Ciao Dibrom, i'm the italian who speaks english bad yet !
I know you often write that MPC extreme is 99,9999 times transparent out of 100 times.
Can you write here your personal classification about the quality of lossy codecs, using transparency percentages, please ???
For EXAMPLE :

1- MPC insane 100%
2- MPC extreme 99.9999%
...
8- R3mix...??%
9- ?? ??% ...etc etc ...

I'm interested to MPC (all settings) MP3 ( dibrom's and r3mix settings) and OGG.

Thank you Dibrom: you are teaching me so many new things !!!!!!

LOL!

Sorry for my bad english...but...what does LOL means ?

It means he's "Laughing Out Loud", which can be interpretted as either a) rude, or b) your comparison of 100% and 99.99999% was actually funny since there's really not that much of difference between the two. Personally, I got a chuckle out that myself, so I don't think ff123 was trying to be rude or sarcastic.

Now I'm LOL at my reply.......

LOL really.. But i love taking part in some totally unscientific studies every now and then, so maybe you wanna hear my guess:

1- lossless - 100%
2- MPC insane - 99%
3- MPC xtreme - 98%
...
20- MP3 --r3mix - 85%

My take (remember these numbers don't really mean anything ):

MPC Insane: 99.99%
MPC Extreme: 99.9%

Vorbis: Not certain, but I'd estimate with the GT modes, and on more normal music (pre-echo is still some of an issue but its much better with RC3, close to AAC now) around 95-96%

AAC (PsyTEL): 97.5%

LAME --r3mix: 60-70%
LAME --alt-preset standard: 85-94%

These are really just very rough guesses, with a bit of personal experience mixed in. They are hardly objective at all.. but that's obvious If you just want my opinion, that's probably about where it's at.

Thank you Dibrom...but what about MPC standard ???

Ok, ok ! I know very very ( and very ) well that questions like the one i wrote yesterday are absolutely not scientific !!!


LOL !!!

Bloody hell, I thought LOL meant "Lots of Love!!!!!!!!!"

I could give you lots of love.

Really? You think ogg is superior (more tranparent) than --alt-preset mp3? I've never done any listening tests with ogg, partially because I've been told that the general concensus is that ogg's quality is inferior to lame with a decent preset. Do you disagree though? Hmmm... maybe I need to start testing ogg myself.

Yes.



Yes, whoever told you that was wrong.. unless perhaps they were using a really old beta. RC3's quality is very good.. approaching AAC fast.

Hmmm... well why then is so much effort being put in by yourself and others to improve mp3 when there are better free alternatives available? psytel AAC and mp+ are both non-Free, so I figured that's why they are not too widely adopted... but ogg is Free in all senses of the word, so if the quality is there, what reasons are there to still mess with mp3?

And pardon me in advance if this is a newbie question

Because MP3 is still widely used and there is still a lot of interest in the format. Also, it has by far the most hardware support of any other format at the moment.



MPC is free.. as in beer, maybe not free as in speech, but that doesn't make it non-free, it just makes it non-Open Source (the encoder, the decoder is totally free)

Vorbis is also undergoing some very heavy development and changes still. I do help with Vorbis in ways I can, by pointing out flaws and discussing certain issues with the developers (I had a nice chat with Monty today about some issues for example). Once Vorbis hits 1.0 and everything becomes more documented, then I will start to play with it some more.
