This bit walks through Ableton Live's Audio preferences tab, breaking down the four sections that control how Live talks to your audio interface. It covers driver and interface selection, input and output routing, sample rate, and latency, giving a clear map of where each setting lives before you go tweaking things.
Sample rate and latency get specific attention since they directly affect recording quality and the responsiveness of your session. The higher your sample rate, the more demanding it is on your system, while lower latency settings make playing and recording feel more immediate but push your CPU harder.
The tab also includes a built-in CPU load test, which simulates processing strain to check whether your chosen latency setting will cause clicks, pops, or dropouts during real use. Running this test before a session helps you find a stable balance between responsiveness and performance, rather than discovering audio artifacts mid-take.
