Computationally-assisted musical sequencing and/or composition techniques for social music challenge or competition

1. A social music method comprising:

capturing, using an audio interface of a portable computing device, a raw vocal performance by a user of the portable computing device;

in an audio processing pipeline,

computationally segmenting the raw captured vocal performance, wherein the segmenting results in a plurality of segments, and wherein each segment in the plurality satisfies a minimum segment length threshold such that a total number of segments in the plurality of segments is equal to or below a maximum number of segments;

temporally remapping segments of the segmented vocal performance; and

generating from the temporal remapping a derived musical composition;

audibly rendering the derived musical composition at the portable computing device; and

responsive to a selection by the user, causing a challenge to be transmitted to a remote second user, the challenge including an encoding of the derived musical composition and a seed including the user's raw captured vocal performance.

2. The method of claim 1 ,

wherein the seed encodes the segmentation of the user's captured vocal performance.

3. The method of claim 1 , further comprising:

receiving, for a vocal contribution of the remote second user captured in response to the challenge, a segmentation of the remote second user's vocal contribution; and

from a combined segment set including at least some vocal segments captured from the user and at least some vocal segments captured from the remote second user, temporally remapping segments of the combined segment set and generating therefrom a derived musical composition including contributions of both the user and the remote second user.

4. The method of claim 3 , wherein temporally remapping segments of the combined segment set and generating therefrom a derived musical composition including contributions of both the user and the remote second user utilizes fairness logic to ensure a level of balance in the derived musical composition amongst the contributions of the user and the remote second user.

5. The method of claim 1 , further comprising:

receiving a vocal contribution of the remote second user captured in response to the challenge; and

from a combined audio signal including at least some portions of the captured vocal performance of the user and at least some portions of the captured vocal contribution of the remote second user,

computationally segmenting the combined audio signal;

temporally remapping the segments of the combined audio signal; and

generating from the temporally remapped segments a derived musical composition including vocal content from both the user and the remote second user; and

audibly rendering the derived musical composition at the portable computing device.

6. The method of claim 1 ,

wherein the audio processing pipeline is implemented on the portable computing device.

7. The method of claim 1 ,

wherein the audio processing pipeline is implemented, at least in part, on a service platform in data communication with the portable computing device.

8. A computer program product encoded in one or more non-transitory computer-readable media, the computer program product including instructions executable on a processor of the portable computing device to cause the portable computing device to perform or initiate the steps recited in claim 1 .

9. A system comprising the portable computing device programmed with instructions executable on a processor thereof to cause the portable computing device to perform or initiate the steps recited in claim 1 .

10. An audio processing pipeline implemented on a portable computing device comprising:

a segmentation stage for computationally segmenting at least a current vocal contribution captured in connection with a vocal performance battle, wherein the computational segmenting results in a plurality of segments, and wherein each segment in the plurality satisfies a minimum segment length threshold such that a total number of segments in the plurality of segments is equal to or below a maximum number of segments;

a partition mapping stage for temporally remapping segments from a combined segment set including at least some vocal segments captured from an initial user's seed performance and at least some vocal segments from one or more subsequent vocal contributors, including the current vocal contribution, captured in connection with the vocal performance battle, the initial user's seed performance including a raw captured vocal performance of the initial user; and

further stages for generating from the temporal remapping, a derived musical composition including contributions of the initial user and one or more of the subsequent vocal contributors and for rendering the derived musical composition as an audio signal.

11. The audio processing pipeline of claim 10 ,

wherein segmentations of a seed performance and of subsequent vocal contributions are introduced into the audio processing pipeline at, or before, the partition mapping stage for subsequent round audio processing.

12. The audio processing pipeline of claim 10 , wherein the stages for generating from the temporal remapping a derived musical composition including contributions of the initial user and one or more of the subsequent vocal contributors utilizes fairness logic to ensure a level of balance in the derived musical composition amongst the contributions of the initial user and the subsequent vocal contributors.
