Abstract
An audio processing apparatus and method for a mobile device are provided. The audio processing apparatus and method may appropriately determine sound source localizations corresponding to a voice signal and an audio signal, and thereby may simultaneously provide a voice call service and a multimedia service. Also, the audio processing apparatus and method may guarantee quality of the voice call service even when simultaneously providing the voice call service and the multimedia service.
Claims21
An audio processing apparatus for a mobile device, the audio processing apparatus comprising:
- a signal providing unit to provide a voice signal and at least one audio signal distinguishable from the voice signal, wherein the voice signal is a monaural signal and the at least one audio signal is a stereo signal and wherein the signal providing unit comprises a frame adjustment unit to adjust a frame size of the voice signal and the at least one audio signal to be substantially identical;
- and
- a sound source localization unit to determine sound source localizations corresponding to the voice signal and the at least one audio signal.
An audio processing apparatus for a mobile device, the audio processing apparatus comprising:
- a signal providing unit to provide a voice signal and at least one audio signal distinguishable from the voice signal, wherein the voice signal is a monaural signal and the at least one audio signal is a stereo signal and wherein the signal providing unit further comprises:
- a frame adjustment unit to adjust a frame size of the voice signal and the at least one audio signal to be substantially identical;
- and
- a rate adjustment unit to adjust the voice signal and the at least one audio signal to have a substantially identical sampling rate;
- and
- a sound source localization unit to determine sound source localizations corresponding to the voice signal and the at least one audio signal.
An audio processing method for a mobile device, the audio processing method comprising:
- providing a voice signal and at least one audio signal distinguishable from the voice signal, wherein the voice signal is a monaural signal and the at least one audio signal is a stereo signal
- adjusting a frame size of the voice signal and the at least one audio signal to be substantially identical;
- and
- determining sound source localizations corresponding to the voice signal and the at least one audio signal using the mobile device.
A computer-readable recording medium storing computer readable code including a program for implementing an audio processing method for a mobile device, the audio processing method comprising:
- providing a voice signal and at least one audio signal distinguishable from the voice signal, wherein the voice signal is a monaural signal and the at least one audio signal is a stereo signal;
- adjusting a frame size of the voice signal and the at least one audio signal to be substantially identical;
- and
- determining sound source localizations corresponding to the voice signal and the at least one audio signal.
