Huan Zhou is a prominent inventor based in Singapore, known for his significant contributions to audio technology. With a total of 12 patents to his name, Zhou has made remarkable advancements in bandwidth extension methods that enhance audio quality while reducing computational demands.

Latest Patents

His latest patents include a bandwidth extension method, bandwidth extension apparatus, program, integrated circuit, and audio decoding apparatus. These innovations aim to provide a bandwidth extension method that allows for a reduction in computation amount and suppression of quality deterioration in the bandwidth being extended. The method involves transforming a low-frequency bandwidth signal into a QMF domain to generate a first low-frequency QMF spectrum. Pitch-shifted signals are created by applying different shifting factors to the low-frequency bandwidth signal. A high-frequency QMF spectrum is then generated by time-stretching the pitch-shifted signals in the QMF domain. The high-frequency QMF spectrum is modified and combined with the first low-frequency QMF spectrum to achieve the desired audio quality.
