With a total of seven patents to his name, Zotkin has made significant strides in enhancing auditory experiences through innovative methods and systems.

Latest Patents

Zotkin's latest patents include an audio signal processor and generator, which features a spatial-audio recording system. This system comprises a plurality of microphones and a computing device that determines a plane-wave transfer function based on the device's physical shape. The computing device expands this function to generate a spherical-harmonics transfer function, allowing for the retrieval of signals captured by the microphones. It then determines spherical-harmonics coefficients for an audio signal and generates the audio signal based on these coefficients.

Another significant patent is focused on the sparse decomposition of head-related impulse responses with applications to spatial audio rendering. This application outlines methods for signal processing and spatial audio synthesis. It involves generating an impression of auditory virtual reality by processing an auditory signal to impart spatial characteristics through convolution with head-related impulse responses. The method reduces computational complexity by allowing the first convolution to be pre-computed while performing the second convolution in real-time.
