Abstract

In this lesson, you'll see how to use Live for recording live instruments or voice. You'll learn about routing, monitoring and multitrack recording, and you may even figure out how to play incredibly fast guitar solos.

Recording Audio

[Note: this lesson and an accompanying Live Set are also installed with Ableton Live and are viewable within the program itself. These lessons can be accessed from Live's Help View. You can read the lesson on the web or from within Live, but we recommend loading the Live Set that accompanies it as you follow along.]

Before we begin, take a look at Live's Info View:

Info View

Info View


The Info View resides in the lower-left corner of the Live application window. It's a very handy resource that will tell you about almost anything that you point your mouse over. Like many other views in Live, it can be shown or hidden as needed just by clicking the triangular unfold button near its lower-left corner.

The Arrangement

In this lesson we'll be working in Live's Arrangement View, which is currently shown in the upper-middle section of the application window.

Arrangement Overview

Arrangement Overview

The Arrangement can be used just like a tape recorder - sounds can be recorded into it freely. Your recordings can be played back at any time, starting from any point. When you're happy with something that you've created, it can be exported from Live so that you can burn it onto a CD or DVD.

Let's make some more room for the Arrangement by folding away the Browser at the upper-left side of the screen. It also has an unfold button, just like the Info View.

The Arrangement Mixer

This Live Set contains one empty audio track, which is currently titled "1 Audio." In a moment, we'll prepare this track for recording.

The right side of the Arrangement View belongs to Live's mixer.

The mixer has many features which help you build and refine the sound of your Live Set. We don't usually need to access all of them at once, so the mixer is divided into sections which can be shown or hidden as needed. In this lesson, we're only interested in the In/Out and Mixer sections, so go ahead and click on the Show/Hide selectors in the lower-right corner of the Arrangement View until only IO and M are enabled:

Input Routing

We use the In/Out section of Live's mixer to tell each track where to look for incoming audio signals (inputs), and where to send its audio signals to (outputs):

Arrangement I/O Section

The pair of input choosers in the In/Out section show that our track is receiving audio from external channels 1 and 2. This is probably the computer's standard audio input (a built-in microphone or Line In jack).

Input 1 and 2

Input 1 and 2



The upper input chooser allows you to select from among various input sources: external inputs ('Ext. In'), other tracks, or signals from ReWire applications.

The lower input chooser is where you can select from different input channels, which is common when working with multichannel audio interfaces. 

Arming an Audio Track

Before recording can begin, we have to arm our audio track by clicking on its Arm button, shown below. This prepares Live for the recording process.

Note: If you hear loud feedback when you arm the track, click the arm button once again to silence it, then read on to find out what's going on.

Track 1 Armed

Track 1 Armed

Once the track is armed, you'll see that its level meter shows the signal level of the track's input. This represents the volume of the sound which will be recorded.

Input Meter

If no signal is indicated in the meter, first lower the volume of your speakers or headphones so that any sudden volume changes don't damage your ears or equipment. Then, verify that you've selected an input channel that has an instrument or microphone connected to it. Once you've identified and fixed the problem, remember to return the volume to a reasonable level.

Monitoring

We usually want to hear what we are recording, and monitoring determines how we listen to the signals at our chosen track inputs.

These three switches in the In/Out section allow you to set the monitoring behavior of each audio and MIDI track individually:

Monitoring Section

Monitoring Section

  • Choose Off if you are monitoring directly, that is, through the audio interface or through an external mixing board - or through the open air.
  • Choose Auto to monitor the input signal through Live. If you hear an echo or get feedback, you have a direct monitoring setup. Either set the track's monitoring switch to Off, or deactivate your audio interface's direct monitoring option.

When monitoring through any software, there will always be some amount of delay or latency between your actions and the audible result.

Preparing to Record

Now that audio signals are showing up in Live and we have a way to monitor them, we're ready to record a take into the Arrangement. First, verify that the audio track is still armed:

Track 1 Armed

Now press the Control Bar's Stop button twice. This resets the Arrangement to the beginning, at position 1.1.1.

