Latest Patents

Hoffman's latest patents include advancements in digital audio signal coding using a CELP coder and a transform coder. One patent describes an apparatus for digitally encoding an input audio signal for storage or transmission. This invention measures a distinguishing parameter from the input signal to determine whether it contains an audio signal of a first type or a second type. The system employs first and second coders to digitally encode the input signal using different coding methods. A switching arrangement directs the generation of an output signal by encoding the input signal according to the type of audio signal present. This method allows for adaptive switching between the transform audio coder and the CELP coder, leveraging the strengths of both for improved audio quality.

Another patent focuses on an apparatus for digitally encoding an input audio signal, which includes a pitch detector to determine the dominant time-domain periodicity in the input signal. This invention generates a prediction signal based on the detected periodicity and utilizes discrete frequency domain transform generators to create frequency domain representations of both the input and prediction signals. The system subtracts the prediction signal's representation from that of the input signal to generate an error signal, which is then used to produce an output signal.
