Abstract: A recommendation of at least one of multiple audio samples or sets of audio samples to combine with a particular audio sample or set of audio samples is automatically generated. The recommendation is generated by determining the rhythmic compatibility as well as the harmonic compatibility of the particular audio sample or set of samples with each of the multiple audio samples or sets of audio samples. For each of the multiple audio samples or sets of audio samples, a compatibility rating is generated based on the rhythmic compatibility and the harmonic compatibility of the audio sample or set of audio samples with the particular audio sample or set of audio samples. At least one of the multiple audio samples or sets of audio samples is presented by a computing device as a recommendation to combine with the particular audio sample or set of audio samples.

Abstract: A user selects an audio sample to be combined with a set of audio samples. The selected sample is automatically combined with the set of samples based on metadata corresponding to the sample and metadata corresponding to the set of samples. The rhythmic content (beat locations) of the sample and/or set of samples is automatically adjusted to increase rhythmic coherence of the sample and the set of samples, and a pitch of the sample and/or set of samples is automatically adjusted to increase harmonic coherence of the sample and the set of samples. The user is thus able to select a sample and a set of samples, and have one or both automatically adjusted so that the combination sounds good together both rhythmically and harmonically. Audio samples can be similarly combined with other audio samples, and sets of audio samples can be similarly combined with other sets of audio samples.

Abstract: 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).

Abstract: 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.
