Bytes ≈ sampleRate × (bitDepth/8) × channels × seconds. No headers.
Bytes ≈ sample_rate × (bits/8) × channels × seconds with positive rate, seconds, integer channels 1–32, and bit depth 8/16/24/32. This ignores headers (WAV/AIFF containers) and compression; MiB uses 1024².
This calculator uses plain decimal numbers. If a result looks wrong, check whether you used a comma instead of a dot (or vice versa) where the field expects one.
