Coordinating and mixing vocals captured from geographically distributed performers

摘要

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.

主权项

1. A method of preparing coordinated vocal performances for a geographically distributed glee club, the method comprising:
receiving via a communication network, a first audio encoding of first performer vocals captured at a first remote device; mixing the first performer vocals with a backing track and supplying a second remote device with a resulting first mixed performance; receiving via the communication network, a second audio encoding of second performer vocals captured at the second remote device against a local audio rendering of the first mixed performance; and supplying the first and second remote devices with corresponding combined performance mixes of the captured first and second performer vocals with the backing track, wherein the combined performance mix supplied to the first remote device features one of the first and second performers more prominently than the other, and wherein the combined performance mix supplied to the second remote device features more prominently the other of the first and second performers.
