Questions
Which loudness should I choose?
−16 LUFS for podcasts (Apple and Spotify both recommend about this), −14 for music and video on streaming sites, and −23 for European broadcast. Use −19 for podcasts in mono.
What is LUFS?
Loudness Units relative to Full Scale: a measure of how loud audio sounds to people, not just how high its peaks go. It follows the ITU-R BS.1770 and EBU R128 standards used by broadcasters and streaming services.
What does the peak ceiling do?
Raising the loudness can push peaks past the maximum and cause distortion. A limiter gently turns the loudest moments down so they stay below the ceiling. −1 dBFS leaves room for later conversion to MP3 or AAC.
Why WAV?
So the audio isn’t compressed twice. Convert it to MP3 or AAC afterwards if you need a smaller file.
