Abstract: For each audio pairing broadcast from an electronic device, reporting broadcasted pairing data including: broadcaster device group, broadcast data element, and broadcaster volume setting. For each reception, reporting received pairing data, including: receiver device group, received data element, and received signal score. Matching each received pairing data with zero or one instances of broadcasted pairing data based on a received data element matching the broadcast data element. For each broadcaster reporting a particular group and volume setting, identifying a received signal score value corresponding to a predetermined percentile of a density distribution of such scores matching broadcasters of the particular group. Determining, for each broadcaster of the group, a volume based on: the received signal score corresponding to the predetermined percentile and a reference received signal score. Transmitting, to each broadcaster of the group, instructions to conform the broadcasting device to the determined volume setting.

Abstract: During audio pairing with a broadcaster computing device, a receiver computing device receives audio token data broadcast by the broadcaster computing device via audio communication channels and displays a broadcaster computing device status category to the user via a graphical user interface. In some examples, the receiver computing device receives audio token and determines a broadcaster computing device status category based on determining results of a CRC on the received audio token data. In other examples, the receiver computing device determines a signal score for the received audio token data and determines a broadcaster computing device status category based on the value of the signal score as compared to low and high threshold signal scores determined by an account management system based on aggregate signal score data received from multiple receiver computing devices of a same model as the receiver computing device.

Abstract: An operator selects an application on a first user computing device to request a data transfer with a second user computing device. The first user computing device broadcasts an audio token comprising data. The first user computing device activates a microphone component, successively cycles through available audio configurations, applies each selected audio configuration to received audio token data, determines a signal score for each applied audio configuration, and transmits processed audio token data and signal scores to an account management system. The account management system also receives processed audio token data from multiple other computing devices of the same model as the first user computing device. The account management system selects a default audio configuration for the model based on the determined signal scores. The account management system transmits instructions to known computing devices of the model to apply the default audio configuration to future reception of audio token data.

Abstract: The system and method described provide correction of modulation symbol errors which may occur during audio pairing of computing devices. The transmission between the computing devices comprises a six modulation symbol (24 bit) token containing transaction information and a two check symbol (8 bit) cyclic redundancy check ("CRC"). Error probabilities of symbols are be used to identify probable symbol error locations and the number of errors contained in the received transmission during the symbol decoding process. If there is a single modulation symbol error, the 16 possible combinations of bit values are cycled through until one combination passes the CRC check. If there are two modulation symbol errors, the 256 possible combinations of bit values are cycled through until two combinations pass the CRC check.
