How the calculation works
Bitrate = sample rate × bit depth × channels
File size = bitrate × duration ÷ 8

PCM versus compressed audio
WAV/PCM storage is determined directly by sample rate, bit depth, channels and duration. MP3, AAC, Opus and similar compressed formats instead use an encoded bitrate, so their storage is better estimated with the Streaming Data & Storage calculator.
