Provided are a memory device and waveform data editing method and editing program thereof. Waveform data obtained by sampling a musical sound is acquired, and a difference between a harmonic frequency of an n.sup.th harmonic of the waveform data and a resonance sound frequency of the n.sup.th harmonic sound of a resonance sound generation circuit is calculated, and if the difference is 1 Hz or more, a waveform of a frequency component of 20 Hz centered on a central of the frequency of the n.sup.th harmonic of a frequency spectrum is clipped. The difference calculated in regard to the clipped waveform is reduced. The waveform and the clipped original waveform are combined to edit the waveform data. Thus, in the waveform data, the difference between the harmonic frequencies of the resonance characteristic is eliminated, and resonance is facilitated and occurrence of beat of the sound is prevented.

A processor may store a first version of an audio file and fragment the audio file into at least a first time segment. The processor may receive a first edit to the audio file and identify a first edited version of the first time segment in the first edit. The processor may update the first version of the audio file with the first edit, resulting in a second version of the audio file comprising the first edited version of the first time segment. The processor may receive a second edit to the first version of the audio file and identify a second edited version of the first time segment in the second edit. The processor may determine, based on the second edited version, that the second edit alters an outdated version of the first time segment, resulting in an edit conflict. The processor may notify a user of the conflict.

A method generates first pitch data indicating a pitch of a first sound signal to be synthesized; and uses a generative model to estimate output data indicative of the first sound signal based on the generated first pitch data. The generative model has been trained to learn a relationship between second pitch data indicating a pitch of a second sound signal and the second sound signal. The first pitch data includes a first plurality of pieces of pitch notation data corresponding to pitch names, and is generated by setting, from among the first plurality of pieces of pitch notation data, a first piece of pitch notation data that corresponds to the pitch of the first sound signal as a hot value based on a difference between a reference pitch of a pitch name corresponding to the first piece of pitch notation data and the pitch of the first sound signal.

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 musical instrument according to one embodiment includes playing operators specifying respective pitches, and at least one processor which is configured to execute processing of acquiring string sound data including a fundamental sound component and a harmonic tone component corresponding to a specified pitch, acquiring stroke sound waveform data that does not include the fundamental sound component and the harmonic tone component corresponding to the specified pitch but includes components other than the fundamental sound component and the harmonic tone component, and synthesizing the string sound data and stroke sound data corresponding to the stroke sound waveform data at a set ratio.

Disclosed are a method for selecting background music and capturing a video, a device, a terminal apparatus, and a medium. The method includes: a music viewing instruction is acquired in a process of playing a video; a music detail corresponding to a background music fragment used by the video is displayed according to the music viewing instruction; a same-style capturing instruction is acquired, and a starting point of the background music fragment in a whole piece of music is acquired according to the same-style capturing instruction; a capturing instruction is acquired, and a video capturing is performed on a target scene according to the capturing instruction until a capturing stop instruction is acquired, and a corresponding video is acquired; and a corresponding music fragment is acquired, so the music fragment and the acquired video are synthesized to obtain a target video.

Provided are an audio file re-recording method and device, and a storage medium. The method includes: determining first time, the first time being start time of a recorded clip to be re-recorded in an audio file; playing a first recorded clip that has been recorded, the first recorded clip using the first time as end time in the audio file; upon arrival of the first time, collecting first voice data of a user to obtain a second recorded clip; and processing the first recorded clip and the second recorded clip to obtain a re-recorded audio file.
