音声波形符号器。 As an encoder in a method that encodes audio waveforms and expresses the repetition of similar waveforms by a code string for one waveform and the number of repetitions, it samples the analog original sound signal at a frequency that is an integral multiple of the sampling frequency during synthesis. An audio waveform encoder characterized in that, after analyzing the waveform, encoding is performed at a sampling frequency during synthesis.
