NOTE: I assumed that at sampling rates above 48k you would not use a bit depth of 16. If anyone wants the data for 32-bit samples, post a comment and I can add the data.
As an example of using this chart, if recording at 192/24, 20 tracks of audio would use 659.18MB of disk space per minute. So a 5 minute song using 20 tracks at 192/24 would take 659.18 x 5 = 3,295MB = about 3.3GB of disk space!
I use this for live recordings at 44.1/24 to determine what size SDHC card I need for my Capture session. Recording 16 tracks at 44.1/24 requires about 120MB per minute of recording. Most of the gigs I record are 4 hours, so that means I need a 32GB card to fit the 29,068MB of data.