Next, press the adjacent Global Record button. (This is probably familiar to those of you who have used multitrack tape machines: Individual tracks can be armed for recording, then the Global Record button enables recording for those armed tracks.)

Finally, press the Control Bar's Play button (or hit the space bar on your computer's keyboard) to begin recording.

Now's the time to make some noise!

Recording and Playback

As recording progresses, you'll see a new audio clip being created in the track.

To stop recording, press the Stop button in the Control Bar, or hit the space bar again.

Now, press the Stop button one more time (resetting the Arrangement to 1.1.1), and listen to your recording by pressing the Play button.

Navigating the Arrangement

If you recorded for long enough, the Arrangement may have started to scroll horizontally. To scroll the view backward or forward, or to zoom in or out, grab the beat-time ruler along the top of the Arrangement with the mouse:

  • Vertical mouse movements zoom in and out;
  • Horizontal movements scroll left and right.

Timeline Recording

Playback and recording can start from any point in the song. You can set an insert mark by clicking anywhere in the Arrangement View (except on a clip's title bar), and the song will start playing from that point next time.

If you're not satisfied with what you've recorded, don't fret! A quick press of [Ctrl-Z] on Windows or [CMD-Z] on a Mac is all that's needed to undo a take, and be ready to try again.

The Metronome

It's important to record in sync to ensure that everything will later play in sync.

The easiest way to record in sync is to use Live's built-in metronome, which is activated via its Control Bar switch. You'll find it in the upper-left corner of the application window:

Metronome Switch

Metronome Switch



The metronome ticks at the current tempo while Live is playing. Enable the metronome, then press the space bar to start playback. You can adjust the metronome's volume using the Master track's Cue Volume control, shown below. Press the space bar again to stop.

Cue Volume

Note: If your recordings sound delayed with respect to the metronome, you probably need to set up latency compensation. Latency compensation is a trick that the program employs in a direct monitoring scenario to compensate for delays incurred by the audio interface and its drivers.

Tempo Tricks, Count-in and Tapping

The tempo of your Live Set can be changed at any time: before, after and even during recording. You could, for instance, cheat a bit by lowering the tempo while you record a complicated guitar solo, then bring it up again when you're done.

Another helpful technique is the use of a count-in when recording. This gives you a chance to prepare for a take before the recording actually begins. To set up this behavior, open the Preferences via the Options menu (PC) or Live menu (Mac), and choose the Record/Warp/Launch tab. When the Count-In preference is set to any value other than "None," Live will not begin recording until the count-in is complete.

Alternatively, you can have Live follow your counting instead of the other way around. With a 4/4 time signature, it takes four clicks on the TAP button before Live starts playing (or recording).

Multitrack Recording

Press [Ctrl + T] on Windows or [CMD-T] on a Mac to create a new audio track for your next take. Unfold the new track by clicking the unfold button in its title bar:

New Track Arm

Remember to activate the new track's Arm button, otherwise you'll end up recording into track 1 again. By default, arming one track unarms all others. You can, however, independently arm and unarm tracks by [Ctrl + click] on Windows or [CMD + click] on Mac their Arm buttons. This way you can set up any number of tracks to record simultaneously.

Obviously, this wouldn't make much sense unless you had set the tracks up to receive different input signals (from each band member, for instance). In our example above, we've altered our input selections so that track 1 records input 1 as mono, and track 2 records input 2 as mono.

Go ahead and record a new take, using the metronome as a tempo guide. Remember to press the Stop button or hit the Space Bar when you've finished.

Doing it Again (and Again...)

If you'd like to redo only a certain part of a take, you can set up punch points: Drag the left and right edges of the loop brace to define the in and out points...

... then activate the Punch-In and Punch-Out switches in the Control Bar.

Punch Switches

Punch Switches



  • When the Punch-In switch is on, Live will protect the material lying before the loop brace;
  • When the Punch-Out switch is on, Live will protect the material following the loop brace.

The loop brace can also be used to define a section of the Arrangement to be looped: You can set up a loop, record as many takes as you like without interruption, and Live will retain the audio recorded during each pass. You can later "unroll" the loop recording using the Undo function. The loop is engaged by using its Control Bar switch:
