Title: The Innovative Contributions of Carl Grundstrom
Introduction
Carl Grundstrom is a notable inventor based in Sandy, UT (US). He has made significant contributions to the field of audio signal processing, holding 2 patents that showcase his expertise and innovative thinking. His work focuses on enhancing audio clarity and improving the quality of sound through advanced techniques.
Latest Patents
One of Grundstrom's latest patents is titled "Multi-aural MMSE analysis techniques for clarifying audio signals." This invention involves techniques for processing audio signals, which include removing noise and clarifying audio prior to output. The methods utilize minimum mean squared error (MMSE) analyses on audio signals received from a primary microphone and at least one reference microphone. Additionally, confidence intervals may be assigned to different frequency bands, indicating the likelihood that each band contains targeted audio.
Another significant patent is the "Adaptive interchannel discriminative rescaling filter." This method adjusts the degree of filtering applied to an audio signal by modeling a probability density function (PDF) of fast Fourier transform (FFT) coefficients from both primary and reference channels. The technique emphasizes the primary channel when its spectral magnitude is stronger than that of the reference channel, ensuring optimal audio quality.
