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.

Abstract: The present disclosure discloses a method for controlling web application through a smart terminal and a smart terminal for controlling web application. In the method, the smart terminal notifies the server device to enter the audio control mode after the authentication and registration of the server device. The smart terminal receives an audio input signal and detects a signal level of the audio input signal. The smart terminal notifies the server device to trigger control of corresponding web application, based on the detected signal level. The present disclosure enables a smart terminal to control computer programs. The smart terminal can control web applications by a mobile phone audio transducer. The method facilitates user convenience in the control of web application on a computer by an audio transducer of a smart phone, and improves the flexibility of web application control.
