About the Audio calculator
Work out the uncompressed file size of digital audio from the sampling rate, bit depth, number of channels and duration.
How to use the Audio calculator
- Choose the Sampling Rate and Bit Depth.
- Choose the number of Channels (mono or stereo) and enter the Duration (Minutes).
- Press Calculate.
Formula and method
Size (bytes) = Sampling rate × Bit depth ÷ 8 × Channels × Seconds
Worked example
3 minutes of CD-quality stereo (44.1 kHz, 16-bit, 2 channels) is 44,100 × 2 × 2 × 180 = 31.75 MB uncompressed.
Tips
- Formats such as MP3 and AAC compress audio to a fraction of this size.
- Higher sampling rates and bit depths give larger files with diminishing audible benefit.
