ABSTRACT:
The present invention discloses methods and systems for providing very high quality audio playback using all-digital wireless paths from a source to speaker transducers and/or headphones located anywhere within a distance allowed by the FCC. Each speaker has a separate digital amplifier dedicated to each transducer within it (e.g. woofer, tweeter). The present invention also discloses a system that provides a data link capable of sending an all-digital, full-bandwidth, signal from the original digital source material to each separate transducer in the system without using sound degrading lossy data compression. This system is designed to read, broadcast, and reproduce with accurate audio loudspeaker time-alignment (<100 uS) and low overall latency (less than 7 milliseconds) all popular audio formats in full-bandwidth and without data compression in the effort to maintain the integrity of the entire audio signal, wherein the audio signal may include an accompaniment to a player piano.
