Abstract: A handle assembly for an electronic device, such as an audio device, is described herein. In some implementations, the handle assembly includes a flexible fabric, rope handle that attaches at the side and near the top of the device. The attachment assembly utilizes an eyelet that slides onto the rope handle prior to attaching an endpiece to the rope. The endpiece is inserted into a device housing opening that receives the handle attachment assembly. The eyelet is then inserted into that housing opening to secure the eyelet and endpiece into the opening. A sealing member, such as an O-ring, is utilized to secure the eyelet into the opening, and to provide other benefits, such as preventing or reducing acoustic buzz that would otherwise occur between the eyelet and the casing during audio playback.

Abstract: In general, techniques are described by which to provide priority information for higher order ambisonic (HOA) audio data. A device comprising a memory and a processor may perform the techniques. The memory stores HOA coefficients of the HOA audio data, the HOA coefficients representative of a soundfield. The processor may decompose the HOA coefficients into a sound component and a corresponding spatial component, the corresponding spatial component defining shape, width, and directions of the sound component, and the corresponding spatial component defined in a spherical harmonic domain. The processor may also determine, based on one or more of the sound component and the corresponding spatial component, priority information indicative of a priority of the sound component relative to other sound components of the soundfield, and specify, in a data object representative of a compressed version of the HOA audio data, the sound component and the priority information.

Furthermore, for every frequency band in the microphone pair, a single sound source mask indicating whether or not a component of the frequency band is a single sound source is calculated. Then, the calculated inter-microphone phase difference and the calculated single sound source mask are input as feature quantities to a multi-label classifier, and a direction label associated with a sound source direction is output to the feature quantities.
