Calculateur de Audio File Size
Estimate audio file size from bitrate and duration.
Formula and method
This calculator computes Estimated size directly in your browser without sending data to an external server.
Mathematical formula
- Estimated size:
bitrate × minutes × 60 ÷ 8 ÷ 1000
Variables and parameters
- Audio bitrate (bitrate): default value 320 kbps.
- Duration (minutes): default value 10 minutes.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
