This paper proposes a novel multichannel audio signal compression method based on tensor decomposition. The multichannel audio tensor space is established with three factors (channel, time, and frequency) and is decomposed into the core tensor and three factor matrices based on tucker model. Only the truncated core tensor is transmitted to the decoder which(More)
Head-related transfer functions (HRTFs) or its time-domain counterpart, head-related impulse responses (HRIRs) play a crucial role in 3-D audio rendering. The HRIRs with a couple of hundred-sample lengths result in the high computation cost for the real-time 3-D audio applications especially when multiple sound sources are rendered simultaneously.
