Redundant, low-latency digital audio transmission

A method for redundant, low-latency transmission of one or more digital audio streams, the converter device, the method comprising:

• receiving an analog audio signal;
• digitizing the analog audio signal into a stream of digital audio samples;
• encoding the digital audio samples into a stream of digital audio values forming a sequence of digital audio values, each digital audio value having an audio-value position, the audio-value position indicating a position of the digital audio value in the sequence;
• generating, using at least one processor of a machine, a stream of digital audio data packets from the stream of digital audio values, each of the digital audio data packets including a current digital audio value and a plurality previous digital audio values of the stream of digital audio values where, for each of the digital audio data packets, each of the plurality of previous digital audio values precede the current digital audio value in the sequence of digital audio values by a respective prime number of digital-audio positions, such that in each of the digital audio data packets the plurality of previous digital audio values each have a different audio-value position for interference resistance to a periodic noise or communication source;
• and
• transmitting the stream of digital audio data packets to a receiving device.

A non-transitory computer-readable medium comprising instructions for receiving redundant low-latency transmission of one or more digital audio streams, the instructions, when executed on at least one processor of a mobile communication device, cause the mobile communication device to:

• receive a plurality of encoded audio values comprising multiple copies of each of a sequence of encoded audio values representing an audio signal, each of the sequential encoded audio values having an audio-value position, the audio-value position indicating a position of the encoded audio value in the sequence, and at least one of the multiple copies of an encoded audio value is received in a data packet that includes a plurality of encoded audio values in the sequence, the plurality of encoded audio values including a current encoded audio value and a plurality of previous encoded audio values each having an audio-value position that precedes the current encoded audio value in the sequence by a respective prime number of audio-value positions, such that each of the plurality of previous encoded audio values have a different audio-value position for interference resistance to a periodic noise or communication source;
• store one of the multiple copies of each of the sequence of encoded audio values in a first buffer;
• decode each stored copy of each of the sequence of encoded audio values to generate a stream of digital audio samples;
• store each of the stream of digital audio samples in a queue;
• and
• forward the stream of digital audio samples from the queue for presentation to a user of the mobile communication device.
