Abstract: A system and method are described herein for gating at least one input to an amplifier, the method comprising: measuring at least one audio analog signal level received by the amplifier at a first input; determining whether the received at least one audio analog signal level is below a predetermined threshold level; and gating the first input such that the received audio analog signal level is ignored in further processing by the amplifier.

Abstract: Described herein are a method and security enhancing device for a bi-directional communications device, comprising: an M-digit display; a processor; a security software application (security App) adapted to be stored in memory and executed by the processor; an N-digit random number generator adapted to periodically generate a new N-digit random number and transmit the same to the processor and the security App, and wherein the processor is further adapted to transmit the N-digit random number to the display to display the N-digit random number; and a wireless communications transceiver and antenna (wireless communications device) adapted to transmit and receive wireless communications to and from, respectively, one or more personal electronic devices that are adapted to wireless communicate using identical communications protocols as the wireless communications transceiver, and wherein the security App is adapted to receive and store the N-bit digit random number that changes periodically, and wherein the security App is adapted to generate an offer to join the meeting message that is transmitted by the wireless communications transceiver to the one or more personal electronic devices, and wherein the security App is adapted to receive a request to join the meeting message from a first personal electronic device, wherein the request to join the meeting message comprises a field within which a currently displayed N-digit random number can be entered into (request to join N-digit random number), and wherein the security App is further adapted to compare the received request to join N-digit random number to the stored N-digit random number, and if they match, then the security App provides a communication to the processor to allow bi-directional communications with the personal electronic device that transmitted the received N-digit random number.

Abstract: A system and method are provided herein for dynamically adjusting delay in an audio distribution system, the method comprising: determining what audio processing devices comprise each of a plurality of audio data channels, wherein each of the plurality of audio data channels comprises a path from a digital audio receiving device to a back end audio playing device; obtaining digital audio processing delays for each of the audio processing devices for each of the audio data channels; determining which of the audio data channels has the greatest delay in processing and transmitting digital audio data signals (digital audio data processing delay) prior to broadcasting the digital audio data signals as acoustic audio signals; determining a difference between the audio data channel with the greatest digital audio data processing delay and each of the remaining audio data channels (delay difference per channel); and adding a delay to each digital audio word in each different audio channel that substantially equalizes the digital audio data processing delay between each of the different audio data channels.
