Broadcast WAV File Size Calculator
Exact uncompressed file size for any WAV/BWF deliverable from sample rate, bit depth, channel count and duration — plus the data rate.
The broadcast staple — 48 kHz / 24-bit stereo — runs ≈ 16.5 MB per minute. A 90-minute 5.1 printmaster at the same resolution is ≈ 4.5 GB, which is why mezzanine specs care about this arithmetic. BWF metadata chunks add only kilobytes.
