How to (best) hear yourself when tracking vocals
Do you own a computer soundcard with direct monitoring?
No, I don't own one, but I did review the TASCAM US-122 with direct monitoring, a fully analog path between the input jack and the headphone jack. There's essentially a four-input mixer inside the case. Two of the inputs are from the returns from the computer (which are of course delayed) and the other two inputs are from the mic preamps, with a switch to put a single input in the center if that's what you want to hear. A pot adjusts the balance between the playback and input. Works fine. Zero measurable delay from the input jack to the headphone jack when in the "no latency monitor" mode. At least less than 0.05 uS, about the best I can resolve with my oscilloscope. That unit is a different animal from most interfaces, what you're talking about is parallel monitoring and you can actually do it on a Soundblaster. I'm talking about soundcards that do monitor switching, so we are talking about different animals here. And you're still going through the converters. There is still latency. Anytime you want to prove my point, I'll be here. No contest there. The 400F has "low latency monitoring" which does not depend on the ASIO driver running on the computer. It does not have direct monitoring. "Low" is a very indefinite number. I don't know what it is for this unit, as I've said. But I know it's greater than zero. It's a mixer with a computer interface, can it do "input to tape" monitor switching? NEVER sum two sognals, one of which is delayed by a small amount! Don't you know that causes comb filtering? OK, next time I sing, I'll stuff a rag down my throat to block the acoustic path through my head. If it were so much of a problem, then why don't more people complain about it? You STILL don't get what I'm talking about. I'm not talking about summing electrical signals here, I'm talking about summing acoustic pressure waves - one coming from the earphone and hitting the outer surface of your eardrum, the other coming up your throat and hitting the inside of your eardrum. Since both come from the same source (your vocal cords) but through different paths, they will arrive at your eardrum at different times. If you have the same pressure pushing on opposite sides of the eardrum at the same time, the eardrum won't move - hence you'll hear no sound. That's an extreme case of course, but it's the mechasim at work here. Mike, I know exactly what you're talking about, I'm not arguing that... what I am arguing with you about is the degree at which it becomes a problem. They aren't combined at a close enough amplitude to be a problem. That might be true, or it might not. It depends on how loud you turn up the phones. The reason why this isn't a problem for many people in practice is because they want more volume in the phones. This is why I suggest that you try an experiment where you take the time to vary the headphone level as you're talking or singing rather than just set it so that the phones are pretty darm loud like you or your clients like it. Mike, I've been monitoring through the machines for years, so have a lot of other people. Why do we not have huge problems? Because individuals are all different. I don't work with rock singers who want their voice really loud in the phones. You're saying this to the big "western swing" engineer? :-) There is nothing wrong with my understanding. They are NOT identical! One of them is being filtered by your mouth and one of them is what resonates through your skull, they are pretty dissimilar. They're dissimilar in spectral power, but that just means that the amplitude of some frequencies are different. Some will be cancelled to a greater degree than others if the time relationship between the two is such that some frequencies will be out of phase (which will almost certainly be the case). We agree on this. |

This was standard practice back in the fifties and sixties when studios weren't providing sophisticated monitor mixes, but these days it is hard to get people to do it. Funny thing, it works a lot better than most of the fancy monitor mix hardware. Whatever happened to the Roland matrix mixers anyway? --scott -- "C'est un Nagra.

It is? You can? I guess that when there's more than one way to monitor, you have to come up with a name for the old way. I'm talking about soundcards that do monitor switching, so we are talking about different animals here. I'm not aware that any do. ASIO has hooks for that, and when the driver tells the card that the program is in "auto monitor" mode, the card can do a digiital loopback, sending what's going out to the computer back through the card's D/A concerter - about 1.5 ms later than it went in. A tape deck has a relay that connects the input jack to the output jack. The output goes out about 0.0000000000000000000000000001 milliseconds after it went in. The 400F has "low latency monitoring" It's a mixer with a computer interface, can it do "input to tape" monitor switching? It's a DIGITAL mixer with a computer interface, with the inherent delays. I don't think the 400F does real monitor switching. One input to the monitor mixer is a stereo return from the computer. You mix what goes out that stream in the DAW. The 400F's monitor mixer is primarily an input mixer. You can't bring 8 streams back from the computer and mix them in the 400F. If it were so much of a problem, then why don't more people complain about it? LIke I said, it isn't a problem if your headphone volume is high enough. More people want the headphones turned up than turned down, so most people are simply not aware of the effect. Of course it could be that their voice sounds more natural to them BECAUSE it's loud enough to swamp out the comb filtering effect. If you want a second opinion about whether this is noticable, ask Bob Ohlsson or John Klett. Both have more than a little studio experience, and both have written extensively about monitoring and what can be wrong with it. Mike, I know exactly what you're talking about, I'm not arguing that... what I am arguing with you about is the degree at which it becomes a problem. Well, any time you want to argue degree, you'd to have a diffrence of opinion. How rare do you like your steak? |

