✳ FREE CALCULATOR
Uncompressed audio size calculator
Work out the size of uncompressed PCM audio from its sample rate, bit depth and channel count - the reason a WAV dwarfs the MP3 of the same recording.
- Uncompressed size
- 30.3 MB
- Data rate
- 1411 kbps
- Per minute
- 10.1 MB
- Versus a 128 kbps MP3
- 11.0× larger
Which is the entire reason lossy audio formats exist.
Calculated as: bytes = sample rate × bit depth ÷ 8 × channels × seconds
What this assumes
- Applies to uncompressed PCM (WAV/AIFF). FLAC is lossless but compressed, so it lands roughly half this.
- Ignores the small header.
Koldflux works these numbers out for you when it exports - the calculators exist because our own pipeline needed them first.
