Latest Patents
One of Griesinger's latest patents is a multichannel downmixing device. This innovative downmixer provides listeners with a substantially accurate rendition of the apparent direction and relative loudness of an input signal. By downmixing certain channels of the input signal independently, the device preserves the energy and intended direction of the sound. Additionally, the downmixer includes a test downmixer that operates over a limited frequency range, enhancing the accuracy of loudness perception for listeners while demanding fewer resources for operation.
Another notable patent is the sound event detection and localization system using power analysis. This system models the beginning detection, accommodation, and frequency bias properties of the human hearing mechanism. It can detect directional transients, or sound events, in a sound field and localize them effectively. The system differentiates between sound events and non-sound events, localizing them based on their respective properties. This innovative approach allows for a more nuanced understanding of sound dynamics in various environments.
