Embodiment Construction

[0015] As required, detailed embodiments of the invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary embodiments of the invention which can be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

[0016] The sound processor may include a test tone generator configured to provide a test signal, such as white noise, pink noise, a frequency sweep, a continuous noise signal, or some other audio signal. A test signal may be provided to one or more loudspeakers in the venue to generate audio output. This audio output can be picked up by one or more microphones at various points i...

Abstract

Mobile devices may capture audio signals indicative of test audio received by an audio capture device of the mobile device; and send the captured audio and the zone designation to a sound processor to determine equalization settings for speakers of the zone of the venue. An audio filtering device may receive the captured audio signals from the mobile devices; compare each of the captured audio signals with the test signal to determine an associated reliability of each of the captured audio signals; combine the captured audio signals into zone audio data; and transmit the zone audio data and associated reliability to a sound processor configured to determine equalization settings for the zone based on the captured audio signals and the test signal.

Description

technical field [0001] Aspects disclosed herein generally relate to collecting crowdsourced equalization data for determining field equalization settings. Background technique [0002] Loudspeaker interaction in the environment may cause the frequency response of the loudspeaker to change. In an example, as multiple speakers are added to the venue, speaker output at different locations may increase or decrease constructively, causing comb filtering or other irregularities. In another example, speaker outputs may experience altered frequency responses due to room interactions such as room crosstalk, echoes, and echoes. These effects may be different at different venues, and may even be different at different locations within the venue. [0003] Sound equalization refers to a technique whereby the amplitude of an audio signal at specific frequencies is increased or decreased. Sound engineers use equipment to perform sound equalization to correct frequency response effects c...
