摘要

This dissertation presents a prototype system to treat the problems of conducting remote collaborative recording without musicians traveling to be local to each other. Two main issues are explored and studied: realtime loudspeaker-microphone feedback control, and the removal of far-end reference signal from recorded audio in the post production. The design of this system includes a smart system integration of existing techniques. Innovative algorithm designs on some other components are also presented. This system is simulated with Matlab and Pd for off-line and realtime analyses, respectively. The results show that it works robustly as an echo canceller against loudspeaker-microphone feedback; it also performs competently in demixing the recorded audio and removing unwanted components generated from the far-end reference speaker.
