Audiovisual performances, including vocal music, are captured and coordinated with those of other users in ways that create compelling user experiences. In some cases, the vocal performances of individual users are captured (together with performance synchronized video) on mobile devices, television-type display and/or set-top box equipment in the context of karaoke-style presentations of lyrics in correspondence with audible renderings of a backing track. Contributions of multiple vocalists are coordinated and mixed in a manner that selects for visually prominent presentation performance synchronized video of one or more of the contributors. Prominence of particular performance synchronized video may be based, at least in part, on computationally-defined audio features extracted from (or computed over) captured vocal audio. Over the course of a coordinated audiovisual performance timeline, these computationally-defined audio features are selective for performance synchronized video of one or more of the contributing vocalists.

Despite many practical limitations imposed by mobile device platforms and application execution environments, vocal musical performances may be captured and continuously pitch-corrected for mixing and rendering with backing tracks in ways that create compelling user experiences. Based on the techniques described herein, even mere amateurs are encouraged to share with friends and family or to collaborate and contribute vocal performances as part of virtual “glee clubs.” In some implementations, these interactions are facilitated through social network- and/or eMail-mediated sharing of performances and invitations to join in a group performance. Using uploaded vocals captured at clients such as a mobile device, a content server (or service) can mediate such virtual glee clubs by manipulating and mixing the uploaded vocal performances of multiple contributing vocalists.

In some examples, a system includes a first portable computing device that audibly renders a backing track, captures and pitch corrects a vocal performance of a first user, and transmits the first user's pitch corrected vocal performance. The system may also include a second portable computing device including a data communications interface that receives the first user's pitch corrected vocal performance, an audio transducer that audibly renders a mix of the backing track and the first user's pitch corrected vocal performance, a display for concurrent presentation of lyrics temporally synchronized with a vocal score and the backing track, a microphone interface that captures a vocal performance of a second user, and pitch correction code executable on the second portable computing device to pitch correct the second user's vocal performance in accord with the vocal score to produce a composite multi-vocal performance.
