About the Audio File Size Calculator
Estimate uncompressed PCM or compressed audio size from duration and encoding settings. It helps translate production specifications into practical dimensions, durations, or file-size estimates.
The calculation uses encoding, duration hours, duration minutes, duration seconds, pcm sample rate, pcm bit depth, channels, and compressed bitrate.
How to use it
- Review the starting values for encoding, duration hours, duration minutes and replace them with your own.
- Choose any available units or assumptions, then select “Calculate audio size.”
- Read the labeled result, compare another scenario if needed, and copy the output for your notes.
