AudioSize
Calculate storage

PCM frames · bytes · recording time

Know how much uncompressed audio really fits.

AudioSize converts recording settings into complete PCM frames and exact payload bytes, or reverses a stated capacity without crossing it.

Open PCM calculator

No account, audio upload, backend, codec guess, or result URL.

Three explicit format choices

Set the frame, then size duration or storage

01

Set sample rate and stored bits

Reviewed presets fill values but never recommend quality.

02

Count stored channels

Every channel contributes one stored sample to each frame.

03

Choose duration or capacity

Upward frame fit covers time; downward fit respects capacity.

Focused storage arithmetic

Useful before a take, export, archive, or storage purchase

  • Field recorder and SD-card planning.
  • Studio multichannel PCM estimates.
  • Digitization and archival payloads.
  • WAV export upper references before metadata.

Worked storage

Executable examples use the same complete-frame arithmetic as the calculator.

Plan an uncompressed PCM recording without guessing

Choose duration or storage, set the recording format, and copy a result that never exceeds its stated arithmetic boundary.
