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.
