Audio File Size
Estimate encoded audio size from total stream bitrate.
Your numbers
Encoded size
Bitrate is the whole encoded stream; do not multiply it by channel count. Tags and container overhead are excluded.
Scenario comparison
Up to three snapshots in this tab. Loading one replaces the current inputs.
Formula
Use S = bt/8000. b is the audio bitrate in kbps, t is duration in seconds, and S is decimal MB.
Estimate encoded audio size from total stream bitrate.
Worked example
- Total encoded bitrate (kbps)
- 320
- Duration (minutes)
- 5
- Encoded size
- 12 MB
Scope and limitations
Bitrate is the whole encoded stream; do not multiply it by channel count. Tags and container overhead are excluded.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
