✳ FREE CALCULATOR
Audio bitrate calculator
Estimate how much space an audio track takes at a given bitrate, and what that costs inside a video file.
- Audio file size
- 4.1 MB
- Per minute
- 1.4 MB
- Uncompressed equivalent (CD WAV)
- 30.3 MB
- Compression versus that WAV
- 7.3× smaller
16-bit 44.1 kHz stereo, for comparison.
Calculated as: size = kbps × 1000 × seconds ÷ 8
What this assumes
- Assumes constant bitrate; VBR encoders vary around the target.
- Speech stays clean at far lower bitrates than music does.
Koldflux works these numbers out for you when it exports - the calculators exist because our own pipeline needed them first.
