Mr. Yudai Iga is sitting at left-hand side and translating English demonstration to Japanese. Mr. Dan Dugan is located at the inner part of the room.
Dan Dugan demonstrated a adaptive threshold automatic microphone mixer. He outlined his development process, explained the math, and demonstrated the performance of his popular algorithm using eight microphones. Listener's interests and questions were as follows: How to set the threshold parameter for each channel? How long is the attack time and release time of the gain control? and the algorithm for automixing of musical sounds, especially singing voices.
