Title:
SOUND SIGNAL PROCESSING DEVICE AND SOUND SIGNAL PROCESSING METHOD
Document Type and Number:
Japanese Patent JPH1153841
Kind Code:
A
Abstract:
To improve acoustic quality while the complexity of a circuit, etc., is suppressed.
Sound data signals DL, DR and DC whose sampling frequency is 96 kHz and sound data signals DSW, DSL and DSR whose sampling frequency is 48 kHz are outputted from a sound data signal output circuit 51. The sound data signals DL, DR and DC whose sampling frequency is 96 kHz are inputted to a digital signal output circuit 54 through a delay circuit 53 and the sound data signal DSW, DSL and DSR whose sampling frequency is 48 kHz are inputted to the digital signal output circuit 54 after their sampling frequency is transformed into 96 kHz by a frequency transformation circuit 52.
