Join Joe Godfrey for an in-depth discussion in this video Setting up audio interfaces, part of Logic Pro 8 Essential Training.
In this movie we are going to talk about setting up audio interfaces, getting digital audio into Logic. There are lots of ways to get digital audio into Logic. If you are transitioning from GarageBand, you may have one of those devices you buy at the Apple store. You plug it into your guitar. It goes into the line input of your laptop or your Macintosh. And Logic will accommodate that and it will accommodate everything through rackmount FireWire interfaces, all the way up to the fanciest TDM systems. So let's look at some options for audio interfaces.
I will open the Guitar Tones and again, I have the option of saving this project, which I am not going to do. I will go to Logic Pro > Preferences and Audio and I get this window. Now, there are lots of different options here for Preferences. We will explore them as we move through different movies. The one we are interested in now is Audio. So we will go to Devices and we have Core Audio, DAE, and Direct TDM. Let's go backwards. TDM is Time Delay Multiplexing, and that's what we use if we have a giant Pro Tools TDM system hooked up to the Mac.
DAE Digidesign Audio Engine, maybe you're transitioning from Pro Tools, you have an Mbox, an M-Audio interface, something in the Digidesign family. This would be your choice here. We are going to use Core Audio. That's Apple's FireWire driven interface. So when we say Enabled and Apply Changes, so we applied the changes, and now Logic has a place to send this audio. You will notice that our plug-ins came back. They are not grayed out, they don't have a black line through them anymore, so now Logic has a place to send them.
Because we are not using the Build-in Line Output and Input here, we are going to switch to the MOTU 8pre. That's our interface. It's a FireWire driven interface, and apply those changes. The Core Audio window pops up to tell us it's doing it and now we have chosen that interface. All right, so once I have applied these changes, I have some other choices to make here. This has to do with how the Macintosh processes the digital audio off your hard drive. I will bet you that these default settings would work just fine for your computer if it's a relatively fresh computer.
If you are working on the fastest, newest Mac you got yesterday, you may want to kick the buffer size up. It will process a little faster. If you are working on an older system, you may need to kick this down. You will know because Logic will not be pulling your audio off the hard drive. It will stutter and pause and this is where you will go to make changes if you need them. But try the default settings and see if they work. If you want to record everything you do in 24-Bit Recording, this is where you make that choice. Down here, there are some Buffer Ranges and things, and these are choices you make based on the CPU power that you are dealing with.
So, try the default settings. If you are having issues, this is where you will go to make those changes. One really important thing we want to verify is that Logic and our audio interface are speaking the same language as far as sample rate. So where we go to do that is let's pop over to our MOTU Audio Setup and there is the panel for that. And this is seeing a sample rate of 441. So we want to jump back into Logic for a second, look at our Project Settings for Audio.
This brings up another panel altogether. We have a lot of choices to make here, which we'll explore later on, but right now we want to look at Audio. And our Sample Rate is 441. We have all these other choices to make too. Your audio interface may determine how far down this list you can go. The way we are wired with FireWire, we can use these two. If we are using a light pipe, we can use these two. So, depending on which interface you have and how you have it hooked up, that's the sample rate you will choose for your project.
What I want to verify is that Logic and our audio interface are talking to one another. So I am going to pull up my MOTU Audio Setup again and change my Sample Rate from 44 to 48. And there is it over in the MOTU Audio Setup, changed to 48. I am going to change it back to 441, and the MOTU Audio Setup found it at 441. So I know that this audio interface and Logic are speaking the same language now. That makes me happy.
Beyond sample rates, there is one other aspect of digital audio that we need to talk about and that's in the next movie, Word Clock.
