OK peeps, something is niggling at the back of my mind so I thought I would seek a wealth of information from all and sundry to see if anyone can help me out. The question is:- As there are many discussions around the site about bitrates and what is considered as acceptable and unacceptable bitrates, is there a tool/programme that can trawl through an MP3 collection and have variable search paramaters so it could flag up say any files that are under 192kbps or any other bitrate you may wish to find?

In iTunes, I can display bitrate, and easily make a playlist, say "bitrate < 192kbps" and flag it in any number of ways.

Hi ashsarhaz93


If these MP3-files are stored on your hard drive, you can let Tag&Rename find all of them and sort them in ascending or descending order according to file size

Hi ashsarhaz93,

I covered this topic last month at:

http://www.aom3.org/forum/f2/hearing...20-a-2240.html (Hearing the difference between 192 & 320)

Now you should read the whole thread and then move on to:

http://www.aom3.org/forum/f5/cripple...ct-2268-2.html ("Crippled"? Really, RIAA? Is that a fact?) and follow it through to the end.

Now regarding the explanation of mp3 bit rates the following is a rough guide:

384k bps = real cd quality

320 kbps = near cd quality (but most sites say this is cd quality)

192 kbps = high quality bit rate (often commercially referred to as near cd quality)

Most encoders will only encode mp3s up to 320 kbps which is damn close to cd quality. As many mp3 players will top out at this bit rate then the higher rate is academic anyway. The sound quality at this level is indiscernible from the real cd quality.

I guess the only way to explain the difference between 320 kbps and the original cd is that the former is a little bit more metallic of harsher than the original cd but it's so marginal that only audiophiles would quibble over the difference.

Now as you read the explanations I gave in the second link the source material has a bearing on the quality of the output. For example, the bit rates offered by the iTunes Store are superior to the equivalent bit rates offered by all the outlets advertised on aom3. And before anyone starts disagreeing with me please check out the second link. Then you can disagree all you like. Hell, this is a pretty open site anyway

Being subjective, many people are happy with bit rates at 192 kbps whilst I prefer rates as high as possible. In a nutshell your individual tastes will have a bearing on your choice of the bit rate. I didn't mention rates as low as 128 kbps because at that level the music sounds like it was recorded in a dark dank tunnel frequented by rats and cockroaches and the like. But again the source material has a bearing on the sound quality. And individual tastes also have a bearing.

Variable bit rates are another source of confusion but unless anyone wants an explanation on that one I'll let it pass it through to the keeper (cricket analogy you heathens).

Now if you want any further information then a good link then the following is a good site but it is a bit technical. The link is:

See ya!

Where I refer to 384 bps it should read 384 kbps.

>> an MP3 collection and have variable search paramaters so it could
>> flag up say any files that are under 192kbps or any other bitrate

excellent tools for yr mp3 collection, doing this and much more, and are all free:

- MP3VAL - checking for broken and incorrect compression, missing headers,
incorrect lenght, can also fix many things

- EncSpot - checks for bit rates, gives graphic display, also checks for broken
files (see if you can find the also-free PRO version)

- MP3tag - the ultimative! hard to explain what it does NOT do!

anybody interested, try these out and let us know what you think.

greets - henry
