Latency

Latency is defined as the time it takes for your input signal to pass through your audio software and appear at the outputs. Smaller buffer sizes result in lower latency, but may not function well with slower systems.This drop-down menu selects the buffer size Transit USB uses to handle digital audio streaming.

The default Latency setting is “Medium.” This setting may adequately serve your purposes, but if you wish to, you can experiment with lower settings. If you experience stuttering or crackling in your audio playback, try using a higher latency setting.
