  • Patent number: 9930164
    Abstract: A system for processing a sound signal includes a mobile terminal that obtains a series of sound waveform values in a first location. The mobile terminal obtains a sound waveform value within a valid sound waveform value range from the series of sound waveform values and transmits the sound waveform value to a computing device in a second location, so that the computing device performs a logic operation corresponding to the sound waveform value. A mobile terminal can transmit a sound waveform value to a computing device at a location remote from the mobile terminal to perform a logic operation corresponding to the sound waveform value, and total system performance, including the computing device and the mobile terminal, is improved.
