LUFS ensures your podcast plays at the right volume relative to other shows. Louder targets like -14 LUFS are for music, not speech.
Does MixMasterAI remove background noise from podcasts?
MixMasterAI is a mastering tool, not a noise removal tool. It processes dynamic range and EQ but does not perform spectral noise reduction. For background noise, use a dedicated tool like Adobe Podcast Enhance before uploading.
Can I master a podcast with multiple speakers?
Yes. MixMasterAI processes the finished stereo mix, so a podcast with two or three speakers mixed into a single stereo file is handled the same way as a solo episode. Make sure your mix is balanced before uploading.
