Latest Patents

Yuan-An Kao holds a patent for "High-efficiency algorithms using minimum mean absolute error splicing." This patent discloses a method for modifying parameters of audio signals by dividing a digital signal, which is converted from an original analog signal, into sound frames. The method involves modifying the pitch and playing rate of the digital signal within a frame, followed by the successive splicing of the last modified frame with the first non-modified frame. The process calculates the mean absolute error to define the best splicing point, aiming to produce minimal or no audible noise. This allows various sections of sound signals to be spliced together effectively, achieving desired pitch and playing rate modifications. An apparatus is also described for implementing this method, which includes input and output amplifiers, low pass filters, analog-to-digital and digital-to-analog converters, and a pitch shifting processor.
