Claim 0:
1. A method for testing a bi-directional audio device under test (bi-directional audio DUT), the method comprising:
setting up the bi-directional audio DUT in a test room;
positioning one or more remote audio test devices (RATDs) within the test room, wherein each of the one or more RATDS is adapted to be—
positioned at the same or different height as the bi-directional audio DUT,
positioned at the same or different distance from the bi-directional audio DUT, and
positioned at the same or different angular displacement with respect to the bi-directional audio DUT;

selecting an audio signal test track on a host audio test device (HATD), wherein
the audio signal test track comprises one or more audio test signals;

transmitting the audio signal test track to the one or more RATDs from the host audio test device (HATD);
broadcasting the audio test signal by the RATD to the bi-directional audio DUT as an acoustic audio test signal; and
receiving the acoustic audio test signal from at at least one mic on the bi-directional audio DUT;
converting the received acoustic audio test signal to audio signal test data;
transmitting the audio signal test data to the HATD; and
calibrating one or more loudspeakers and one or more microphones that are part of one or more remote audio test devices (RATDs).
