Listeners notice level jumps before they notice codec settings. FFmix’s podcast preset applies ffmpeg’s loudnorm filter with a −16 LUFS integrated target, −1.5 dB true-peak ceiling and controlled loudness range, then exports a practical 192 kbps MP3.
Treat this as a delivery step, not a mix repair button. Normalize after editing voices, music and noise; then listen to the output once before publishing. The source stays unchanged and the episode never leaves your Mac.
Steps
- 1 Drop the finished episode audio or video into FFmix.
- 2 Choose the Podcast loudness −16 LUFS preset.
- 3 Review the −16 LUFS integrated target, −1.5 dB true peak and MP3 output.
- 4 Confirm, then spot-check the normalized MP3 before publishing.
Advanced: canonical ffmpeg recipe
This is the canonical recipe. FFmix adapts encoder flags to the engine on your Mac, then shows the final command; the command shown is the command run.
ffmpeg -i "episode.wav" -vn -af loudnorm=I=-16:TP=-1.5:LRA=11 -c:a libmp3lame -b:a 192k "episode-normalized.mp3"Drop a file and go — all local, nothing uploaded.
FAQ
Is −16 LUFS right for every podcast?
It is a common stereo podcast target. Mono programs are often delivered closer to −19 LUFS, so follow your host's specification when it differs.
Does loudness normalization fix background noise or bad mic balance?
No. It controls overall loudness and peaks; it does not replace editing, noise reduction, EQ or mixing between speakers.
Can FFmix pull the audio from a video episode first?
Yes. The preset ignores the video stream, applies loudnorm to the audio and exports a 192 kbps MP3 in one local command.
