Continuous score-coded pitch correction

摘要

Vocal musical performances may be captured and continuously pitch-corrected at a mobile device for mixing and rendering with backing tracks in ways that create compelling user experiences. In some cases, the vocal performances of individual users are captured in the context of a karaoke-style presentation of lyrics in correspondence with audible renderings of a backing track. Such performances can be pitch-corrected in real-time at the mobile device in accord with pitch correction settings. In some cases, such pitch correction settings code a particular key or scale for the vocal performance or for portions thereof. In some cases, pitch correction settings include a score-coded melody sequence of note targets supplied with, or for association with, the lyrics and/or backing track. In some cases, pitch correction settings are dynamically variable based on gestures captured at a user interface.

主权项

1. A method comprising:
using a portable computing device for vocal performance capture, the portable computing device having a display, a microphone interface and a data communications interface; retrieving via the data communications interface both (i) lyrics and (ii) pitch correction settings, the retrieved lyrics and pitch correction settings respectively coding temporal correspondence of particular lyrics and of particular variations in pitch correction settings with particular points in a backing track; at the portable computing device, audibly rendering a first encoding of the backing track and concurrently presenting the lyrics on the display in accord with the temporal correspondence coding thereof; at the portable computing device, capturing and continuously pitch correcting a vocal performance of a user in accord with the coded temporal variations in pitch correction settings; mixing the pitch-corrected vocal performance into the audible rendering of the backing track at the portable computing device, wherein the resulting mixed performance includes the user's own vocal performance captured in correspondence with the lyrics and backing track, but pitch-corrected in accord with the coded temporal variations in pitch correction settings; transmitting from the portable computing device to a remote device via the data communications interface, an audio encoding of the pitch-corrected vocal performance; and varying the pitch correction settings dynamically during the vocal performance capture in correspondence with user interface gestures by the user.
