In the improved pitch-estimation method, 1200 log2 h and exp[?(x?(F+1200 log2 h))2/2W2] in the following expression are computed in advance and then stored in a memory of a computer: c ? ? ( t ) ? ( h ? F , m ) ? 1 2 ? ? ? ? W 2 ? exp ( - ( x - ( F + 1200 ? ? log 2 ? h ) ) 2 2 ? W 2 ) ( 61 ) The above expression is computed only with respect to a fundamental frequency F wherein x?(F+1200 log2 h) is close to zero. With this arrangement, computations to be performed may considerably be reduced, and computing time may accordingly be shortened.

Abstract: In a pitch estimation apparatus, a function estimation part estimates a fundamental frequency probability density function of an audio signal by repeating a weight calculation process and an estimated shape specification process. The weight calculation process calculates a weight of each tone model of each fundamental frequency based on an estimated shape of each tone model of each fundamental frequency. The estimated shape indicates a degree of dominancy of a corresponding tone model in a total harmonic structure of the audio signal. The estimated shape specification process specifies each estimated shape of each tone model based on an amplitude spectrum of the audio signal, the harmonic structure of each tone model and the weight of each tone model. A similarity analysis part calculates a similarity index value indicating a degree of similarity between each tone model and corresponding estimated shape.
