System and method for detecting analog signals on an amplifier input and gating the same
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.
1 . A method 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, wherein the step of determining comprises:
measuring a peak value of the received at least one audio analog signal level and comparing the measured peak value to a predetermined peak value.
2 . The method according to claim 1 , wherein the step of gating comprises:
disregarding any output from the input channel in which the received audio signal level is below the predetermined value.
3 . The method according to claim 1 , wherein the step of gating comprises:
grounding the input of the input channel in which the received audio signal level is below the predetermined value.
4 . An audio processing system that includes at least one amplifier, comprising:
at least one processor that is part of the amplifier;
a memory operatively connected with the at least one processor, wherein the memory stores computer-executable instructions that, when executed by the at least one processor, causes the at least one processor to execute a method that comprises:
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, wherein the step of determining comprises:
measuring a peak value of the received at least one audio analog signal level and comparing the measured peak value to a predetermined peak value.
5 . The system according to claim 4 , wherein the step of gating comprises:
disregarding any output from the input channel in which the received audio signal level is below the predetermined value.
6 . The system according to claim 4 , wherein the step of gating comprises:
grounding the input of the input channel in which the received audio signal level is below the predetermined value.
7 . A method 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, wherein the step of determining comprises:
measuring an average value of the received at least one audio analog signal level and comparing the measured average value to a predetermined average value.
8 . The method according to claim 7 , wherein the step of gating comprises:
disregarding any output from the input channel in which the received audio signal level is below the predetermined value.
9 . The method according to claim 7 , wherein the step of gating comprises:
