Sample Delay and HAAS Effect

Hi. In this video, we're gonna talk about delay and how to use delay in logic pro TEM. So when I say delay, you might be thinking of stereo delays, feedback, delays, tape delays, the sort of delays that actually repeat the signal and feed back to itself. But that's not what I'm talking about right now. I'm talking about the most basic delay which actually just delays the signal by a certain amount of time, whether that be in milliseconds or samples. The reason we might do that is to correct phase issues. So when you hear the word phase, just think time, so phase is time, a really common reason to fix phase issues are when you are mixing multi track recordings and the microphones for each instrument were at different distances from the instrument that I was recording, especially with studio drums or live drums, those differences can cause phase issues, cos lots of the instruments will bleed into each other's mics. Those differences in phase brackets time can cause comb filtering and oth...

er problems. So it's necessary sometimes to adjust phase on different tracks. Sometimes it's just necessary to adjust a phase if the vocalist was just a little bit slow or just a little bit fast in the performance amongst many other reasons as well. The simplest way to do that is to use the sample delay plug in. So I'm just gonna go to the end of my track here and under the plug in menu, I'm going to choose delay, sample delay. So here we are. So we have a few options here. We have a delay left, a delay, right, and a link. So I can actually change the phase of the left and right channels independently, which can be quite useful if you find yourself in a situation where the right channel or the left channel is slightly later than the other channel. And that correlation issue needs fixing. You can solve that problem really easily by just delaying one of the channels until they match in phase. Right now, I'm adjusting the phase in increments of samples. So a sample is basically all of the snapshots of the waveform as it exists in digital. It's the smallest increment that you can adjust phase by because the samples are what represent the waveform inside the computer. However, you might find it necessary to adjust in milliseconds. Sometimes you might know the amount of milliseconds in theory that you need to make adjustments by based on measurements that you've taken in the room when recording what have you. So you have two options there, the different units in which to adjust phase So let's experiment with a couple of things. I'm just gonna play the vocal track that I've got here, rushes past my face and through my hair for the briefest of moments, I feel like I'm flying. OK. So if you're listening in headphones or if you're listening speakers, you'll find that this vocal is dead center in the middle of the mix, which is cool. But let's say that I wanted it panned to the left a little bit or pan to the right now. Obviously, I can just pan left or right. But if I pan, I'm not actually getting any time differences between left and right, which is actually normal in nature. If you speak to me from the right hand side of me, your voice reaches my left ear later than it does my right ear and vice versa. When we pan, that's not necessarily happening that effectively. But if we delay one channel behind another channel, it can create that effect and that effect is known as the haas effect. So let's try it out. I'm going to switch to samples now just because it's a smaller increment and then I'm gonna delay the right channel every so often until the signal seems to move to the left. I'm gonna keep the panning in the middle though. So let's see how this works. She's past true. So you can hear that immediately. You can especially hear this on headphones as I dialed up the delay on the right channel, you could hear the vocal, just pan to the left. It's very realistic. It sounds a bit more realistic in headphones than panning, generally speaking because with panning, you're not getting a time difference between left and right. But with this, you are getting a time difference and that's what we are used to in nature. Otherwise, if you are just trying to fix phase issues and you don't want a difference between left and right, you just dial it down, you link left and right and it delays both channels by the same amount. So that's how we use sample delay when mixing in logic. Pro see you in the next video.
