I have a drum track (midi samples) that is going WAY over 0 db. Yet, it sounds great. :D Am I not hearing the clipping? Is this wrong, will I be banished from HR?? :confused:

My engineering skills are mediocre, yet I know the basic tenets. I also know that rules are made to be broken, and ultimately how it sounds is what matters. Is this a common practice? Am I just reacting to it being louder and subconsciously I think "louder is better"? :confused:


P.S. Because of computer limitations I am doing drums in one Sonar project and importing to the other. It is clipping in the original project only. Yes, the waveforms go off the scale when I import it.

how long are the actual peaks?
if there only so long, like measured in samples, then it just may not be audible distortion due to duration.
and if you can't hear it, it ain't there.
this is audio, not pictures.

:p

They are very short, fast transient peaks. Perhaps I am thinking about it too much, as I cant hear anything unnacceptable.

It depends on where it goes over. Internally in the mixer, you can go over 0db without clipping. It will clip your converters and/or a mixdown. To say it another way, there is no clipping inside the machine. Clipping only happens when you mix it down or try to squeeze it through a converter.

There could be a couple things going on. Louder will always sound better. You can test which actually sounds better if you import the mixdown back into your session and A/B them at equal volume. (meaning turn down the track that is clipping and make it the same volume as the mixdown) That's the only way to see which is 'better'.

Another thing you might be reacting to is the limiting. When you digitally clip something, you are essentially running it through a brick wall limiter. You might like the sound of the drums limited like that. You could get the same effect by running the samples at sane levels through an L2.

Lastly, distorted drums can sound cool.

The only real problem you will run into is you are going to be mixing too hot. This can lead to distortion on things the don't take to it as gracefully as the drums do.
 
It also depends on which piece of kit's causing the clip.
If it's the kick, it turns the low freqs to mud.

Cyms always tend to peak a little.
If it's running consistently in the red,
turn it down until it goes occassional.

Don't try to take a pre-mixdown or pre-master
to Redbook sound levels.
Generally, trust the meters (depending on the mixer),
not your ears.

One thing most home recorders aren't aware of,
Digital 0 (unity gain) isn't always the same as analog 0.
In digital, we always keep studio faders at -03.

A Radio Shack sound meter's a good $35 investment.
Set it on 90, try to stay around +-83 db.

Nothing should peak, even a little, if you are recording at the correct levels.

Redbook says nothing about signal level.

This has to be a joke.

Digital 0 is not unity gain, they aren't even related. You are correct that digital 0 and analog zero are not the same.
FKA1 said:

Why?
The fader doesn't change the recorded level. If you clipped the converters, you have already screwed the pooch, the only thing you are doing with the fader is turning down the clipped signal.

Recording levels are completely independant of montor volume.

I guess my question is: "Why not"? If I cannot hear it, either:

A. I am incapable of hearing it

B. It is not there

Is there a particular reason of why I should NOT do that? Actually I am explaining this wrong: I AM recording at the proper levels. It is the processing (compression and reverb) that puts it over the top. Certainly I can turn it down, I am more curious as to why. If there is something there I am not hearing, that is certainly a possibility. Maybe I am confusing loud with good, I have no pretentions of being a skilled engineer.
 
FKA1 said:

What does this mean? Everything "peaks". Do you mean "digitally clips"? If so, saying that cymbals always tend to clip a little is wrong. It totally depends upon the miking technique, whether you're talking about a crash or a ride, the drummer's playing style, etc.

And that's just talking tracking. In the mix it depends entirely upon the timbre of the mix, the genre of music, the spectral balance between instruments, and even the mood of the engineer/producer. There is nothing that says that cymbals should peak higher in the mix than anything else.

If you're talking about going above 0VU on the analog side (going into the VU red), then, sure, it's entirely possible that you might track some cymbals that hot. But the same is potentially true for every other instrument; there's little special about cymbals there.

Watch your terminology there. In standard parlance, "digital 0" refers to 0dBFS, not the "0" or unity gain position on a digital slider.

As for evrything else, Farview has it right (though I won't come down on the school, just the loss of the forest for the trees.)

Way, way back when I was in sales (over 25 years ago), we had a "trick" that was a slam-dunk for selling equalizers for home and car stereos. We simply only boosted the various frequencies (except the mids) and didn't cut any frequencies, even if they sorely needed them. With the exception of audiophiles or people who's ears simply knew better, everybody thought the EQ sounded fantastic, even if it was a piece of crap and even if the EQ curve was pure fantasy. Why? because it increased the volume.

Same with loudspeakers. Any time I wanted to sell a pair of ESS loudspeakers, I'd A/B them with the Advents, playing the Advents first, even though the Advents were a far smoother and more accurate - actually better-sounding - speaker. Why? Because the ESSs was a higher-efficieny speaker; it put out more SPL per watt than the Advents did and was automatically louder without even having to touch the volume control. And people translated that into better (while we were holding our noses behind their back.)*

Like Jay said, David, A/B the mix with the clipping and without the clipping. Use the same amount of compression and verb, but just hold back on the comp makeup gain and/or the track trim volume to keep the clipping away. But A/B them at the same SPL playback volume. Then use that A/B to determine which sounds better.

