Abstract: Various embodiments disclose a computer-implemented method for determining, for each of a plurality of sound sources near a user selected location, a distance between the user selected location and a location of the sound source. The computer-implemented method also includes determining an amplitude of each sound source in the plurality of sound sources based on the determined distance between the user selected location and the location of the sound source and mixing the plurality of sound sources based on the determined amplitudes.

Abstract: A separable shoulder rest assembly for stringed instruments comprises a base component with receiving apertures and positioning feet, and a removable component with engagement protrusions and keyed apertures for secure attachment in predetermined orientation. An instrument interface assembly includes an elastomeric insert with engagement protrusions and contact pads positioned within a recessed cavity to minimize instrument contact area while providing secure engagement. A lockable ball joint mechanism enables multi-directional rotational adjustment for enhanced positioning flexibility. The separable design enables component customization and replacement while maintaining structural integrity and operational performance.

Abstract: The instant invention, the earth anchor, is comprised of a foundation plate, a connecting column, a strap anchor guide, a strap anchor bolt (pin) and a strap anchor. The foundation plate is an essentially flat metal plate that is permanently affixed to the bottom of the connecting column. The connecting column is a hollow cylinder that extends the length of the excavated opening. The strap anchor bolt is secured through the connecting column by an opening formed in the connecting column near the top of the connecting column. The foundation plate, the connecting column, the strap guide anchor and the strap anchor bolt (pin) are manufactured from a metallic or rigid polymeric material. The strap anchor is a flexible material that extends around the strap anchor bolt (pin) and around the back or side ground shoe (bar) when used in an application involving the securing of a sports goal.
