Hi,
I know somebody who believes that he can hear the difference of a v0 lame and a wav in 100%. Probably he didn't do a abx-test yet...

Now I just wanted to show him a topic with all known audio rumours. Well I think that 'rumours' isn't correct word to search because I didn't found it. And I'm quite sure that I've already seen this topic here.

Does somebody have the link? Or another word I can use for searching?

Thanks

That is not a rumour. That's either placebo or some pretty amazing hearing.

Thanks. Yes, I know it isn't a 'rumour' but I didn't find the correct english word as I speak german.

Placebo is propably the correct word to search with.

Big_Berny

Maybe he has golden hearing. I've known a few people in the radio and recording business that can tell the difference. Albeit not with 100% accuracy. Point being, if there wasn't a difference, why have lossless codecs then? Lame overall does a pretty dang good job. But its not 100%, hence the word lossy compression. I say just leave him alone. If it makes him happy, placebo or not, its his hard drive and his music.

I think you may be looking for audio myths.

Well, lossy doesn't mean that you can hear a difference. Because there always are some informations which you don't hear/need.

The reason for using a lossless codec is that you then can be sure that there is no difference. Lossy codecs always can have a 'bug' and create artefacts in some special cases.

Perhaps something like common digital audio "misconceptions" or "myths."

I don't know of a thread devoted to these, though it might be useful to have a wiki page devoted to the more common ones (like lossless and joint stereo) that always seem to crop up in new members posts. It could link to the existing wiki pages devoted to specific topics.

Isn't that what a FAQ is for?

Yeah, maybe the topic doesn't even exist, only in my head.

But this topic also shows some myths: http://www.hydrogenaudio.org/forums/index....showtopic=31869

Thanks all.

Ah, touche!

IMHO it makes more sense for a FAQ to be integrated as part of the wiki rather than strings of discussion topics, though I realize implementing this would be quite an undertaking. I noticed that pepoluan started to migrate some of the stuff over to the wiki here, I'd be willing to lend a hand in continuing this if there's interest (I'm decent a organizing things but have no experience in wiki creation/editing).

Exactly my point. I said earlier:


Theoretically speaking lossy codecs are not 100% perfect. Therefore there can exist audible differences between -V0 and .wav. Keep in mind I'm not taking into account artifacts and problem samples. In reality however audible differences exist only in very rare cases. And when they do, only the most trained ear can pick up on it. But thats the whole challenge of a lossy codec isn't it. To decide what information is not "needed" so you can save more disk space.

If you're friend really said "I can hear a difference 100% of the time," I say bogus. If he says he can hear only hear the difference in 1 song out of a few hundred...I would be more prone to believe him.

@spockep: You're completely right.
I just told him to visit this forum and to do a abx-test. I hope I'll ever get a message from him.

Big_Berny

ABX is the great equalizer. If there is clearly a perceptible difference then the user will be able to discern a difference during the test. It's what seperates real audiophiles from audiophiles IMHO.



There aren't too many people that have the time to write countless wiki pages. I would love to bust out two/three guides a week to be honest with you, but then you need to decide what information is important it takes a long time. He did do a great job with that none the less.

Yeah, I (a) acknowledged up front that it's no easy task and (b) offered to help. It was a constructive suggestion, any inference that I was criticizing the work of anyone here at HA is completely your own.

ONCE if anyone can download 400MB in 3 minutes from any place in the world, and ONCE some lossless format is promoted to be on popular hardware players, MP3 will be over. Then perhaps we will never need to go back to this discussion again!

And now Sony launchs one hard drive with One Terabyte of space and Maxell are "making" projects of one media what suports 1,6 terabytes of data in one layer, lossy will be over but this will take some years.These products will be very expensive and come to be popular and cheap I think it will take so LONG time at the point of 90% of people who have PC's buy them, lossy will be over but will take a LOT of time maybe an 10 years.And who won't have your "lossy" files just for fun??

Once 400 Mb per 3 minutes for everyone will become reality - not only MP3 may become dead but any lossless codec too.
But IMHO it will not die:
1. Nobody will decode stored MP3's back to wav.
2. Storage amount of audio players is also a factor.
3. There will remain slow chanels - cellular and others.

Maybe this will help:

Cellphones are rapidly increasing in speed. HSPDA gets like 3mbit/s now, and they're planning on raising that to 14.4 in the future. And HSOPA is supposed to be rolled out in 2010 in Japan, further raising speeds (to about 40mbit/s)

Great! I'm relatively good at wiki creation/editing, but I despair on seeing the current FAQ thread. Remedial Sound, just dump it with proper paragraph breaks on the wiki and I'll format it.

Thankieee!
