摘要： A sound quality correcting apparatus includes: an input module; a feature quantity calculator; a score calculator; a modulation spectrum power calculator; a score corrector; and a signal corrector. The input module receives an input audio signal. The feature quantity calculator calculates feature quantities of the input audio signal for each of a plurality of first intervals having a certain time length. The score calculator calculates a score value for each the first interval based on the feature quantities. The modulation spectrum power calculator calculates a power value, at a certain modulation frequency, of a modulation spectrum of the input audio signal. The score corrector corrects score values in the plurality of first intervals that belong to a second interval if a power value calculated in the second interval is larger than or equal to a certain value. The signal corrector corrects the audio signal based on the score values.

摘要： A musical scale recognition apparatus includes an analog/digital converter and a processor, and can determine by the processor how close an input analog audio signal is to a musical scale of a musical tone to be recognized by repeatedly performing a calculation of a cumulative value As to find a coefficient of a Fourier sine series of the audio signal on the basis of a frequency f and digital data D, a cumulative value Ac to find a coefficient of a Fourier cosine series of the audio signal on the basis of the frequency f and the digital data D, and a frequency power spectrum effective value A of the audio signal on the basis of the cumulative value As and the cumulative value Ac, wherein the digital data into which the input analog audio signal is converted by the analog/digital converter is D, the frequency (musical scale) of the musical tone to be recognized is f, and a current time is t. At this time, A is a value which shows how close the input audio signal is to the musical sound to be recognized, and it is shown that the larger the value A becomes, the closer the both sides are.

摘要： In a sound effect applying apparatus, an input part frequency-analyzes an input signal of sound or voice for detecting a plurality of local peaks of harmonics contained in the input signal. A subharmonics provision part adds a spectrum component of subharmonics between the detected local peaks so as to provide the input signal with a sound effect. An output part converts the input signal of a frequency domain containing the added spectrum component into an output signal of a time domain for generating the sound or voice provided.with the sound effect.
