Continuous Pitch-Corrected Vocal Capture Device Cooperative with Content Server for Backing Track Mix

摘要

Techniques have been developed to facilitate (1) the capture and pitch correction of vocal performances on handheld or other portable computing devices and (2) the mixing of such pitch-corrected vocal performances with backing tracks for audible rendering on targets that include such portable computing devices and as well as desktops, workstations, gaming stations, even telephony targets. Implementations of the described techniques employ signal processing techniques and allocations of system functionality that are suitable given the generally limited capabilities of such handheld or portable computing devices and that facilitate efficient encoding and communication of the pitch-corrected vocal performances (or precursors or derivatives thereof) via wireless and/or wired bandwidth-limited networks for rendering on portable computing devices or other targets.

主权项

1. A method comprising:
using a portable computing device for vocal performance capture, the handheld computing device having a display, a microphone interface and a data communications interface; responsive to user selection of a backing track, retrieving via the data communications interface at least lyrics and timing information corresponding to the backing track; at the portable computing device, audibly rendering a first encoding of the backing track and concurrently presenting the retrieved lyrics on the display in accord with the timing information; at the portable computing device, capturing and pitch correcting a vocal performance of the user in accord with pitch correction settings; and transmitting from the portable computing device to a remote server via the communications interface, an audio encoding of the pitch-corrected vocal performance for mixing with a second encoding of the backing track.
