Audio Storage Math

Audio Storage Math is a calculator for uncompressed integer PCM audio payload size. Enter sample rate, bit depth, channel count and duration in whole seconds. Start with labeled stereo examples and adjust the inputs. See exact bytes, sample frames and bits, with a breakdown of the calculation and any final partial-byte rounding. Switch between kB and KiB, MB and MiB, or GB and GiB. Decimal and binary values appear together with their unit bases. Headers, metadata, compression and padding are excluded. Compare two formats at the same duration to see which needs more space and the exact byte difference. Reuse saved inputs on either side or load a complete comparison. Calculations work offline. Drafts and unit choices last for the session; only inputs you explicitly save are stored locally. View, edit or delete named formats and comparisons in Audio Storage Math.
