scope:

The present document describes a methodology for recording and reproducing different room characteristics and realistic reverberation under conditions that are well-defined and tailored for a calibrated setup in a lab environment. The individual aspects of the description are:

• Measurement of room impulse responses.

• Processing of test signals.

• Loudspeaker setup, calibration and equalization.

The methodology is fundamentally designed for use without access to internals of the Device Under Test (DUT), e.g. the exact positions and orientations of the device's microphones or the unprocessed microphone signals. The methodology is intended to be used for performance evaluation of all types of devices where the room characteristics may impact the performance.
