i have ripped a cd using CDEX encoded at 160 kbps & extracted to a compressed audio file. the file size is about 31mb for a cd with a playing time of about 28 minutes. does this sound about right?
not used to ripping cd's to mp3 really, noticed file sizes are much bigger on cdex menu's when extracting.
thanks
If you are using 160kbps CBR mp3s, then that size is about right. Using CBR you can easily calculate how big the resulting file will be (Length in seconds x Bit rate / 8 = size in kilobytes). If you are using a VBR setting, then it's harder to guess, as the bit rate changes throughout the track. Resulting sizes can be much larger or smaller than expected.
I think the cdex sizes you see are the uncompressed wav files size ie size before mp3 encoding.
If you have the HD space, you might want to try ripping/encoding at 192kbps or higher, as most people consider this the minimum for 'cd-quality'. ymmv though.

1Meg->1Min looks right. Actually the formula is File Size = bitrate * time, so ((160 * 28 * 60) / 1 024) / 8 = 32.8125MB
