i can still hear distortion in songs that are ripped in 320. just a thought.
not a very profound one...
I never understand what people mean when they say they hear "distortion"...I never notice it?? Maybe it's because I don't really pay attention to it...or it could just be because I have shitty speakers (creative inspire 5200's)
i'd say. :)Quote:

Theres something wrong if your hearing distortion, you shouldn't be hearing distortion in mp3 files, unless there encoded wrong, or something in your setup is messed up, eq settings etc.Quote:

no, it's just loss in the quality of the file.Quote:

How can a digital file loose quality?Quote:

It's not a tape...
There is no way that there oould be distortion, unless the source has distortion, or something is wrong with the way you encoded it. Or the media player your using has something messed up, like an eq setting, etc.
Unless you have really good ears, a 192Kbps MP3 will not sound any different than the CD.
Apparently someone was sleeping in class on the day that they went over the difference between a lossy and a lossless compression format.Quote:

Lossy formats (MP3) will "lose" data that is not stored in the sample. Depending on your sample size in comparison to the actual data stream dictates your loss.
Lossless formats (zip) don't "lose" data, they usually replace repeating fields of data with a token, then create a table so that when uncompressed the tokens can be replaced with the appropriate data.
Proof: Take any sound file that is in its origianl wave format and encode it to 320bps MP3...if the MP3 is smaller (which it most likely will be) then audio data was lost.
Idiot356, digital or not you are taking a .wav file of a song (upwards of 150mb each) and compressing it down to a 6-15mb file. If your expecting there will be 0 loss in quality just because it's "digital" you be wrong~
pwned.
if your hearing distortion, either your source material is distorted, something went wrong during encoding, OR you are getting clipping. try using MP3gain on that file, might clean it up.
"I can still hear distortion in songs that are ripped in 320. just a thought."
Sorry PinchyCM but something is wrong there. There is no reason for you to hear distortion at even 160 if its properly encoded. Please do give the tracks you are hearing the distortion on because it might be that you have your treble set to 75+? on your audigy? Or was that 007 from the klipsch forums? Anyway something is wrong with that because you should not get any distortion.
"Unless you have really good ears, a 192Kbps MP3 will not sound any different than the CD."
I would have to completely agree with you here. Only on certain classical and very detailed jazz peices can you actually make out the difference, and its very very slight between 192 and 320.
I would try re-ripping it, and maybe change some settings pinchy, no reason at all why you should be hearing distortion , its likely:
1.encoding of the mp3 file
2.the song itself was badly recorded aka stupid sound engineers(i have owned a few cds that had distortion straight out of the jewlcase.)
3.Soundcard settings aka treble - bass EQ - EAX - CMSS etc.. should all be at 0.
4.Speakers, the speakers themselves are makeing it sound distorted
Yes I realize it's a lossy format, yes you loose data.Quote:

But that does not change the fact that an MP3 encoded with a qaulity encoder 192 and above, will more than likely not be distinguishable against a cd. It also depends on what kind of music it is.
But I remember hearing that Dolby Labrotories did a test in there refrence room, they encoded an MP3 I think at 160, and played the same song from the cd, switched back and forth, and could not tell the difference. Now, I don't know if this was true or not, but do me a favor, take your highest quality MP3 and switch back and fourth between the CD with that song, if you can tell a difference, you didn't encode it very well, or you have k9 ears.
And when I said a digital file shouldn't be loosing quality, I thought he meant his MP3 files were gradually loosing quality, of course the wav file and the original file will loose data, but quality if encoded right should not be lost.
Anyone ever heard of the placebo effect (sp??) Someone blind fold the buy. Play the same song, 5 from the CD and 5 from the 320 quality MP3 and lets see for real how many times he can diferentiatethe 'distortion' You'll notice him point out the CD to have distortion once in a while too : )
Psst, that someone can't be you pinchy : ) The test has to be given very carefully, such as attempting to have both output devices already playing (because you can hear an ever slight sound from a CD going into its spin).
i ripped a copy of that song off my CDs this time, and i still think i can tell at specific points, maybe the placebo effect :). i asked my roommate, and he says he can tell a difference, and i didn't tell him which was which. i used a frew tracks off the evanescence cd btw, a great selection to show off the range in the klipschs. but whoever says they can't hear the diff between 160 between 320 is deaf. if you know anything about sampling, even if encoded right, you lose quality. i mean, you take a continious signal x(t), you take points from it discretly -> x(k),from a fixed interval T, and you lose parts of it. oh, and i have fantastic hearing. :)
