Is this the complete file or disk size?
Mistake: Treating a result as valid outside the described scope.
Fix: No. Headers, metadata, filesystem overhead and compression are excluded; GB uses 1000³ and GiB uses 1024³.

About this tool
Use tool ↑Budget uncompressed audio payload for recording and archive sessions.
Frames round up from duration × sample rate. Bytes = frames × channels × stored bits/8 × copies. Use container bits, not valid precision (20-bit audio in a 24-bit container uses 24).

Common mistakes and quick fixes
Limits and key assumptions
- No. Headers, metadata, filesystem overhead and compression are excluded; GB uses 1000³ and GiB uses 1024³.
- Use container bits, not valid precision (20-bit audio in a 24-bit container uses 24).
- Displayed results may be rounded; rounding does not add measurement precision.
