In this article, we'll look at how to change the buffer size within Pro Tools Artist

You may wish to change your buffer size for two reasons:

1. Your roundtrip latency is too high during recording, so you may wish to reduce your buffer size.
2. Your audio is glitching, you may wish to increase your buffer size to relieve strain on the CPU and achieve clean audio again.

To change the buffer size in Pro Tools Artist:

1. Set your interface as the default audio device within the Playback Engine. When you first install and open Pro Tools | Artist this will automatically open for you.
2. Click the 'Setup' menu at the top of your screen -> Playback Engine.

The Pro Tools Artist Playback Engine will allow you to choose several Buffer sizes, the lower the buffer size the lower the latency. Select the option that best suits your current usage and select 'OK'. You might want a lower buffer when recording however a higher buffer when mixing and editing.
