Title: Hiroshi Iriyama: Innovator in Multi-Channel Sound Technology
Introduction
Hiroshi Iriyama is a notable inventor based in Shizuoka, Japan. He has made significant contributions to the field of sound technology, particularly in multi-channel echo cancellation and sound transfer methods. With a total of 4 patents to his name, Iriyama's work has advanced the way stereo sound is processed and reproduced.
Latest Patents
Iriyama's latest patents include innovative technologies such as the multi-channel echo cancel method, multi-channel sound transfer method, stereo echo canceller, and stereo sound transfer apparatus. His work on the transfer function calculation apparatus allows stereo sound signals to be reproduced directly from loudspeakers (SP(L), SP(R)). By utilizing a sum signal and a difference signal of the stereo sound signals as a reference, he performs cross spectrum calculations with microphone-collected sound signals. This process enables the calculation of transfer functions for four sound transfer systems between the loudspeakers and microphones (MC(L), MC(R)). The resulting transfer functions undergo inverse Fourier transform to derive impulse responses, which are then used to create echo cancel signals, effectively addressing the challenges associated with indefinite coefficients in multi-channel sound signal echo cancellation.
Career Highlights
Iriyama's career is marked by his dedication to advancing audio technology. His innovative approaches have not only led to multiple patents but have also positioned him as a key figure in the industry.
