Abstract: A method of enhancing audio sound. The method includes sensing an acoustic signal using a microphone in an electronic device. The acoustic signal is emitted in response to a primary sound signal and transmitted as a sound wave through a space. The method further includes receiving, using an antenna in the electronic device, a wireless signal encoded with the primary sound signal. An impulse response for the space is estimated based on the sensed acoustic signal and the primary sound signal encoded within the received wireless signal. A delay between the sensed acoustic signal and the primary sound signal encoded within the received wireless signal is calculated based on the estimated impulse response. The primary sound signal encoded within the received wireless signal is delayed using the calculated delay and reproduced to enhance the acoustic signal heard by a user of the electronic device.

Abstract: A photographic color effects lighting filter system made up of a series of lighting filters which are designed to be placed in front of one or more lighting sources. The lighting color effects filter series is made up of groups of filters wherein each of the filter groups is composed of a plurality of filters wherein each filter within a given group provides selective absorption of light having a color corresponding to one of the primary, secondary or intermediary colors. Each of the filters within a given group has a specific effective absorption density. The effective absorption densities are calibrated so that the selected absorption densities are the same for each of the different color groups.
