Acutally CoolEdit can, but it tells you absolutely nothing about how your brain interprets what your ears are hearing.
Of course they represent real "distortions"
"(The mere fact that Joint Stereo is used in lossless compression ought to be enough to destroy - in one stroke - the myth that JS "destroys stereo separation")" (cite from http://harmsy.freeuk.com/mostync/) - I like this argument! It's quite cogent But then I don't understand for what reason most CBR mp3s are made using S mode (even on LAME).
And for what reason all other Stereo modes are supported by LAME?
QuoteAcutally CoolEdit can, but it tells you absolutely nothing about how your brain interprets what your ears are hearing.CoolEdit can subtact noise, but it's not the same. It uses the noise sample not "as is", but as a kind of "spectre", am I wrong? Or did I miss some function of CoolEdit, or Adobe Audition (for now)?

QuoteOf course they represent real "distortions"But LAME 3.93 and GoGo didn't produce them... Is this "feature" (new to 3.95 and the following versions) just an improvement - i.e. to give more bits to the "more useful" freqs?
...So, as I understood, the only way for me to get a better quality is to get a better soundsystem and to carry out the ABX test.
By the way, can you suggest how to choose most appropiate sample for tests? I like metal music, and oftenly there are lot of live cymbals & hihats, which sound good, and have much high harmonies......Or it just may be any sample where I can hear distortions (or maybe just invent them ?
Do you have foobar2000 installed on your system with the ABX component?
Also, M/S stereo will make things sound WORSE. Leave it as joint stereo (it is NOT lossy in LAME).
I downloaded foobar2000, but didn't find any ABX component for it (using search on its site).
Is abchr I downloaded a little earlier worse for some reason?
By the way, using abchr, I couldn't hear those artifacts I see... It was only one test as now, but maybe the sample I used wasn't suitable.
I also tried to mix paste (thanx Pepoluan and Greynol for that idea ) samples using Adobe Audition, but it was too difficult to guess how great is the "lossy offset", mentioned by Greynol. Simple comparison of files' lenght did not help me. Is there any bright idea how to find out that lossy offset?
As I see, EAC can determine the offset generated by specific codec, but this operation returns an error for some reason (I tried to determine offset for GoGo and two different LAMEs). What can be a reason?
1) for two same-sounding (for me ) samples, is the one with "nicer" spectre (i.e. most bordering upon original) a better one (concerning quality)? Or it is no judge of quality even for same-sounding samples?
2) For two samples encoded using the same original, do same-looking graphs signify the same quality? (of course, accurate within my eyes )
1) Why qval=3 is now default (at least, when using -V2 --vbr-new)? As I remember it was qval=2 in older LAME versions...2) What is --vbr-new?3) Are there any differences between two spellings: -V 2 (readme file provided with LAME 3.97) and -V2 (found here, on hydrogenaudio.org)?4) Please tell me, does -k really "destroy the quality of files" (like Firon said)? Almost any LAMEs mp3 graph remains same-looking when using this key, and the only difference is lowpass-filter-collapse dissapperance. Or that means nothing again?..
2 - it's a different approach for VBR encoding, we started development some years ago, it will be the default VBR mode for LAME 3.98
3 - no, with single letter options taking parameters you can leave the blank out
But why an old algorythm is default for now? Is the new one still a "flaw design"?

Setting min/max bitrate is not needed in 3.97 when using VBR.Spectral analysis is virtually useless for measuring sound quality.
Hmm... But when not setting minimum frame bitrate, LAME uses bitrate lower than 128... is it good?
You are partially wrong.In low-bitrate, Joint Stereo is really Intensity Stereo. *That* will collapse stereo separation.
Quote from: Firon on 29 November, 2006, 09:27:29 PMAlso, M/S stereo will make things sound WORSE. Leave it as joint stereo (it is NOT lossy in LAME).But isn't JS (when using at LAME, on high bitrates) mostly M/S stereo? Or your mean forced M/S, without using L/R Stereo when it's needed?
Hmm... But when not setting minimum frame bitrate, LAME uses bitrate lower than 128 (on some songs - oftenly)... is it good?
