Understand the sound. Make a better recording.
Practical audio articles with worked examples, primary sources and free tools you can use on your own file.
The podcast audio workflow
Recording, editing, repair, loudness and delivery. Follow the whole process, then use the articles below for the decisions that need a closer look.
LUFS vs dBFS vs dBTP: What Your Audio Meter Means
Understand loudness, sample peaks and true peaks with a reproducible tone example. Learn why a file can peak near zero and still sound quiet.
