Abstract
Methods and systems for encoding and decoding audio signals are described. In one embodiment, a first DTMF tone in an audio signal may be identified and decoded. A second DTMF tone in the audio signal may be identified and decoded at a time delay from the first DTMF tone. A requested action is determined for an electronic figurine associated with the first DTMF tone and the second DTMF tone. The second DTMF tone is different than the first DTMF tone. Additional methods and systems are disclosed.
Claims30
A method comprising:
- encoding a first portion of an audio signal with a first dual-tone multi-frequency (DTMF) tone;
- and
- encoding a second portion of the audio signal with a second DTMF tone at a time delay from the first DTMF tone, the second DTMF tone being different than the first DTMF tone.
A method comprising:
- identifying and decoding a first DTMF tone in an audio signal;
- identifying and decoding a second DTMF tone in the audio signal at a time delay from the first DTMF tone;
- and
- determining an action for an electronic figurine associated with the first DTMF tone and the second DTMF tone,
- wherein the second DTMF tone is different than the first DTMF tone
A method comprising:
- receiving through a radio frequency receiver on a mobile electronic device, at a frequency, a transmission of an encoded audio signal;
- processing the encoded audio signal on the mobile electronic device to decode an encoded data trigger on a subcarrier of the frequency from the encoded audio signal;
- audibly receiving through a microphone on the mobile electronic device an additional audio signal;
- verifying the encoded data trigger based on receipt of the additional audio signal;
- enabling an action on the mobile electronic device based on verification;
- and
- performing the action on the mobile electronic device based on enablement of the action and the encoded data trigger.
A machine-readable medium comprising instructions, which when executed by one or more processors, cause the one or more processors to perform the following operations:
- identify and decode a first DTMF tone in an audio signal;
- identify and decode a second DTMF tone in the audio signal at a time delay from the first DTMF tone;
- and
- determine a requested action for an electronic figurine associated with the first DTMF tone and the second DTMF tone,
- wherein the second DTMF tone is different than the first DTMF tone.
