Assigning inputs and getting signals

From: Digital Audio Principles

Video: Assigning inputs and getting signals

Okay, so here we are in the session that we just created. Now I want to go ahead and send some signal and make sure that all my inputs are assigned, and get some levels in. I'm going to actually try and record my drum track first. I have hooked up my drum machine to my audio interface. So, I'm going to go ahead and get that signal sent, see if I've got some level, and try and record the drum track. But first, let me go ahead and clean up the window here a little bit for demonstration purposes. I'm going to also open our Mix window, and I'll actually slide this over here so I can see both of them at once.

Assigning inputs and getting signals

Okay, so here we are in the session that we just created. Now I want to go ahead and send some signal and make sure that all my inputs are assigned, and get some levels in. I'm going to actually try and record my drum track first. I have hooked up my drum machine to my audio interface. So, I'm going to go ahead and get that signal sent, see if I've got some level, and try and record the drum track. But first, let me go ahead and clean up the window here a little bit for demonstration purposes. I'm going to also open our Mix window, and I'll actually slide this over here so I can see both of them at once.

Sometimes, it's nice when you're setting levels to see the whole picture. I have my drum machine hooked up to input number 1. So I have to go in and assign that input to input number 1. The next thing I need to do to get signal is record-enable the track, or hit the magic red R, or in most software, it's going to some sort of red button. But red usually goes with recording, because it's kind of--they used to use red because it means a little bit of danger, because you don't want to record over something.

It used to untape it and then erase it at the same time as you were recording. So, record is red is danger, which is good, because you don't want to record over your best guitar take of all time by accidentally leaving the thing armed. So, before I arm it though, I'd like to fade down here so that if there is signal at that input, when I arm it, I'll immediately hear it. If it's a really loud signal, I don't want to get blown out by it. So, I always fade down first, hit the Record Enable button. So, now I'm going to go ahead and get the drum machine playing.

I'm going to go ahead and crank up the gain on input number 1 to get a little bit more signal. (music playing) There we go! I would probably try and turn it up, make it a little bit hotter than that. I want to try and get to the peak here. So, that's about all I can give it. I need to just give it a little bit more. (drums playing) That's good! We've got a peak in there.

That happens if you click out of that to see if you're still getting them. (drums playing) Yeah, that's pretty good! So, I'm pretty happy with that input and I'm going to go ahead and record this. So, I'm going to bring my cursor back to the beginning, and I'm going to hit the magic Record button. Notice because I have a track armed, I get a little red notification up here. Get ready to record, hit the Record button, and then play to start the action. Then I will hit Play on the old machine here. (drums playing) Yeah, that's old-school.

That's my way. It's just a little pattern I put together. That's pretty good! That should be plenty. All right, and we'll kill the source. All right! So, we've recorded the drums. So, we've got our track. It looks pretty good, labeled in there. So, that's it for basic recording. That's the story.

Next, we're going to look at overdubbing the voiceover track, and then doing a little punch-in.
