Learn about setting the recording path and about setting sample rate and bit depth. Scott explains how to manipulate the settings to optimize latency and buffer size.
to get going recording live audio into Logic. First we'll need to go over some initial setup options to get the most out of your recordings. Once these are in place, you'll be busy recording tracks in no time. Here we have a new project we just started. Notice the name, which is untitled because I haven't saved it yet. and you don't just start recording audio files in random places on your computer. So let's go to file, save as, and we'll call this my recording. And I'll just go ahead and place this on the desktop and I'm going to include audio files. And that way anything I record will end up in the project folder. So click save and that'll set our recording path. Now, assuming our audio interface is properly set up, as we discussed in the connecting audio interfaces movie, we'll need to decide on three options for the audio files to record. We're going to decide on file type, sample rate, and bit depth. Let's first choose file type. So let's go up to preferences under recording. Now, these are global preferences under recording and here we can choose one of three file types, AIFF, WAV, or CAF. Now, the industry standard is WAV. These are all uncompressed file types. They don't have any differences sonically. They're just the way the file is written. I'm going to go ahead and choose WAV. Now, notice underneath that we have the option to make a 24-bit recording. Let's keep that on. I recommend it. It's really the best audio quality and it has If you were to uncheck this, you'd be recording record at the higher bit depth. To look at sample rate, that's actually in a different setup page. It's in the setup page that's attached to your project. So it's in the project settings. And you could go to the project settings from the file menu, file, project settings. Or they make it easy to pop over to the project settings So you can click here to get to the same spot. And here, under audio, is where we can choose the sample rate. So the project sample rate currently is 48 kilohertz, which is a good high-quality place to begin with. Now, some people like to record at higher sample rates, like 88.2 or 96. I think 48 kilohertz is a good baseline and it's a high sample rate to record at. A lot of people are working at 24 bits, 48 these days. So I'm going to recommend 48 for now. So now that we have file type, bit depth, and sample rate set, we can go ahead and see if we get input onto our track. So notice I made a guitar track. I loaded this up. So I chose clean guitar, brit and clean. And this guitar track, got again, close the library. Now, my guitar that I'm holding in my hand is actually connected to input one of an Apogee Duet. That's the interface I'm using. And the cool thing about Apogee Duet and Logic of the channel strip. This lets me decide what input type I'm using. So right now it's set to instrument but they have the opportunity to change it my guitar directly into the Apogee Duet. Now, keep in mind, if you're using these options here at the top. this trim button here. Again, may not be available if you're not using an Apogee. I can also set the input level on the Apogee Duet itself. So I spin this knob and notice my level is turning up I'm actually hearing the level come back a little bit later than when I'm playing it. This is called latency. So anytime you send audio through your computer, latency is caused by the round-trip time it takes to go from your guitar or whatever your input device is, maybe it's a microphone, into the computer system and then back through the computer system, back to your monitors or headphones. So computers have to use a memory buffer to stay ahead of what's coming in. latency if it's not set right. So let's go ahead and take a look at our buffer setting. So if I go up to Logic Pro once again, preferences, and here I'm going to go to audio. And notice the IO buffer size is set to 1,024 samples. Now, that's the highest buffer size. So that's going to give us the biggest buffer, which can allow for more software instruments and plugins, but the downside of this is my resulting latency, as you read below, is a whole 45.3 milliseconds. And that's why when I strum the chord I'm hearing it come back to my headphones So what you want to do here when you record is do a lower buffer size. So if I go down to, for example, 128, And now, when I strum my chord (guitar notes) I don't hear as much of a echo or a late signal coming back. And that's the low latency button in the transport window. Let's open the transport float window from the windows pull-down. Now here, as long as I'm showing the full transport floats, I'm going to go ahead and choose customs where I see everything. And I'm still not seeing it so I'm going to say customize control bar. And here I want to show low-latency mode. And when I say okay, I've got this little button Now again, let me just review that because when I opened the transport, it wasn't showing that. And if yours isn't showing it, there's a way to get it. customize control bar display. Now that I have that, I can also click here. In addition to going into the settings And that turns Logic into a mode where it's going to selectively bypass plugins and other processing to lower the latency so that when you record you get the least amount of latency so you hear or time delay. and editing, you may want to turn this off in addition to changing your buffer size here in the preferences. So now that we've got all that good stuff set up I can go ahead and start recording. What will the recording files be called when we record? before you hit record. So instead of something generic like guitar one, And that'll then name each of the regions I create, Scott's guitar one, Scott's guitar two, et cetera. So that's just a way to control what the files will be named before you start recording. Okay, we should be ready. Notice I added a drummer track because I prefer click track or metronome. It's a little more groovy, it's a little more fun to play to. So I put the rip pop drummer on here and I'm going to try to play something out of Manchester circa 1992. Here we go. I type the R button on my keyboard and that'll get us rolling. It'll give me a pre-roll and then I'm off and running. (upbeat music) And when I hit stop, you can see the region was named after the track name, Scott's guitar oh one. Congratulations. We've now made our first audio recording. And now you know all the required steps to set up Logic to record audio. each time you record to ensure you got the right sample rate and bit depth and that your audio is going to the correct place.
