File sizes in different audio formats

A one minute audio track recorded in the different audio formats yields files of these approximate file sizes:

File size for 1 minute of audio, in MB
Sample rate
(kHz)
16 bit 24 bit
mono stereo mono stereo
44.1 5.1 10.2 7.6 15.2
48 5.5 11.0 8.3 16.6
88.2 10.2 20.4 15.2 30.4
96 11.0 22.0 16.6 33.3
176.4 20.4 40.8 30.4 60.8
192 22.0 44.0 33.2 66.6

When recording more than two channels, multiply the number of channels by the mono file size for the sample rate & bit depth you are using. For example, if you are recording in 5.1 (6 channels) at 24 bit / 96 kHz (16.6 MB per minute), you will use 99.6 MB per minute.
