Let's say you have an MP3 that is exactly 650 MB that plays at 128 Kbps. How long would that MP3 play for?

650mb is 650,000 kb.

if you read 128 kb per second, then 650,000 / 128 = 5,078 seconds.

that is 84.6 minutes. so 1 hour and 24 minutes, approximately - unless i made a math mistake.

oooops 650MB = 5200mb = 5200,000kb/128kbps = 40625seconds/60= 677minutes / 60 = 11hrs????

Why don't you just make ten louder and make ten be the top number and make that a little louder?

Aren't MP3's compressed ?

If anyone has ever converted a WAV file to MP3, you'll see the files squeeze to about 1/10th the size.... In the early days of CD burning, you had to convert MP3 files to WAV before you could burn them and I remember the WAV files were almost always 10X bigger....

So essentially, a 40 Megabyte WAV file and a 4 Megabyte MP3 will play for exactly the same time even if they are the same bitrate.

It makes it hard to calculate
