Title:
An encoding method, a decoding method, coding equipment, a decoding device, a program, and a recording medium
Document Type and Number:
Japanese Patent JP6053196
Kind Code:
B2
Abstract:
A frequency-domain sample interval corresponding to a time-domain pitch period L corresponding to a time-domain pitch period code of an audio signal in a given time period is obtained as a converted interval T1, a frequency-domain pitch period T is chosen from among candidates including the converted interval T1and integer multiples U × T1of the converted interval T1, and a frequency-domain pitch period code indicating how many times the frequency-domain pitch period T is greater than the converted interval T1is obtained. The frequency-domain pitch period code is output so that a decoding side can identify the frequency-domain pitch period T.
