Audio Testing Mode
Screen Testing Mode
WALT is designed to measure the latency of physical sensors
and outputs on phones and computers. It can currently perform the following measurements:
tap latency, drag latency (scroll), screen draw latency, audio output/microphone
latencies, and MIDI input/output latencies.
DISCLAIMER: This is not an official Google product.
A WALT device is required to run the latency tests. For more information, visit github.com/google/walt
