Patent ID: 8553893

Claim:
A sound processing device comprising: an inputting section that inputs L-ch audio data and R-ch audio data; a delaying section that delays the L-ch audio data and the R-ch audio data by a delay time ranging from 62.5 microsecond to 125 microsecond; a first adding section that adds the L-ch audio data delayed by the delaying section to the L-ch audio data input by the inputting section; a second adding section that adds the R-ch audio data delayed by the delaying section to the R-ch audio data input by the inputting section; a first phase adjusting section that adjusts a phase of the L-ch audio data added by the adding section into a phase that is inverted in phase from a phase of the L-ch audio data input by the inputting section; a second phase adjusting section that adjusts a phase of the R-ch audio data added by the adding section into a phase that is inverted in phase from a phase of the R-ch audio data being input by the inputting section; a first outputting section that adds the L-ch audio data whose phase is adjusted by the first phase adjusting section to the R-ch audio data input by the inputting section and outputs resultant R-ch audio data; and a second outputting section that adds the R-ch audio data whose phase is adjusted by the second phase adjusting section to the L-ch audio data input by the inputting section and outputs resultant L-ch audio data.
