6 Tips To Optimize The Performance Of Ableton Live

Making music on a computer can sometimes present ugly problems; Laggy Audio, CPU spikes, the list could go on forever. Find out how to prevent these.

It’s not like the old days. Making music on a computer has it’s own set of problems we have to deal with. Laggy Audio, CPU spikes, the list could go on forever.

Usually these are a result of not getting the maximum performance out of Ableton Live. Here are some tips:



1. Enable Multicore Support

Go under Options>Preferences, locate the CPU tab and make sure your “Multicore/Multiprocessor” tab is selected. This allows Live to distribute the CPU load amongst multiple cores and CPUs (if your computer supports it).

To find out if your computer supports multiple cores and processors in a PC, you can right click on My Computer>Properties, and it will tell you your CPU type.

For Mac users, most modern Macs and MacBooks have multicore processor built it.

2. Freeze Tracks

Freezing tracks can save you a lot of CPU power. I work with Native Instruments Guitar Rig on some tracks, and this thing is a CPU consumption beast. Keep your CPU meter down by simply right clicking the desired track and selecting “Freeze”.

3. Stick To The 44.1kHz Sample Rate

Disclaimer: I am not an Audio Engineer. I am just basing this on my humble personal experiences.

It is of this writer’s opinion that if you are mixing and mastering your own music, anything above 44.1kHz is a waste of time. Unless you are have a mastering engineer’s set up, keep it at 44.1kHz; it saves processing power.

A consumer level CD-R burned out of iTunes will render at 16 bits and 44.1kHz. However, it is a good idea to have your bit rate set to 24 in Ableton because this will give you more dynamic headroom while mixing/mastering the track.

Final thought: A bad song (poorly mixed, mastered, etc) exported out at 96kHz will not make it noticeably better.

4. Use Live’s Buffer Settings

Here is a general rule of thumb: Poor CPU performance (stuttering audio) means you should raise the buffer level (512 to 1,024 samples ought to do). The trade off? Higher latency (the lag between playing a sound and hearing it).

At lower buffer levels your latency should be nearly gone, however, you will experience higher CPU loads, as well as audio dropouts.

Final thought: Find a happy medium where your latency is tolerable, and you are not having constant CPU spikes. (I have mine set at 256).

5. Use Sends For Effects

Some people get into the habit of dropping multiple effects that have similar settings on each of their tracks. To save on CPU power, use sends!

Drop a single effect onto one of Ableton’s Send tracks, and you can instantly send the signal of this effect by simply turning up the send knob on individual tracks. Make sure you have the wet knob turned up to 100% on the effect.

6. Get Rid Of Unnecessary Applications

For the PC it’s Ctrl+Alt+Del to enter the task manager, for the Mac it’s Cmd+Option+Esc. Whichever OS you’re running use these application managers to kill any un used programs in the background.

As an extra word of advice to mac users, be sure to turn off your airport when running Ableton.


Hopefully these tricks will help you to get the most out of your Ableton Live experience. I am sure there could be a few I am missing, if anyone would like to share, please comment below!

  1. The airport thing is a really good call. Don’t know why this makes a difference(as in, it shouldn’t) but it does.

  2. i some tricks too…

    Turn off from your audio loops the
    Hi-Q and Fade buttons…

    also do a collect and save after saving your sessions… this goin to make easier for Live to find the samples on your hard disk and reducing cpu spikes…

  3. This is great, thanks!

    i have also found that keeping your screen as dimm as you can stand while working on a laptop helps LOADS! At least it does for me.. especially on long seshes, keeps the fans from running so hard.

    Hope it helps some one else!

  4. I also click off the warp functionality when it is unnecessary…. its surprising how much it drops cpu load

  5. The reason why you want to have samples at 96khz is because fx will work better when applied.
    If you are at the last stage and you just want to play a recorded sample with no fx 44.100 is ok.
    It all depends by the fx.

  6. “turn off your airport when running Ableton”

    What about people who use WiFi connection for controllers like Limur or TouchOSC , TouchAble ? If you use MAC should be no problem, if you use PC go for MAC as soon as you can and forget PC. This is no sarcasm here, this is my advice.
