Constrained dynamic amplitude panning in collaborative sound systems

摘要

In general, techniques are described for performing constrained dynamic amplitude panning in collaborative sound systems. A headend device comprising one or more processors may perform the techniques. The processors may be configured to identify, for a mobile device participating in a collaborative surround sound system, a specified location of a virtual speaker of the collaborative surround sound system and determine a constraint that impacts playback of audio signals rendered from an audio source by the mobile device. The processors may be further configure to perform dynamic spatial rendering of the audio source with the determined constraint to render audio signals that reduces the impact of the determined constraint during playback of the audio signals by the mobile device.

1. A method comprising:
identifying two or more mobile devices of a plurality of mobile devices participating in a collaborative surround sound system capable of representing a virtual speaker of the collaborative surround sound system; determining a constraint that impacts playback of audio signals rendered from audio source data by at least one of the identified two or more mobile devices; determining, based on the constraint, a gain for the at least one of the identified two or more mobile devices; and rendering the audio source data using the gain to generate audio signals that reduce the impact of the determined constraint during playback of the audio signals by the identified two or more mobile devices.
