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.
Claims12
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.
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.
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.
