Does TrueRTAs Quick Sweep have a gating function?
There is gating but it is sufficiently wide that it does not exclude room reflections on the acquired sweep. Because of the wide gate, room reflections will influence measurements when testing indoors. For this reason I recommend performing your most critical measurements outside in the open whenever possible. This is really the only way to remove the effect of the room from the measurements. Gated in-room measurements therefore are not particularly useful in the bass range…where the worst problems tend to occur. Measurements made outdoors in the open using Quick Sweep can be truly anechoic while retaining full low frequency resolution. Indoors Quick Sweep shows you the combination of the speaker response and the room influence…as you normally hear the combination. Taking the difference between the ground plane (half-space) response and the in-room response reveals the effect of the room.
