Live's CPU load spikes to high values, resulting in dropouts, crackles or glitches of the software.
There can be different reasons for this to happen, and this article will provide a step by step checklist to reduce the CPU load of Live.
- Lower the Sample Rate in Live's Preferences → Audio. Try setting it to a value of 44100 or 48000 Hz, which will reduce CPU load drastically if you have used a higher value before. Ideally, you should pick the correct setting before starting a new project, rather than changing it while working on an existing one.
- Increase the Buffer Size in Live's Preferences → Audio, ideally to a value by the power of 2, like 128, 256, 512 or 1024. Keep in mind that the higher this value is, the higher will audio latency be.
- Check the harddrive of your machine if you have sufficient space available. As a rule of thumb, you should always have 10% of your hard drive's capacity available as free space.
- Make sure the Multicore/Multiprocessor support is activated in Live's Preferences → CPU.
- Make use of the Freeze function for tracks containing CPU-heavy devices. To freeze a track, right-click it and choose "Freeze Track".
- You can also resample tracks containing CPU-heavy devices. Please refer to Live's Manual Chapter 14.5. Resampling for further reference.
- Check the Activity Monitor (Mac) by pressing [cmd][space] and typing "activity monitor" into Spotlight, or Task Manager (Win) by right-clicking your task bar to see if other applications might be consuming much CPU and/or RAM on your machine.
In this article you can learn why Live's CPU Load meter might display different values than Activity Monitor or the Task Manager.
- In Live's Preferences → Audio → "Input Config" and "Output Config" disable inputs and outputs from your audio interface if you are not actively using them.
- Put CPU-heavy effects into Return tracks so that you can process more than one track with the same effect.
- Use the Warping algorithm Complex and Complex Pro sparingly, and eventually consolidate those clips.
- Reduce the polyphony of your Sampler and/or Synthesizer instruments.
Some Live devices come with a Spread parameter (e.g. Utility, Corpus, Operator): please use this sparingly.
- Set the Reverb to "Eco" mode.
- De-activate the Hi-Q switch on audio clips. This setting improves the Sample Rate conversion when transposing audio files, at the cost of higher CPU drain.
- De-activate your Wi-Fi.
