Title: Innovations of Thomas Lee Worrall
Introduction
Thomas Lee Worrall is an accomplished inventor based in Boulder, CO (US). He is known for his significant contributions to audio technology, particularly in the field of dynamic range compression. His innovative approach has led to the development of a unique audio compressor that enhances sound quality without introducing undesirable artifacts.
Latest Patents
Worrall holds a patent for a "Continuous frequency dynamic range audio compressor." This invention features an improved multiband audio compressor that performs well for both wideband and narrowband signals. The compressor utilizes a heavily overlapped filter bank, which is the core of the invention. This filter bank effectively filters the input signal into multiple overlapping frequency bands. The design minimizes ripple in the frequency response, achieving levels below about 2 dB, 1 dB, or even 0.5 dB with increased overlap. Each frequency band is processed through a power estimator, which generates a power signal. These power signals are then used to calculate gain for dynamic range compression, resulting in scaled bands that are summed to produce the final output signal.
