Abstract
An exemplary audio enhancement system substantially eliminates latency by returning audio input signals in amplified form directly in the analog domain to the source, thereby reducing signal degradation and removing redundancy from digital and analog audio transmission and processing architectures.
Claims20
An audio enhancement circuit for enhancing an audio signal from a source, comprising:
- a decoupling circuit element connected in series to a non-inverting input of a first amplifier powered by a DC voltage;
- a variable resistor by which the audio signal travels from the first amplifier to a second amplifier, wherein the second amplifier is coupled to a feedback loop, the second amplifier being coupled at its output to a transmitter of enhanced sound to the source.
A method of audio enhancement, the method comprising the steps of:
- transmitting audio signals to an enhancement circuit;
- transmitting enhanced audio signals to a user;
- and
- maintaining latency between audio signal transmission and enhanced audio signal transmission below approximately 3.0 ms.
An audio enhancement system, comprising:
- a microphone;
- a communication device for communicating the sound received at the microphone;
- and
- an enhancement circuit coupling the microphone to the communication device, the enhancement circuit comprising:
- a DC power source;
- and
- a plurality of amplifiers, wherein at least one of the plurality of amplifiers is powered by the DC power source and at least one of the plurality of amplifiers receives a signal representative of the sound via its non-inverting input.
The audio enhancement system of claim 18 has at least four amplifiers.
The audio enhancement system of claim 19 has at least five amplifiers.
