Bitrate[edit]

${\displaystyle bitrate={\frac {size}{time}}}$

${\displaystyle size=bitrate\times time}$

${\displaystyle time={\frac {size}{bitrate}}}$

Bitrate is filesize divided by playtime, and playtime is filesize divided by bitrate. Calculations for digital audio players' length were done like this:

10 GB == 1024 x 1024 x 1024 x 8 bits
      == 8589934592 bits

8589934592 /  64000 == 134217.728  seconds → 37 hours 16 minutes
8589934592 / 128000 ==  67108.864  seconds → 18 hours 38 minutes
8589934592 / 320000 ==  26843.5456 seconds →  7 hours 27 minutes

Audio bitrates usually done with 1k == 1000. --Kjoonlee 08:33, 8 July 2007 (UTC)[reply]

10GiB actually equals 85899345920 bits (10 x 1024 x 1024 x 1024 x 8 bits). 4.242.147.41 (talk) 19:05, 20 March 2008 (UTC)[reply]

Oops. :) New numbers updated using the "GNU units" program. 372.82, 186.41, 74.56 hours. --Kjoonlee 06:53, 14 April 2008 (UTC)[reply]

Are digital media players usually measured in GB or GiB? I was under the impression that they were in 1000 GBs. We might want to fix the article to confirm this. 4.242.147.156 (talk) 23:46, 24 December 2008 (UTC)[reply]

Did you know that with no proper ==headers==, the table of contents comes out at the bottom of the article.Jidanni (talk) 01:07, 14 June 2008 (UTC)[reply]

Five years later, the table of contents has moved to the top. At this rate, the TOC will not reach the moon. OSborn ^arf_contribs. 03:15, 20 August 2013 (UTC)[reply]

Improvement suggestions:
An excellent addition to this table would be adding the year that each technology was introduced.

Also for completeness, a row can be added to list a high capacity hard drive. Current portable versions are as high as 2TB, with nonportable at 4TB. As the list stands right now, there is nothing shown in the terrabyte capacity range.Vybr8 (talk) 02:09, 30 September 2013 (UTC)[reply]

There are many other recording media, such as film, paper, magnetic tape, and so on. Graefestrasse (talk) 09:54, 9 May 2023 (UTC)[reply]
