The present invention generates data series indicating respective combined-wave data pieces by a first step of obtaining a reference time length as a reference of a time length of one combined wave, a sampling interval time, and a frequency fluctuation rate, a second step of calculating a total number of samples in the data series indicating the one combined wave on the basis of the reference time length, the sampling interval time, and the frequency fluctuation rate, a third step of calculating a rotation angle with respect to the sampling interval time on the basis of the total number of samples for each of plural sound data pieces, a fourth step of calculating combined values for the total number of samples, the combined values being obtained by combining respective values of the plural sound data pieces, the values being calculated on the basis of the rotation angles for the respective sampling interval times, a fifth step of generating a series of the combined values for the total number of samples for the respective sampling time intervals as a data series of the one combined-wave data piece, and performing a sequence of the processes of the second to the fifth steps by a predetermined times while changing the frequency fluctuation rate every time when the sequence of the processes is executed once.

An audio information playback method includes reading audio information, reading separator information, acquiring note-on information and note-off information, moving a playback position, and starting playback. The starting of the playback is from the loop end position to the playback end position of an utterance unit subject to playback in response to acquisition of the note-off information corresponding to the note-on information.

An electronic drum-module for connection to electronic-drum pads is provided. The module includes an electronic display, a memory storing audio files for playback when the playback is triggered by a signal received from the pads, and one or more processors coupled to the electronic display and the memory. The processors are configured to play a portion of the one or more audio files when the playback is triggered by the signal received from the pads and to display, on the electronic display, a user interface for an application. The user interface includes a waveform associated with recorded audio. The user interface includes a sample-start marker and a sample-end marker. A portion of the waveform between the sample-start marker and sample-end marker is displayed brighter than a portion not between the sample-start marker and the sample-end marker. Playback of the portion may be initiated by striking a drum-pad zone.
