Latest Patents
Ridder's latest patents include an Adaptive Bass Processing System and an Acoustic Feedback Canceller. The Adaptive Bass Processing System is an effective and simple psychoacoustic bass generation system that generates a harmonic signal. This system ensures that inter-modulation remains below a threshold level and includes a high-pass filter designed to pass harmonics that can be reproduced with fidelity by loudspeakers or other transducers. Additionally, it features a loudness matching block that compensates for the loudness of the desired harmonics to match the original signal. The Acoustic Feedback Canceller addresses the issue of howling sounds, which can disrupt speech and music. In this invention, microphone signals are converted to the frequency domain, where howling frequencies are detected and estimated using howling to noise ratios. A notch filter, adaptively designed for the howling frequency, is then applied to effectively remove the howling.
