What the Broadcast Preset Does
Six processing stages specifically tuned for spoken-word content — not music. Each stage addresses a specific problem that podcast recordings have.
High-Pass Filter
Removes rumble below 80 Hz — keyboard vibrations, AC hum, room noise
De-Esser
Tames harsh S, T, and P sounds that digital mics over-emphasise
Presence Boost
+2 dB at 3 kHz — makes voices sit forward and cut through earbuds
Bus Compression
Fast attack/release for consistent dynamics between multiple speakers
Loudness Normalisation
Targets −16 LUFS integrated — Apple Podcasts, Spotify, every major host
True Peak Limiter
−1 dBTP ceiling — prevents digital clipping on all streaming decoders
Podcast Loudness Standards by Platform
Every podcast platform normalises audio. If you're too quiet, they turn you up (adds noise). If you're too loud, they turn you down (kills punch). MixMasterAI targets −16 LUFS — compatible with every major platform.
How to Master Your Podcast Episode — 4 Steps
Export your episode as WAV
From Audacity, GarageBand, Adobe Audition, Reaper, or any DAW. WAV gives the mastering chain the most headroom to work with.
Upload to MixMasterAI
Go to the homepage and drag your WAV onto the upload circle, or click to browse. Files up to 200 MB are supported.
Select the Broadcast character
In the character grid below the upload, click Broadcast. This applies the podcast-specific processing chain instead of the music-focused presets.
Download and publish
Processing takes 60–90 seconds. Download as WAV (lossless, best for archiving) or MP3 (smaller, fine for direct upload to podcast hosts).
Podcast Mastering — Common Questions
What LUFS should a podcast be mastered to?
The industry standard for podcasts is -16 LUFS integrated (same as Apple Music). Spotify Podcasts normalises to -14 LUFS. Most podcast hosting platforms (Buzzsprout, Libsyn, Anchor) recommend between -16 and -19 LUFS. MixMasterAI's Broadcast preset targets -16 LUFS, which is compatible with every major platform.
What does podcast mastering do?
Podcast mastering applies: (1) a high-pass filter to remove low-end rumble below 80 Hz, (2) de-essing to tame harsh S and T sounds, (3) presence boost around 3 kHz to make vocals sit forward, (4) bus compression for consistent dynamics between speakers, and (5) loudness normalisation to -16 LUFS so your podcast plays at the right level on every platform.
Is MixMasterAI's podcast mastering really free?
Yes. MixMasterAI is completely free — no account, no credit card, no watermark, no monthly subscription. Upload your podcast episode, select the Broadcast character preset, and download your mastered WAV or MP3.
How long does podcast mastering take?
Most podcast episodes (20-60 minutes) master in under 90 seconds. The tool runs entirely in your browser using the Web Audio API — there is no upload to a server, so processing speed depends only on your device.
