I don't manage to get Audacity to record something right now (this has happened once before, I tried some things, then it worked again, but I didn't really gather what actually made it work again). I'm working on that right now. I think contrast analysis is what returns average RMS in Audacity.

Uhm, something seems to be off in my understanding: Isn't most of the goa/psy stuff that gets released nowadays already normalized to be as close to 0dB as possible? If that's the case then the loudest theoretically possible signal would be hardly louder than what's already on the cd - and I still only get up to -12 dB.

Mostly I just archive it to the hard disk as a 44.1kHz/16bit wav-file. Sometimes I copy it onto a portable music player, burn an audio cd or put it on a usb stick. I'm planning to upload some mixes to soundcloud or a similar service, as soon as I have some that I feel are worthy of that. 48kHz/24bit might sound slightly better but 99.5% of people wouldn't care about that (assuming there is a service that would host such files) and even I personally haven't bothered with higher-resolution-than-redbook formats so far.

What if it were 100 carnivores? You would save a humand _and_ all those animals the carnivores would have eaten.

So essentially this means recording at -12 dB and then normalizing the result really close to maximum amplitude is more or less the optimal thing to do. And as I understand it from your post, this is the case because if there was the "loudest theoretically possible sound" on a cd somewhere it would put the signal to the maximal amplitude, but not yet into clipping?

I recorded Leftism - Mind Doctor (http://www.ektoplazm.com/free-music/labyrinth-of-your-mind). Screenshot of Audacity before normalizing: Aufter normalizing to -0.01 dB the result of contrast analysis for the upper (left?) channel of the entire track is -13,8 dB.

1. If you knew that they wouldn't be any consequences at all in this life and afterlife would you kill a person? (You choose who). No 2. If you had the power to seduce any woman/man you want and then erase the incident from their memory would you do it? Yes 3. The button question. I told you to push a button and win 10 million dollars, but someone you don't know will die would you push it? No. Unless there was a way to save more than 1 persons life with the 10 million dollars, then yes 4. If you could travel back in time and change history would you do it? No 5. If you could create a clone of you to do all the hard work would you do it? (Clone is 100% human being). No, doing hard work from time to time is good for me 6. If I told you that you could be powerful, successful and rich, but you have to sacrifice your friendship with one of your closest friends would you do it? a.Not your best friend, but a close one. b.You can't choose which one. c.Not with a fight. You just erase your friendship from his memory. No 7. If you had to save one human or 100 animals who would you choose? a. Inteligent animals, no insects, fishes etc. Think dogs, cats, apes etc. b. The human is some random adult you don't know I'd save the human 8. You are a religious leader like the Pope and everything you said is taken by the world as the absolute truth. One day you find out that there's no God, any God and after death we just ceased to exist would you tell to the world or let them believe? I'd tell. Not everything that doesn't kill one makes one stronger. But I think the truth would 9. If you was the first and only human to have the opportunity to live in a friendly alien civilization would you do it? There's no return and you are the only allowed to live there. Probably not. Unless they were _extremely_ similar to humans in all regards, but more evolved: then maybe 10. Listen to Skazi live for 24 straight hours (no earplugs allowed) or have a day with radi on a mountain? radi, of course Saving the animals would maybe be the more moral choice, but wouldn't common sense dictate to save the human, since the death of a random human would on average surely cause more disruption to human society than the death of 100 random animals (intelligent or not)?

Dolmot: What you write makes sense to me. I don't understand this part though: When normalizing in Audacity, would you recommend enabling DC offset correction? I'm assuming it's not possible to introduce DC offset when staying inside the digital realm all the way from the source to the recorded .wav and I'd assume most commercially released tracks would have any DC offset removed already; but could it theoretically hurt to do it a second time (as in: could there be something that looks like DC offset, but is actually intended and/or something different than DC offset)? Exactly this. I have never been mastering my mixes. I don't even really know what mastering means in relation to a dj-mix (as opposed to a studio-mixed album or compilation). When recording an analogue signal, I tend to try to get as close to 0 db as possible during the loudest part of a track, while avoiding signal clipping to happen more often than maybe once or twice per minute (assuming one occurance of clipping is one vertical red line at default zoom in Audacity). I think I looked through everything which had any chance to be even remotely relevant. Probably twice.

The CDj-400s are connected to the mixer (digital out on the cdjs -> digital in on the mixer) by 75ohm coaxial cinch cables, the mixer is connected to the PC per USB.

I don't think it's possible to set the xone:db2 to work at 24 bit instead of 48 bit internally. Thanks a lot for your input, aliendna99!

