Question from Owsinski's Mixing Engineer's Handbook

Talking about Level Setting Methods, Ed Seay is quoted as saying "Usually a good place to start is the kick drum at -6 or -7 or so, ..."

When he says -6 or -7, is he on the same scale we are when we're looking at our peak meter in Sonar?

As always - thanks,
Sam

    No, he is talking analog days of mixing where you could start at -7 and still have enough headroom at 0db once the rest of the mix is added. If you had transients over that level it sounded good because the circuits were saturated and imparting a pleasant sounding distortion.

    In the digital world 0db is the end of the road so you're safer to start around -12 to -16 or even up to -24db on the kick so that you build in some headroom for the mix. This way you stand less of a chance of hitting 0db with your transients once the RMS value of the mix is set. The challenge is creating that nice saturation for the upper RMS and transients that analog provided. There are many tape saturation and tube emulation plugins you can drop in at the track or buss to get that vibe.

    It's also kind of meaningless in a way since it would depend on how prominent the kick is in the song. In some song styles it and the snare may be the highest peaking things, in other styles the vocal may very much be more dominant, or huge guitars, or whatever it happens to be.

    Ultimately, in a DAW, it's not much to worry about anyway. Get a rough mix up. If it's coming up too high or too low, just select all the faders and pull them down or up a smidge. It's not like an analog console where you might mess up carefully set up balances if you did that. In the DAW you can move them all as one very easily.

    Continue mixing, and then if necessary adjust again as you refine it.

    Also you can do a mixdown of the track and look at the resulting wave form and figure out where the peaks are occurring. If your peaks are coming from a small number of unusually high peaks (not unusual), then go just deal with them in the tracks that are causing them. A wee gain envelope dip and it goes away. You would have ended up putting a limiter on the track to get rid of them at the end anyway, so might as well deal with them much more cleanly and transparently at the mixing stage and get your levels adjusted during the mix so that they are closer to the final product.

    Re:Question from Owsinski's Mixing Engineer's Handbook 2012/03/25 17:58:17 (permalink)
    If I record audio tracks, and create MIDI tracks at -14, and I need to raise something in the mix, I would move my fader above zero. Is that normal practice? Or, start with faders down at -6 or so and use the trim control to get me back to -14 on everything to start?

    Am I way off track and do I make things too complicated?

    There are some schools of thought around starting with your trim in the -6 or more position across all your tracks and busses, basically put 6db of headroom on the mix at the get go. Just a thought.

    Specific to your question. Keep your Master Buss on unity (0db) if you need more volume, turn up your speakers. You are dealing with bit resolution in the box and pushing that fader above 0db could have ramifications to your gain structure going into any sends. It could sound great balance wise but you might be slamming some plugins. You should spend time with a radio shack meter and get your speakers set for the room at the right volume, then you won't need to push the track fader up and you can mix in the -24 to -6 range without overdriving individual channels.

    Hope that answered the question.

    The primary reason to get to a specific place on the master bus is because you've set up a calibrated monitoring system (like the k-system) which requires that you be at a particular spot on the master bus to get the appropriate SPL level in the room.  Otherwise, other than leaving sufficient headroom, there's no reason that it needs to be at any given level per se. But having a calibrated monitoring setup is a good thing, so you probably want to do it.

    If you are worried about pushing up tracks because you have level sensitive processing on the buses, then start with your main buses down a little so that you have leeway to push them up. Ultimately, in most mixes, you are going to end up with every track going to some bus, and some of those feeding higher level buses, so that ultimately you end up with a handful of main sub-buses that are feeding the master bus. You can start with some extra leeway on those. Since they ony feed the master bus, they won't affect any downstream processing if you push them up.

    Well, they may at the very end if you add overall mix level stuff on the master buss, but by then you should have your levels pretty well worked out.

    Re:Question from Owsinski's Mixing Engineer's Handbook 2012/03/25 21:12:09 (permalink)
    Dean, I was concerned about needing to balance levels, and starting with track faders at zero, I wouldn't have upward room, if indeed going over zero was not "the thing to do" per those that are knowledgeable. Even if that was "allowed", I'd only have 6dB to move up. So, I've worked it out where I start with the track faders down at -12 to start.

    I do route everything except the (MIDI) bass guitar to go through buses to the Master Bus.

    However - I didn't think through how  those buses figure in, and not knowing how this will all sum up in the Master Bus, I just thought I cross that bridge when I get to to it,  so now that you mention it, I will start with those down a little.

    I'm sure you can see I'm inexperienced in this, but I am enjoying learning and experimenting. I'm trying to do things consistently, leaving myself level adjusting room, and changing my process as I learn how one thing affects another.

    Thanks very much for your help!

    I think the point of that section is to start with the loudest instrument and build the other levels in relation to it. If you didn't do that, you'd run out of headroom real quick.


    All else is in doubt, so this is the truth I cling to.

