How can i save CPU power?

I have a pretty large set and Live CPU meter peaks often while causing the audio to distort.

Is there something i can tweak in Live or my computer to make it run faster?

I tried raising the buffer size but i can't go above 128, because on the live guitar input...

Something like a preferences setting that positively affects the CPU load Live creates?

    • lower the sample rate
    • make sure you have sufficient free memory
    • make sure multi-processing is activated 
    • make use of the "Freeze" function
    • think of resampling tracks with devices to eliminate processing power of the devices
    • enlarge your buffer size to reduce CPU load
    • check if other programs run besides Live and close them if you don't need them

    In addition to all those tips mentioned before, I suggest you to go through each synth and effect you have in your project and turn any unnecessary oscillators, envelopes, LFOs and FX off. For example, if you use EQ-8, turn off any unused bands (in addition, you might want to right-click on the titlebar of EQ-8 and uncheck "Hi-Quality"). If you use Live's reverb, try turning of Chorus. If you use Simpler, reduce the amount of voices in each instance to the amount really necessary. And so on...

    Another simple but often overlooked tip to reduce CPU is to ensure that you have your unused audio inputs and outputs on your soundcard disabled by clicking on both the "input config" and "output config" buttons in the Audio tab of the preferences.

    Another thing is you may not want to increase your buffer during the recording phase but when mixing down put your buffer up.

    I tend to use this technique a lot to increase the available CPU power for final mixdown.

    Put CPU-heavy effects into Return tracks so that you can process many tracks with the same effect.

    Reverb can be a very CPU intensive effect, so rather than putting it on multiple tracks, put it on Return track A, then increase the Send A level on the tracks you want reverbed to route them to Return A.

    What you can also do if you are playing live is to render tracks with effects (Compressor, Delay, Reverb, etc.) that you don't want to manipulate during a live situation. If the sounds are fine as they are just render them and import them like this to avoid unnecessary computation.

    Consolidate any complex pro clips you would have in a set.

    When time comes to bring your music into live situations, no way to worry about cpu.

    consolidate your clips to beats or repitch mode will relief process, rendering midi to audio is also the best way to be cool while playing on stage

    I you use Windows XP and a laptop CPU with SpeedStep (Intel) support, you have a throttle-like control over processor speed, it can be "Adaptive", "Constant" or "Maximum". "Adaptive" means "save battery, maximize performance" at the same time, which is not good, because audio needs constant timing. You should either go for "Constant" or "Maximum" to remove unnecessary processor throttling while playing complex sets. See the "powercfg" command-line tool. Usually, the command is "powercfg /change "Power Scheme Name" /processor-throttle-ac (or dc) ADAPTIVE/CONSTANT/MAXIMUM"

    The sample rate you use will have a significant effect on the CPU usage. Often I work at 96k but when it gets to be too much for my system I go down to 48k, which can sound a bit different depending on what you're doing, but it definitely reduces CPU usage.

    Make sure you turn off your airport!

    Disable anti-virus software!

    Use less third-party effects and more the Ableton "on-board" effects!

    Regularly repair your permissions!

    Keep your sample libraries on external hard-drives so that your internal drive is only used for applications!

    "Keep your sample libraries on external hard-drives so that your internal drive is only used for applications!"

    Is that really useful? I mean, does loading files from several different sources not tends to be slower than from one single source? I do use my external hard drive for audio samples but I wasn't so sure about the efficiency, compared to all in 1 hdd method. I personally didn't notice a lotta changes, but I'm interested in this question if someone got some sure infos on it.

    Thanks :)

    Use Activity Monitor (mac) to see what background applications are taking up CPU speed. I had a 'Chrome helper' app running in the background even though Chrome wasn't running, which was using over 70% of CPU! I ended that process and got that speed back.

    i've done everything you are suggesting. but my cpu load is still about 50% with audio glitches even with 5 tracks...

    Macbook Pro 8GB, Mountain Lion, Ableton 9

    Hi eliawk,

    Please contact support@ableton.com with a status report, so we can have a look into things for you.

    You can create a status report by going to help -> get support in Live 9.

    Best,

    I was working on a 20 track live set and froze and flattened all of my tracks from midi to save cpu but my live meter still reads 60% which is pretty much what it was before - this doesn't seem right? Does it?
