Abstract
A sound processing device includes: a distance information obtaining unit which obtains information about a first distance between stereo microphones and information about a second distance between stereo loudspeakers; and a signal processing unit which processes a stereophonic audio signal collected by the stereo microphones according to the first distance and the second distance to adjust a stereo effect provided when the stereophonic audio signal is reproduced from the stereo loudspeakers.
Claims16
A sound processing device, comprising:
- an obtaining unit configured to obtain information about a first distance between stereo microphones and information about a second distance between stereo loudspeakers;
- and
- a signal processing unit configured to process a stereophonic audio signal according to the first distance and the second distance to adjust a stereo effect provided when the stereophonic audio signal is reproduced from the stereo loudspeakers, the stereophonic audio signal being collected by the stereo microphones,
- wherein the signal processing unit is configured to perform first signal processing on the stereophonic audio signal, when a value of a ratio of the second distance to the first distance is less than a threshold value, the first signal processing increasing the stereo effect.
