Is this calculation right?
I hope I didn't fucked up with switching bits and bytes
Thanks for the help,
Willem
Bitrate 64 kbps
Playtime 5 min
64 kbps = 64000 bps
5 min = 5 x 60 = 300 sec
64000
64000 bps = ----- bytes/sec
8
64000 * 300 2400000
----------- = 2400000 bytes = ----------- = 2.29 MB
8 1024 * 1024

Wow that's really neat but does not go up to 320kbps.

It's correct.
Normally and usually a kilobit = 1,000 bits (e.g. when data transfers speeds are showed), but a kilobyte = 1,024 bytes (e.g. when file sizes are showed).
Only HD manufacturers have a bit different math. They think that 1 GB = 1,000,000,000 bytes and so on. I guess a bigger GB amount looks better.
Thanks for that tool
This calculation is right for Bytes.
Mabe the tool is wrong regarding Bytes to KBytes, MBytes, etc...
It uses a factor 1000 I thought for storage they used a factor 1024,
exept for Hard Disk's because it looks better that way

Hello Alex B,
I think we typed it the same time

Yeah, and that tool indeed shows incorrect KB, MB and GB values.
Also, the real 128 kbps 2min 30s files I have are almost exactly 2.3 MB. (I don't have 64 kbps files.)
Very interesting. Thanks for this. I have a lot of 64kbps files (LAME -V9 -vbr-new), and I've been wondering about how to calculate filesizes as well. According to your formula, a -V9 encoded file (~64kbps) would take up 0.46MB per 1 minute of music, so an hour's worth would be 27.47MB. I'm trying to find out the maximum number of songs I can fit in a 1GB flash player with V9, V8 and V7.
