Latest Patents

One of Bosun Xie's latest patents is a "Virtual playback method for surround-sound in multi-channel three-dimensional space." This invention discloses a virtual reproduction method for multichannel spatial surround sound in three-dimensional space. The method involves a sum and difference operation on multichannel spatial surround sound signals, processed with virtual reproduction signal processing functions. These signals are then fed to four actual loudspeakers arranged at specific angles to generate an auditory effect of spatial surround sound. This invention simplifies the number and arrangement of loudspeakers required for multichannel spatial surround sound reproduction, making it suitable for situations where multiple loudspeakers cannot be arranged, such as in a TV set.

Another significant patent is "Decorrelating audio signals for stereophonic and surround sound using coded and maximum-length-class sequences." This method includes generating a pseudorandom sequence and at least one reciprocal of that sequence, which is substantially decorrelated. The audio signal is convolved with this set of sequences to produce a corresponding number of output signals, which are then provided to a corresponding number of loudspeakers.
