    摘要： A chord detection apparatus retrieves musical performance data indicative of musical performance played by a user, retrieves musical piece information indicative of a musical piece played by the user, retrieves chord tendency information indicative of degrees of likelihood or unlikelihood of chords appearing in the musical piece, and detects a chord on the basis of the retrieved musical performance data and the retrieved chord tendency information.

    摘要： The present invention concerns a music audio representation method for analyzing a music audio signal (2) in order to extract a set of Chord Family Profiles (CFP) contained in the audio music signal (2), the method comprising the steps of: a) applying a first algorithm (4) to the music audio signal (2) in order to extract first data (5) representative of the tonality of music audio signal (2), and b) applying a second algorithm (6) to said first data (5) in order to provide second data (7) representative of the tonal centre contained in the first data (5).

    摘要： Enhancement of audio includes receiving a restriction parameter with audio input and determining a restricted audio input. Another audio input track is manipulated based on the restricted audio input track, and the audio tracks are combined. Conformation of audio to a musical key is also disclosed. The interval between two notes of the audio input are determined and a note corresponding to the second of the note is selected based on a musical key and the interval. Intervals between each note pair of the audio input are summed and each note is scored. A best-match note is selected. The second note of the audio input is conformed into the frequency of the best-match note. Creation of harmonizing tracks includes receiving audio input and harmonizing tracks are created. Each of the harmonizing tracks are transposed. Individual notes are manipulated based on a chord strictness threshold and audio output is provided.

    摘要： Two audio samples and/or sets of audio samples are identified. The pitch distributions of the audio samples and/or sets of audio samples are identified, the pitch distribution of an audio sample or set of audio samples referring to how much of each of multiple pitches of notes is present in the audio sample or set of audio samples. Based on the pitch distributions of the audio samples and/or sets of audio samples, at least one pitch of one of the audio sample and/or set of audio samples can be automatically adjusted (but need not be, depending on the pitch distributions) to increase harmonic coherence of the audio samples and/or sets of audio samples.

    摘要： A target set of one or more audio samples is automatically expanded to include one or more additional audio samples or sets of audio samples. Multiple different audio samples or sets of samples that have a high compatibility rating with the target set are identified. The high compatibility rating is based on rhythmic compatibility with the target set, harmonic compatibility with the target set, and/or compatibility with various other characteristics or parameters of the target set. One or more of the audio samples or sets of audio samples having a high compatibility rating with the target set are automatically added to the target set. Thus, the user is able to have a set of audio samples automatically added to a particular target set of audio samples, resulting in an expanded set of audio samples that sound coherent (e.g., rhythmically and harmonically compatible).

    摘要翻译： 一个或多个音频样本的目标集合被自动扩展以包括一个或多个附加音频样本或音频样本集合。 识别与目标集合具有高兼容性等级的多个不同音频样本或样本集合。 高兼容性等级基于与目标集的节律兼容性，与目标集合的谐波兼容性和/或与目标集合的各种其他特征或参数的兼容性。 具有与目标集合的高兼容性等级的一个或多个音频样本或音频样本集合被自动添加到目标集合中。 因此，用户能够将一组音频样本自动添加到特定的目标音频样本集合，从而产生声音相干（例如，有节奏和和谐地兼容）的扩展的音频样本集合。
