Abstract
A method and an apparatus for processing an audio signal in a mobile terminal are provided, wherein an audio signal received from a counterpart mobile terminal is classified into a voice signal and a noise signal according to respective energy, and a frequency of the classified voice signal and an energy of the classified noise signal is controlled according to a predetermined criteria, then the controlled voice signal and the controlled noise signal are coupled and output to a speaker.
Claims12
A method for processing an audio signal in a mobile terminal, the method comprising:
- classifying an audio signal received from a counterpart mobile terminal into a voice signal and a noise signal according to respective energy level;
- controlling a frequency of the voice signal from the counterpart mobile terminal to not overlap with a voice signal from a microphone of the mobile terminal;
- controlling the energy of the noise signal from the counter mobile terminal according to energy of a noise signal from the microphone of the mobile terminal;
- and
- coupling the controlled voice signal and the controlled noise signal to output the same to a speaker.
An apparatus for processing an audio signal in a mobile terminal, comprising:
- a detector for classifying an audio signal received from a counterpart mobile terminal into a voice signal and a noise signal according to an energy;
- an equalizer for controlling a frequency of the voice signal from the counterpart mobile terminal to not overlap with a voice signal from the mobile terminal;
- a noise gain controller for controlling the energy of the noise signal from the counter mobile terminal according to energy of a noise signal from a microphone of the mobile terminal ;
- and
- a digital-to-analog converter for coupling the controlled voice signal and the controlled noise signal to output the same to a speaker.
