WAV File sizes chart
« on: April 26, 2010, 06:13:39 PM »
I made a chart today (file location attached) that tells how much 16 and 24 bit 44.1 kHz WAV audio can fit on a 4 GB and 16 GB memory card. I've joined the all-in-one multi-track recorder team and wanted to know at a glance what those numbers were. These numbers are only approximations. I don't know how to account for the fact that (1) 16 GB card really stores less then 16 GB of data though...

I searched everywhere for this information and couldn't find it. If someone knows of a more accurate source for this info, please let me know.

Edirol usually has a chart of sorts on their site.  There is one for the R-44 on an 8GB card.  Click on the Specifications tab at the following link.

If you have a problem relating to the Live Music Archive (http://www.archive.org/details/etree) please send an e-mail to us admins at LMA(AT)archive(DOT)org or post in the LMA thread here and we'll get on it.

The Sound Devices audio calculator is a pretty neat tool, although not a chart.  Simply enter the storage size, bit depth, and sample rate.

the confusion of why a 16 GB card is not truly 16 GB is because of how the term gigabyte is defined and calculated.
http://en.wikipedia.org/wiki/Gigabyte

if you look at the chart on the right, you will notice the Binary & Decimal have two different values.

Advice is a form of nostalgia, dispensing it is a way of fishing the past from the disposal, wiping it off, painting over the ugly parts and recycling it for more than it’s worth.

I put together the attached chart (see PDF below) a while back.  It gives a good range of scenarios... 16 bit vs 24 bit... 44.1, 48, 88.2, 96, 176.4, or 192 kHz....  2 channels or 4 channels, etc, etc....

If you're cutting it so close that you need a chart, perhaps you should just stick to the lower sampling rates.  Or get a second or bigger card.  Throw in voice activation recording modes and any charts go out the window. 

A CD is 16/44.1 for 2 channels at a cost of 700MB per 74 minutes.  Over simplified to 1GB an hour.  If you're going to be recording 16 hours of content in a single sitting, you've got greater needs than a chart.  Anyway simple math can be applied to the CD quality specs to derive most approximate file size to time ratios.  24 bit would be 150% of 16 bit, or 1050MB per 74 minutes.  Still basically 1GB an hour.  5.6 DSD for 2 channels rounds up to about 6GB an hour, a little closer to 5, but always nice to play it safe.

Unless you have some variable track count that you need to account for, I'm not sure why you'd need a chart.  At any rate, any decent recorder should give you time/capacity left as well as battery life remaining.  It might not be easy to find or accessible while recording, but a feature on many stand alone devices.
