AudioSize
Calculate

PCM payload · storage planning

Calculate exact PCM bytes or recording time.

AudioSize fits whole sample frames and keeps decimal GB separate from binary GiB without uploading audio.

The exact result is PCM sample payload only. WAV/BWF/AIFF headers, metadata, filesystem space, recorder reserves, and compressed formats are excluded.

345600000 frames × 6 B = 2073600000 B

Frame counts and bytes remain exact integers. The ≈ sign appears only when a rational duration or unit conversion has a non-terminating decimal display.