Thanks for the answers! I don't even know what the difference between normalizing the max peak of a wav and normalizing rms is, mathematically. I guess it's best to set Audacity to record at 48 kHz and 24 bit then, rather than 32 bit.

Yes, that's more or less question 2: I'm not sure if it's theoretically possible to increase the amplitude of a digital audio signal perfectly. If it actually is (which I kind of doubt) then that still doesn't mean the algorithm to do so is perfectly implemented in Audacity. Question 1 would be: Does Audacity receive an 48 bit digital audio stream to work with from the DB2 or a 24 bit stream? The problem with recording louder is that it becomes harder to match the levels of the tracks by looking at the meters of the DB2, since the master vu-meter on it goes [...], -3, -2, -1, 0, +1, +2, +3, +6 db and then there's the top led to indicate clipping. If I record at a louder volume, then I cannot match levels as closely, which leads to greater variation, which leads to a generally lower level after normalizing. Initially I was pretty stressed out about the DB2 delivering -12 db (after all the only reason I got a digital mixer in the first place was to achieve optimal sound quality) and I personally would still prefer around -3 db, but I know how many DJs don't mind playing deeply into the red part of the meters at all, so I guess I can't really blame A&H for not letting some folks completely f' up the sound quality that easily, when the trade off is relatively small...

Hey there! I bought an Allen & Heath Xone:DB2 dj-mixer yesterday and my biggest gripe with it is that when the meters (individual channel as well as master) display +/-0 db, the signal I get when recording in Audacity is actuall at about -12 db. Going by its spec sheet the DB2 works at 48 kHz and 48 bit internally and I assume it receives the 44,1kHz/16bit digital signal from the CDj-400s, upsamples it and then lowers the amplitude by 12 db so there should be practically no quality lost there. I'm just wondering: if I record with the DB2 selected as the source in Audacity, does the software actually receive the 48kHz/48bit signal and convert it to 48kHz/32bit (it is not possible to chooser a higher bit rate than 32 in Audacity) or does it receive "only" an 48kHz/24bit signal (specs say it has 24 bit I/O, but I'm not sure if this applies only to the digital I/Os on the back of the mixer or if it also applies to the digital signal the software receives from the DB2 as a soundcard, instead of the 48 bit EQ)? And also: Do you think Audacitys normalzing algorithm is up to the task? I'm also sending this to the Allen & Heath partner in Austria, so if nobody here has any idea about this, I can still hope to get some infos from them.

I think it would be great if you could tell him to check (t)his thread.

MWNN rocks. I recently acquired Earth Moving The Sun and Moment of Truth. Too bad Teleportation seems kind of expensive and Interstate Highway is rather "meh".

So far I haven't received an answer to my inquiry in this thread. Anyone got something?

maybe make it your passion to find out what hampers your ability to be passionate. or care more about your wish to care more. maybe that's just stupid word-play, but maybe it helps you, I don't know.

Hello! I'm interested in Filteria - Heliopolis Cosma - Simplicity Cosma - Nonstop Shpongle - Are You Shpongled? What condition are these and how much would you want? How much would shipping to Austria be?

Could be that I've heard these scratching noises once, but for me it's this:

Yes, using toothpaste to smoothen out scratches has worked for me before. I guess short exposure to water is not a problem, but it would be constant humidity that could cause damage. Of course. You have to smoke the banana peels while cleaning the cd with toothpaste to get the desired effect.

I have no idea if I should be afraid of death. Nobody knows what's really going to happen, and I haven't made my mind up on it for me, personally. Facing the loss of everything and everybody including yourself, on the brink of death, should be assumed to be the most devastating experience one can have, but maybe it actually feels much more like salvation? And what's with all those neurotransmitter getting released by the brain then, which are said to get one really high? In regards to physical pain, I guess most people who ever were seriously injured in an accident can attest that the shock prevents any pain from being felt at that time.

I am surfing the web probably 80% of the time when I am at home and have no visitors. Easily for 2 to 8 hours a day. It depends a lot on if I'm in the "flow", like at times every interesting new website leads to another 2 of that sort. But I really like going out into the park to play some chess or visit friends and I enjoy that so much and don't miss the interest in the least then. I don't have a smart phone because if it's really important I can use a smart phone of someone else to check something online and it's great to be practically exclusively offline when outside. When I'm about to leave my flat I'm really looking forward to being offline, when I'm heading home, I'm really looking forward to being online. 4chan is great because free speech, but there is so much (real or pretended) hostility there, that I try not to spend too much time there.
