A method and system for improved acoustic transmission of data

A method for communicating data acoustically, comprising:

• a) segmenting the data into a sequence of symbols;
• b) encoding each symbol of the sequence into a plurality of tones, wherein each of the plurality of tones for each symbol in the sequence are at a different frequency;
• and
• c) acoustically generating the plurality of tones simultaneously for each symbol in sequence.

A system for communicating data acoustically, comprising:

• an encoding device, comprising:
• one or more first processors;
• and
• a first tangible, non-transitory, computer-readable medium storing instructions that, when executed by the one or more first processors, cause the encoding device to perform functions comprising:
• a) segmenting the data into a sequence of symbols;
• and
• b) encoding each symbol of the sequence into a plurality of tones, wherein each of the plurality of tones for each symbol in the sequence are at a different frequency;
• and
• a playback device, comprising:
• one or more second processors;
• a speaker;
• and
• a second tangible, non-transitory, computer-readable medium storing instructions that, when executed by the one or more second processors, cause the playback device to perform functions comprising:
• causing, via the speaker, playback of the plurality of tones simultaneously for each symbol in sequence.
