Hey guys,
I was wondering if there's any way to check, if a 320kbps mp3-file is really 320kpbs.

I got a sample CD, and some sounds... hm.. I don't know... just don't sound like 320kpbs.


Let me know ok?

right click on one of the sample files and goto properties.

umm.. just left click on a file and it will tell you whether it is 320 kbs or not... at least in windows...

320 kbs doesn't mean something will sound good. It just means more points are used to interpolate a sound file than 192 kbs.

Most people can't tell the difference above 192 kbs anyways, even if you have hi-fi

no, the question is, how do I know if a 320MP3 isn't just encoded from a 128kbps "up" to 320kpbs

You don't. Unless you have the original source to compare with.

you could try to take a look to see if it contains any information above 16000 khz using a spectral analyzer....

But you can't really "tell" unless you have the sample it is "supposed" to sound like.

If the sample is crap to begin with, it will sound like crap no matter how you encode it.

I see. Somehow I thought that it's possible "seeing" if it's a re-encode using spectral tools

No.. for example

if this is 128 kbs

2-2-0-0-2-2-2-0-

when you re-encode it to 320 kbs it will add extra information making it something like:

2221000122222100

the only thing you can tell is that there 16 digits of information versus the 8 digits of information. The extra 1's added in there are to estimate what the value would be in between the 2's and 0's

You can however tell if something sounds like crap or not, because ultimately your ears judge what something sounds good, not the encoding

I suppose there may be tools out there to detect such things, but then that's not in the scope of what I undersatnd

thanks JL for the detailed answer!

i thought computers only worked 1s and 0s (on/off)?

well yes... but then again the example wasn't meant to be binary... just to show what it means when a lower quality means that there will be an interpolation between 2 points

oh. hexa?
