    Abstract: In general, techniques are described for forming a collaborative sound system. A headend device comprising one or more processors may perform the techniques. The processors may be configured to identify mobile devices that each includes a speaker and that are available to participate in a collaborative surround sound system. The processors may configure the collaborative surround sound system to utilize the speaker of each of the mobile devices as one or more virtual speakers of this system and then render audio signals from an audio source such that when the audio signals are played by the speakers of the mobile devices the audio playback of the audio signals appears to originate from the one or more virtual speakers of the collaborative surround sound system. The processors may then transmit the processed audio signals rendered to the mobile device participating in the collaborative surround sound system.

    Abstract: 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.

    Abstract: Apparatus and methods for audio noise attenuation are disclosed. An audio signal analyzer can determine whether an input audio signal received from a microphone device includes a noise signal having identifiable content. If there is a noise signal having identifiable content, a content source is accessed to obtain a copy of the noise signal. An audio canceller can generate a processed audio signal, having an attenuated noise signal, based on comparing the copy of the noise signal to the input audio signal. Additionally or alternatively, data may be communicated on a communication channel to a separate media device to receive at least a portion of the copy of the noise signal from the separate media device, or to receive content-identification data corresponding to the content source.

    Abstract: A device includes a memory configured to store untransformed ambisonic coefficients at different time segments. The device also includes one or more processors configured to obtain the untransformed ambisonic coefficients at the different time segments, where the untransformed ambisonic coefficients at the different time segments represent a soundfield at the different time segments. The one or more processors are also configured to apply one adaptive network, based on a constraint, to the untransformed ambisonic coefficients at the different time segments to generate transformed ambisonic coefficients at the different time segments, wherein the transformed ambisonic coefficients at the different time segments represent a modified soundfield at the different time segments, that was modified based on the constraint.
