Systems and methods for audio device interoperability
Systems and methods of the present disclosure enable heterogenous device interoperability for signaling across a network by configuring each transmitter and receiver to implement an interoperability tranche protocol. According to the interoperability tranche protocol, a transmitter generates multiple audio streams based on an original audio signal and a tranche function, where the tranche function is configured to produce the audio streams from the original audio signal at different quality levels. The transmitter transmits the audio streams across a network to each receiver on the network. According to the interoperability tranche protocol, each receiver receives the audio streams and generates an output audio signal based on an interpolator function and the audio streams. The interpolator function combines the audio streams and interpolates missing data from at least one of the audio streams using data from at least one other of the audio stream.