    Yes I think you're right bitflipper. I wasn't so concerned about the kick drum, I'm mostly trying to get a consistent way to start my mix. That's why I wan't to know, based on Ed Seay's start point, where is that on our Sonar meter. Glad you saw this thread. I'm always interested in what you have to say.

    Like pretty much all newbies you are stressing for fixed answers to things that have no fixed answers. You can't be wrong because there's no really right answer. Just start the mix. See how it turns out. If it's not optimal, then adjust. After you've done a fair number you'll start seeing what works for you and your type of music.

    Just get a rough mix with nothing but balancing track levels. It's easy to make broad adjustments at that point to get yourself about at the right levels for the overall mix. Then work from there to apply processing. If you just get completely twisted up, throw it all away and start again. Do that enough times and you'll get there eventually.

    There really isn't a short cut for that process, unfortunately. More and more lights start slowly going on over time.

    I'll take that good advice Dean. I have a reputation of spending sooooo much time getting ready to do something (learning/figuring out a process) that I don't get to the goal.

    You might/will also benefit from starting to balance your faders with everything in Mono.

    Talking about Level Setting Methods, Ed Seay is quoted as saying "Usually a good place to start is the kick drum at -6 or -7 or so, ..."

    All these engineers are referring to real VU meters and the figures mentioned here are definitely nothing to do with peak readings. They are rms VU readings. You can mix to a certain extent with VU's but it is only a guide. Ultimately you need your ears to tell you how a mix is sounding. But VU's are a good start.

    For those who don't have them the Klanghelm meters are pretty decent and cheap too.

    http://www.klanghelm.com/VUMT.html

    You can mix of course without VU's but it is much better to mix with both VU and peak metering. Once you get a decent VU into the equation then you can adopt the K system of level setting on tracks and busses (and monitor levels of course) and you will never have a problem with levels ever again! Also with VU's you can leave your master buss and all sub busses at 0dB or unity which is where they should be and should stay. There is NO need to ever move them in fact.

    If the drums are a bit too high or low, then there's no reason not to adjust the overall drum bus fader. It makes absolutely no difference in sound quality. It's not like an analog console. If you wanted to automate the drum levels, you'd almost certainly automate the drum bus output, which means it won't stay at 0dB.

    As already mentioned, if you have bus level processing, it wouldn't make any sense to adjust all the individual drum track faders and then turn around and adjust all of the level sensitive processing on the drum buses. It would be vastly easier to just adjust the drum bus levels.

    So I'm not sure why you would argue that they shouldn't ever be moved. If that were the case, they wouldn't have faders to begin with. I've certainly watched a butt load of documentaries about making great albums and none of those folks seemed to have a problem with adjusting bus faders even on analog consoles. One of the fundamental reasons for having them is to be able to adjust the levels of groups of tracks simultaneously, which requires moving the faders.

    Yes I agree with you Dean. I too think that buss faders are there to be manipulated for sure. I suppose I was referring to a situation where if they were right down at -20 (or right up at +8 dB etc) or something then I would re evaluate track levels being sent to them.  And with digital unlike analog it is OK to send higher levels to a buss fader and pull the buss fader down a little to compensate without any loss in quality.

    I still think the master fader needs to stay at unity though, slight adjustments there maybe OK but by keeping the master fader at unity it keeps you in check with everything else that is being sent to it either from tracks or busses.

    What I have found is that when you work with VU's a lot, the buss and master faders very rarely get moved from unity (unless it is an automation move of course) This is because the VU is showing you the real underlying power of the signal present unlike a peak meter.

    I did want to add that using VU's to mix can be a bit hard as well because the ballistics of the meter will effect whether a kick is going to reach say -6 or -8 dB etc. And also the power of the kick. ( it could be a very wide open 808 kick or a very sharp short rock kick with lots of damping inside etc) The Klanghelm meters are very good because the ballistics are fully adjustable unlike a real VU meter. (both attack and release times)

    But for the OP if you are reading about famous engineers referring to levels here and there they are most often looking at a very expensive set of VU's. VU's are still present in nearly every professional studio and always present in mastering studios.

    droddey your comments reminded me of when I first started mixing in the box. I just kept pushing them faders into the red thinking there was some kind of magic coming. It never showed up.

    I wasn't advocating pushing anything into the red by any means, so if anyone took that from what I said then I was misinterpreted.

    Sure, that makes sense. I was talking more about smallish adjustments. It's fine to do anything to them just as a way to quickly evaluate balance changes and see how you might like it. But it would be kind of ususual to end up with bus faders way down low in the actual mix.
     
    I guess one reason you might do it is so that you can drive something on the bus hard, but you don't really want the resulting output to be very prominent in the mix.

    I like to start setting my mix levels at the loudest (busiest) part of the song. Once you have that section of the song nailed, doing the rest is much easier.

    I usually start around the --6 or -7 area too. I have learned through trial and error that extra headroom makes a huge difference.
