ETC measures room decay time graphically, by showing the decay of a pulse over time. Typically, you will make an impulse sound by clapping your hands, popping a balloon, or even snapping your fingers. The graph will show the decay of this signal over time, and from this, the RT60 time can be computed.
This shows a typical ETC measurement, made by simply snapping fingers in a small office, using External Trigger mode (see below).
You can see the initial peak sound, and the decay of the sound over time. A-Weighting was used to remove low frequencies (and very high ones) from the test. We used a 400ms time window to capture the full decay of the impulse.
Using a two-finger swipe gesture to move the cursors over the linear portion of the decay curve, the app calculates the equivalent RT60 time of the decay. This is shown on the purple cursor, and with the green decay line.
