System and method for producing a harmonious musical accompaniment

A method for enhancing audio comprising:

• receiving a first audio segment from a first interface;
• identifying a plurality of musical properties of the first audio segment including a first musical property associated with an identity of a chord and a second musical property associated with an identity of a key;
• calculating a subset of notes including at least one note from each of the plurality of musical properties that are substantially harmonious with the first audio segment based on the plurality of musical properties, the subset of notes including notes associated with the identified chord and including notes within the identified key;
• and
• selecting from the subset of notes towards exhibiting a degree of harmoniousness to generate an audio track to be played substantially synchronously with the first audio segment, wherein the degree of harmoniousness is based on a consonance metric.

An apparatus for enhancing audio comprising:

• a first interface to receive a first audio segment from a first source;
• and
• a harmonizing module coupled to the first interface, the harmonizing module configured to identify a plurality of musical properties of the first audio segment including a first musical property associated with an identity of a chord and a second musical property associated with an identity of a key, and wherein the harmonizing module is configured to calculate a subset of notes including at least one note from each of the plurality of musical properties that are substantially harmonious with the first audio segment based on the plurality of musical properties, the subset of notes including notes within the identified chord and including notes within the identified key;
• and
• a controller providing a control signal, wherein the harmonizing module is configured to select from the subset of notes based on the control signal and the degree of harmoniousness wherein the degree of harmoniousness is based on a consonance metric to generate an audio track to be played substantially synchronously with the first audio segment, wherein the audio track is generated by the harmonizing module substantially in real-time with the receipt of the first audio segment.

A method for enhancing audio comprising:

• receiving a first audio segment from a first interface;
• identifying a plurality of musical properties of the first audio segment including a first musical property associated with an identity of a chord and a second musical property associated with an identity of a key, wherein the identity of the key is identified by assigning a weight to each note in the first audio segment and determining the key based on the weights of each note of the first audio segment;
• calculate a subset of notes including at least one note from each of the plurality of musical properties that are substantially harmonious with the first audio segment based on the plurality of musical properties, the subset of notes including notes within the identified chord and including notes within the identified key;
• and
• selecting from the subset of notes based on a control signal and the degree of harmoniousness to generate an audio track to be played substantially synchronously with the first audio segment, wherein the degree of harmoniousness is based on a consonance metric and wherein the selection occurs substantially in real-time with the receipt of the first audio segment.

An apparatus for enhancing audio comprising:

• a first interface to receive a first audio segment from a first live source;
• a second interface to receive, substantially concurrent with the first audio segment, a second audio segment from a second live source;
• and
• a harmonizing module coupled to the first and second interfaces, the harmonizing module configured to identify a plurality of musical properties of the first audio segment including a first musical property associated with an identity of a chord and a second musical property associated with an identity of a key, and wherein the harmonizing module is configured to calculate a subset of notes including at least one note from each of the plurality of musical properties that are substantially harmonious with the first audio segment based on the plurality of musical properties, the subset of notes including notes within the identified chord and including notes within the identified key;
• and
• a controller providing a control signal, wherein the harmonizing module is configured to select one or more notes from the subset of notes of the first audio segment based on the control signal and the degree of harmoniousness, wherein the degree of harmoniousness is based on a consonance metric;
• and the harmonizing module configured to transform one or more notes in the second audio segment based on the one or more of the notes selected from the subset of notes in order to generate an audio track to be played substantially synchronously with the first audio segment.

A method for enhancing audio comprising:

• receiving a live first audio segment from a first interface;
• receiving, substantially concurrent with the first audio segment, a live second audio segment from a second interface;
• identifying a plurality of musical properties of the first audio segment including a first musical property associated with an identity of a chord and a second musical property associated with an identity of a key;
• calculating a subset of notes including at least one note from each of the plurality of musical properties that are substantially harmonious with the first audio segment based on the plurality of musical properties, the subset of notes including notes within the identified chord and including notes within the identified key;
• selecting one or more notes from the subset of notes towards exhibiting a degree of harmoniousness, wherein the degree of harmoniousness is based on a consonance metric;
• and
• transforming one or more notes in the second audio segment based on the one or more of the notes selected from the subset of notes in order to generate an audio track to be played substantially synchronously with the first audio segment.
