mb to time

[falcon1933]

i have 8 mp-3 disc that has 299.3,195.1,69.1,159.1,190,198.3,165 and 125.8 mb, playing time, how is that converted to real time ?? again how is mp-3 mb converted to real time.

thru trial and err the closest aprox. time i can come up w/is, for every 50mb = 1 hr. playing time for mp-3 playback, any feedback on that :?:

This site explains it fairly well: http://iaudiophile.net/forums/archive/index.php/t-2081.html

sorry about that, maybe instead of real time i should have said playback time, would that be correct, anyhow that is what i'm looking for.

I'm not an audiophobe but I know a little about math. The website http://iaudiophile.net/forums/archive/index.php/t-2081.html is relevant. If you know the bitrate (kbps) of the recording(s), you can calculate the MB per minute using the formula provided. (Finding the bitrate of the recording may be another story!)

The total recording in MB’s / MB/min will give you the playback time.

Borrowing the formula from the website, if the bitrate of the recording was 320 kbps, 320*15/2048 = 2.34375 megabytes per minute, so:
299.3 MB recording / 2.34375 MB/min= 127.70 minutes playback time,
195.1 MB recording / 2.34375 MB/min = 83.25 minutes playback time,
and so on.

Is that what you're looking for?

WOW !! that is very heavy, yes that is just what i'm looking for, now all i have to do is decipher all this good info.and put into some practical application, i had too many people telling me that it could not be done, hey thanks a bunch.
