A technique for reducing inherent noise in a real time digital audio
wireless system. The technique allows for low power stereo analog to
digital and digital to analog converters to be used in a battery operated
real time digital audio wireless applications. The audio signal is sent
to the left and right channels of an analog to digital converter with a
preceding audio amp of different gain at the input to each channel. The
signals are simultaneously digitized then combined to generate a new
digital value resulting in noise reduction at lower amplitudes. This new
data word is then transmitted via radio waves to a digital audio
receiver. Once the data is received it is output simultaneously to a
stereo digital to analog converter. The digital to analog conversion of
both left and right channels is then summed using a resistor network and
an audio amplifier. The audio amplifier output is then reduced to create
further reduction of noise at all amplitudes.
