Abstract
A sound processing apparatus includes: a conversion unit that samples predetermined audio data with a first quantization bit rate and a second quantization bit rate greater than the first quantization bit rate and outputs the respective results as first digital audio data and second digital audio data; a frequency analysis unit that performs frequency analysis on each output from the conversion unit; and a determination unit that performs predetermined determination processing on the basis of analysis results by the frequency analysis unit.
Claims15
A sound processing apparatus comprising:
- a conversion unit configured to sample predetermined audio data with a first quantization bit rate and a second quantization bit rate greater than the first quantization bit rate and output respective results as first digital audio data and second digital audio data;
- a frequency analysis unit configured to perform frequency analysis on each output from the conversion unit;
- and
- a determination unit configured to perform predetermined determination processing on a basis of analysis results by the frequency analysis unit.
A sound processing method comprising:
- by a conversion unit, sampling predetermined audio data with a first quantization bit rate and a second quantization bit rate greater than the first quantization bit rate and outputting respective results as first digital audio data and second digital audio data;
