Claim:
1. A method of converting an analog input signal to a high fidelity digital output signal, comprising the steps of: transmitting an analog input signal from an analog signal source; providing the analog input signal in at least two stages having distinct levels of amplification; converting each resultant amplified analog input signal to a digital input signal for the respective stage, wherein the digital input signal for the respective stage comprises digital data samples; assigning the digital data samples for each stage to correspond to a frame in dependence on when they are received, wherein the time period of each frame is interchangeable between stages; applying a window function overlapping in time to each frame of data to create windowed data packets for each respective stage; providing the windowed data packets as inputs to a combiner; selecting a windowed data packet for one of the stages to be used by the combiner to generate the digital output signal.
