UPMIXING SYSTEMS AND METHODS FOR EXTENDING STEREO SIGNALS TO MULTI-CHANNEL FORMATS
This abstract first appeared for US patent application 20250106577 titled 'UPMIXING SYSTEMS AND METHODS FOR EXTENDING STEREO SIGNALS TO MULTI-CHANNEL FORMATS
Original Abstract Submitted
the present disclosure describes systems and methods for audio signal processing, and more specifically, techniques for automatically generating surround sound by extending stereo signals including a left and right channel to multi-channel formats in an unsupervised and content-independent or content-agnostic manner. in operation, a computing device may receive a stereo audio input signal containing two channels from a sound source. the computing device may transform the stereo audio input signal into an upmixed multi-channel time domain audio signal to create an immersive surround sound listening experience by wrapping the original stereo field to a higher number of speakers in the frequency domain. based at least on the continuous mapping and the panning coefficient, the computing device may generate the upmixed multi-channel time domain audio signal.
