Digital Audio and Latency

Digital audio workstations process sound in chunks called buffers. The buffer size determines the trade-off between latency and CPU load. Smaller buffers mean lower latency but higher CPU demand, while larger buffers give more processing headroom at the cost of audible delay.

The buffer latency calculator computes input, output and round-trip latency from your buffer size and sample rate, including driver overhead and plugin processing delays. It tells you whether your current settings are suitable for tracking with live monitoring.

As a general guideline, musicians can comfortably perform with round-trip latency below 10ms. Above 20ms, delay becomes noticeable and can affect timing. For mixing-only sessions where live monitoring is not needed, larger buffers (512 or 1024 samples) free up CPU for more plugins.
