Abstract
A method and an information processing apparatus to generate a digital score file of a song are described. The information processing apparatus includes processing circuitry. The processing circuitry is configured to obtain a candidate audio file satisfying a first condition from audio files of unaccompanied singing of the song without instrumental accompaniment. The processing circuitry is configured to divide the candidate audio file into valid audio segments based on timing information of the song, and extract pieces of music note information from the valid audio segments. Each of the pieces of music note information includes at least one data set of a music note in the song. The data set includes an onset time, a duration, and a music note value of the music note. The processing circuitry is configured to generate the digital score file based on the pieces of music note information.
