I've been initiating my new research topic personal sound zone (also called personal audio, multi-zone sound reproduction, etc), which is a branch of spatial sound reproduction.
The consistency of the amplitude response and phase response (related with the latency consistency) between the loudspeaker-array elements are important for accurately controlling the sound fields in the space. Thus, I'm wondering if there is any standard approach to do the calibration between the array elements.
As we know, the calibration of a microphone array is straightforward. This is because the mics receive the signals, and we can easily evaluate the channel consistency with the received signals. While in order to calibrate a loudspeaker array, I assume, one has to consider the overall response of loudspeaker-room-mic. Is that right?
I'm new in this study. I don't know if there is any stand approach or any open source tool box for this. Will be appreciate if anyone can give some advice. Thank you.
