Wireless handheld audio capture device and multi-vocalist method for audiovisual media application
Embodiments described herein relate generally to systems comprising a display device, a display device-coupled computing platform, a mobile device in communication with the computing platform, and a content server in which methods and techniques of capture and/or processing of audiovisual performances are described and, in particular, description of techniques suitable for use in connection with display device connected computing platforms for rendering vocal performance captured by a handheld computing device.
1. A method comprising:
establishing short-range wireless communications between a portable computing device and a display device-coupled computing platform, the display device-coupled computing platform in communication with a separate content server;
using the portable computing device in a generally upside-down orientation as a wirelessly coupled audio capture interface for the display device-coupled computing platform while the display device-coupled computing platform provides pitch cues and an audibly rendered backing track in temporal correspondence with the pitch cues;
capturing, via a microphone of the portable computing device, vocal audio from the user of the portable computing device;
capturing, via a first camera of another device separate from the portable computing device, a first user video synchronized with the captured vocal audio; and
visually rendering, on the other device, a sequence of visual layouts including the pitch cues and lyrics in temporal correspondence with the audibly rendered backing track, a first visual cell displaying the first user video synchronized with the captured vocal audio, and a second visual cell displaying a second user video synchronized with the captured vocal audio, wherein successive visual layouts of the sequence of visual layouts each include the first and second visual cells, and wherein a visual arrangement and sizing of the first and second visual cells, including respective ones of the first and second user videos displayed in the first and second visual cells, varies in correspondence with structural information, including a predefined sequence of vocal parts of a performance score, associated with the audibly rendered backing track.
2. The method of claim 1 ,
wherein the other device includes a display device of the display device-coupled computing platform.
3. The method of claim 1 , further comprising:
displaying, while the portable computing device is in a generally right-side-up orientation, first display content including an indication to reorient the portable computing device; and
responsive to detection of a change in orientation of the portable computing device, displaying in the generally upside-down orientation, second display content including one or more user interface controls for audio capture.
4. The method of claim 1 , further comprising:
visually rendering, on a touchscreen display of the portable computing device, cues corresponding to an amplitude of the captured vocal audio.
5. The method of claim 1 , further comprising:
pitch correcting the captured vocal audio in real-time, wherein the pitch correcting the captured vocal audio in real-time is performed by one or both of the portable computing device and the display device-coupled computing platform.
6. The method of claim 1 , further comprising:
pitch correcting the captured vocal audio in real-time; and
audibly rendering, at the display device-coupled computing platform, the pitch-corrected vocal audio.
7. The method of claim 1 , further comprising:
capturing, via a second camera of a remote portable computing device, the second user video synchronized with the captured vocal audio.
8. The method of claim 1 , further comprising:
detecting, using one or more of an accelerometer and a gyroscope of the portable computing device, an orientation of the portable computing device different than the generally upside-down orientation, and in response to the detected different orientation, using the portable computing device to provide corrective feedback to the user.
9. A computer program product including non-transitory media encoding instructions executable to perform the method of claim 1 .
10. The method of claim 1 , further comprising:
transmitting, to the separate content server, the captured vocal audio and the first user video for mixing with other audiovisual content from other sources, including the second user video captured by the second camera of the remote portable computing device, to visually render the sequence of visual layouts.
