The present invention relates to a method for communicating data acoustically. The method includes segmenting the data into a sequence of symbols; encoding each symbol of the sequence into a plurality of tones; and acoustically generating the plurality of tones simultaneously for each symbol in sequence. Each of the plurality of tones for each symbol in the sequence may be at a different frequency.
The present invention relates to a method for receiving data transmitted acoustically. The method includes receiving an acoustically transmitted signal encoding data; processing the received signal to minimise environmental interference within the received signal; and decoding the processed signal to extract the data. The data encoded within the signal using a sequence of tones. A method for encoding data for acoustic transmission is also disclosed. This method includes encoding data into an audio signal using a sequence of tones. The audio signal in this method is configured to minimise environmental interference. A system and software are also disclosed.
The present invention relates to a method of triggering an event. The method includes receiving a signal stream, detecting a trigger point within the signal stream using a fingerprint associated with the trigger point and triggering an event associated with the detected trigger point.

METHOD AND SYSTEM FOR ACOUSTIC COMMUNICATION OF DATA
The present invention relates to a method for receiving data transmitted acoustically. The method includes the steps of receiving an acoustically transmitted signal; and decoding the signal using, at least, a first plurality of voters to extract the data. The first plurality of voters comprise differing values for a first acoustic characteristic to address interference. A system and software are also disclosed.

The present invention relates to a method for authenticating a device with a wireless access point. The method includes receiving an audio signal at the device via a microphone; processing the audio signal to extract a code; using the code to authenticate the device, at least to part, with the wireless access point; and in response to the authentication, providing access to one or more network services to the device via the wireless access point A system and software are also disclosed.

The present invention relates to systems for communicating data. In particular, systems for communicating data to and from mobile devices are described. One system involves the use of a server to store the association between a shortcode and the data. A user device can be used to transmit the shortcode to a second user device. The second user device can then access the association at the server to access the data. The shortcode is transmitted via an audibly unique signal between the two devices. Further devices, systems, and methods for redeeming vouchers, transferring money, unlocking content on a device, and authenticating transactions all using audio are also disclosed. A method for managing data communication on a mobile device is further disclosed. In addition, a system for asynchronous transmission of the data is disclosed by use of reserving a shortcode at a server before the shortcode is associated with data.
