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.
Claims19
An audio enhancement circuit for enhancing an audio signal from a source, comprising:
- a plurality of first amplifiers interconnected to one another by a plurality of circuit components, wherein each first amplifier in the plurality of first amplifiers is disposed within a feedback loop having a portion of the feedback loop connecting to the first amplifier via the non-inverting input of the individual amplifier and at least one second amplifier is directly coupled to a variable resister via its non-inverting input;
- wherein the audio signal travels through at least one feedback loop and at least one first amplifier.
An audio transmitter, comprising:
- a microphone and an enhancement circuit, wherein the enhancement circuit comprises:
- a power circuit comprising at least one DC voltage conversion element;
- and
- a plurality of amplifiers, wherein at least one of the plurality of amplifiers is powered by a DC voltage, at least one of the plurality of amplifiers receives at least one signal representative of a sound received through the audio transmitting device via a feedback loop coupled at a non-inverting input of at least one of the plurality of amplifiers, and a second plurality of amplifiers with a feedback loop coupled at a non-inverting input of at least one of the second plurality of amplifiers.
