Title: INFORMATION PROCESSING DEVICE, METHOD, AND PROGRAM
Abstract:
The present feature relates to an information processing device, method, and program with which it is possible to suppress an increase in a user's burden while suppressing a reduction in subjective tone quality. The peak-to-rms ratio of an inputted audio signal is calculated and, when the calculated peak-to-rms ratio is smaller than a prescribed threshold, an expander process for further reducing a signal value smaller than the prescribed threshold is performed on the audio signal. The present disclosure can be applied to, for example, an information processing device, an electronic apparatus, a computer, a server, a program, a recording medium, and a system, etc.
