CALCULATE / 120BPS / MODULE
AUDIO BITRATE
Estimate audio file size from playback duration and target bitrate.
ESTIMATED SIZE—MB
BINARY SIZE—MiB
DATA / HOUR—MB
Calculated from bitrate × duration. Real files may differ slightly because of container, tags and codec overhead.

COMMON QUESTIONS
How is estimated audio file size calculated?
The selected bitrate is multiplied by duration, then converted from bits to bytes. Container metadata and codec overhead can make a real file slightly different.
What bitrate should I choose for audio?
It depends on codec, source material and quality goals. This calculator intentionally estimates size rather than prescribing one universal bitrate.