I'm not sure what Roland you're talking about but the Avion and Hear, albeint digital, let a singer create and control his own mix. The Oz Audio headphone mixer was kind of a small scale "more me" mixer with a main stereo mix input, a reverb return, and four dedicated inputs that could be mixed with the main stereo input, to four separate headphone outputs. Mackie has what appears to be (to the best of my recollection) essentially a copy of the Oz as their HMX-56 headphone amplifier. |

This is somehow much more of a practical problem when the two signals are combined in one speaker cone (or headphone). When the sources are physically independent, the brain copes remarkably well. Thank you. Mike and Hank have the modern recording world coming to a halt because of this "problem" which hasn't been an issue since digital machines came out. Bull****. We get araound it, using what's between our ears. It is not a problem because we make it not a problem. But we also don't pretend it doesn't happen. Though, come to think of it, based on much of what I hear, bringing "the modern recording world" to a ****ing halt for some wake up calls might make good sense. There's enough shiny **** around to last for minutes, such is its worth. -- ha |

One to my recorder and one for monitoring? That would be fantastic! I'm pretty sure that'll work fine. I downloaded the .pdf twice, but both times it somehow got corrupted. If one wasn't supposed to use both outputs, I'd expect Yamaha to state that in the docs somewhere. Have you read any bads news of that kind? g -- ha |

The off-the-cuff remark about "eight layers of software" was a poor choice of words. It's only recently that one could reasonably configure a system for relatively low throughput delay (I prefer that phrase to the use of the term "latency" in this context). Even DA88s and ADATs held up the signal long enough to be noticeable. Even now, *most* systems do enough buffering and processing that *most* people aren't getting their signals back to them in a couple milliseconds like it seems you are. I don't have the luxury of being able to test the affects of 1.5ms throughput -- my choices are instantaneous analog or slow digital -- but I suspect that you're right about signals coming back that fast being good enough to not screw up a singer. Like you said, it's the equivalent of standing a couple feet away from the mic. How was I acting like a dick? Quotes please... You made some remark about Mike and Hank, suggesting that they were doing a Chicken Little. It struck me as insulting. Still, I came on way too strong in my reply to you.

If you routinely work in a way so that the problem is masked (a loud headphone mix) that doesn't mean the problem doesn't exist. It only means that it doesn't bother you or your clients. That's fine, too. |

Who cares how the delay is created? It's still a delay. The quest for "low latency drivers" is an attempt to add as little as possible to the delay through the converters. If you were working on a pure analog system, you wouldn't put the singer's voice through a 2ms delay and send it back to his headphones, would you? That's what you're doing when you monitor through the converters. |

people aren't getting their signals back to them in a couple milliseconds like it seems you are. I'll admit, I'm spoiled with the RME stuff. For me, they have been the only way to reliably get your DAW to function like a tape machine, but yes there is converter delay and yes I can tell that it's there if I try.

throughput Do you have a delay unit (real hardware, not a plug-in) that goes down to 1.5 ms? If so, do this: Plug a mic into one channel of a mixer. Use a pre-fader send to send the mic input out to the delay. Bring the delay output back into a mixer channel and pan it to the center. Plug a set of headphones into the mixer's output and put them on. If the delay unit is digital, done even bother to set it to 1.5ms. Set it to 0, the converter throughput will be around 1.5ms. Unless of course the unit compensates for it's own converter latency, which I would doubt it does. It should be easy to test on a workstation. They ARE useful for some things :-) |