If the clipped track does honestly sound better to you, then run with it. There's no commandment that says if you clip you're going to hell :). BUT, if it sounds a bit worse, of even basically the same, then back off and do without it. Remember, it's not how it sounds solo, but how it sounds in the mix. And if you are using more RMS energy in a particular track than necessary, that leaves less mixing room for the rest of the tracks.

G.

*It's this kind of BS that goes on all the time in sales, which is why I left sales a loooong time ago ;).

Also, Dave, I just remembered (I think) that I left one of your PMs from yesterday unanswered. I'll answer it shortly... :)

It all goes to proper gain staging. Everything is designed to work within a certain window of signal strength. As soon as you get the levels out of whack in one spot, you end up having to compensate for it somewhere else. In the analog world, it was more of a problem because too much signal would lead to distortion and too little signal would bring you closer to the noise floor. (which would lead you to turn the signal up later and the noise floor would come up with it). That's the reason not to do it. If artistically you want to do that, go ahead. There is no law against it. But if your goal is to record and mix with the cleanest signal path, good gain staging is the way to go.

There could be many reasons why you aren't hearing the distortion.
1. Your monitors
2. Your room
3. You are hearing it, you just like the effect
4. You just don't know what to listen for (I used to have the same problem., Once I had it pointed out to me, I heard it everywhere) Again, listen to a clipped and non clipped version side by side at equal volume, you might hear it then.



BTW, compression only turns things down, you have your makeup gain set too high if it is adding level.

I'm not trying to come down on the school, but they obviously haven't done their job with FKA1. This stuff can be hard to wrap your head around, but they are an audio school for goodness sake!!! They should be better at explaining this than we are. (or someone needs to start paying us)

Yeah, That's true.

Hmmmm....the only person getting paid for our stuff right now is Dragon. :eek: ;) . We'll have to work on that ;).

Thanks for the help fellers. :cool: I have come to the conclusion that it is not much different. If I A/B tracks, I really cant tell much of a difference, therefore it doesnt seem to be worth it just in case someone CAN tell. One of my legions of adoring fans may hear it. :D :rolleyes: :cool:

at the correct levels.

My experience (and many others) disagrees.

OOO, the local geeks rideout to poke the new guy w/ a stick! LOL!
First off guys, apologies for underestimating.
Up until now, the only posts i've caught are filled
w/ M-audio monitor users, and a young guy trying to sort his
"making a record problem" w/a sm-58 and an overhead.

I'm an artistic producer, a pair of ears.
I generally leave the geeking to the geeks.

The last project i did is at over 50 P$4DL sites,
hit #1 45 times on Broadjam, Besonic, Weedshare, Mp3.com.au...
I use the artist preferred studio in my area, take the music home/do
overdubs on a Tascam DM-4800.

Redbook says nothing about signal level.
Of course not. i was referring to perceived loudness,
trying to send levels to CD loudness pre-mastering.
This has to be a joke.
Not at all!
A pair of ears are only as good the monitoring system.
"Trusting the ears" is as good on a cheap set of home monitors
or headphones as a pair of Blue Skys ?
That's ridiculous.

Digital 0 is not unity gain, they aren't even related. You are correct that digital 0 and analog zero are not the same.
Sorry for the wording, i didn't mean to imply that they were.

As for the sound meter, i was referring to of course,
"at monitoring/ mixdown".

I'll try to watch my terminology in the future.
Are we good?

Sure, we are good. :D I read every post and weigh anyone's advice and experience.

In this case, I am seeking out the geeks. :cool: My question was more of a technical one, I think I got the correct answers, mainly this:

2. Your room

To me this seems right. I may not know what to listen for. I am very comfortable with my musical abilities, I know what I can do and cannot do, and am always trying to learn. It is VERY possible that I may not know what to listen for since drums are not my area of expertise. Glen and Fairview (and others) have consistently been a great source of knowledge in sharing their considerable expertise here.

BTW welcome to the forum new guy. :)
 
Although I am a big fan of distorted drums (and just mangled audio in general), I would strongly advice against clipping, or recording too hot, or clipping your preamps or analog inputs (sound design/sample mangling stage not withstanding).

I used to record and mix too hot too and always complained that my mixes sounded small and strangled. As I've lowered the levels (both during tracking and mixing), my mixes have improved quite a bit and have more 3 dimentional feel to them.

Leave the loudness for the mastering stage.

As an artist, you can do anything you want, including screwing up the gain staging to achieve an effect. However, that really doesn't qualify as good advice to someone just trying to do things "right". If the question was "what creative thing could I do to my drums to make them sound different?", then you would be right on track.

I've done work for major labels with worldwide distibution (in stores, not just the internet) over the last 20 years. I've worked with Black Sabbath, Bon Jovi, skid Row, Manowar, etc... And I recorded the most popular drum sample collection for Drumagog. I have sold thousands of them all over the world. They are on every continent (except Antartica).

Congratulations on your mp3 hit.

Level meters aren't going to do anything but tell you what the level is. What your audio looks like means less than nothing. Everything else is your ears, if your monitors lie to you you're screwed.
 
DavidK what software are you using? Some software packages automatically limit so you don't hear the clipping when you go over 0. for instance, Sonar use to have an overflow setting now I think it just does it automatically.
