We propose a new design criterion for subband adaptive filters (SAFs). The proposed multiple-constraint optimization criterion is based on the principle of minimal disturbance, where the multiple constraints are imposed on the updated subband filter outputs. Compared to the classical fullband least-mean-square (LMS) algorithm, the subband adaptive filtering(More)
Nowadays, portable devices demand small-sized and low-end loudspeaker, however, the physical acoustic bass (or low-frequency) reproduction is usually poor. Bass enhancement by equalization is not feasible, and may even overload or damage the loudspeaker. Bass enhancement for such low-end loudspeaker can be psychoacoustically accomplished by exploiting the(More)
In this paper, we present design and real-time implementation of a single-channel adaptive feedback active noise control (AFANC) headset for audio and communication applications. Several important design and implementation considerations, such as the ideal position of error microphone, training signal used, selection of adaptive algorithms and structures(More)
Audio signals for moving pictures and video games are often linear combinations of primary and ambient components. In spatial audio analysis-synthesis, these mixed signals are usually decomposed into primary and ambient components to facilitate flexible spatial rendering and enhancement. Existing approaches such as principal component analysis (PCA) and(More)
