Abstract: Systems and methods for identifying musical features in audio content are presented. Audio content information may be obtained from a digital audio file, the information providing a duration for playback of the audio content and a representation of sound frequencies associated with various moments throughout the duration of the audio content. Sound frequencies associated with one or more of the moments throughout the duration of the audio content may be identified, and characteristics or patterns of the identified sound frequencies may be recognized as being indicative of one or more musical features (e.g., parts, phrases, hits, bars, onbeats, beats, quavers, semiquavers, etc.). Some implementations of the present technology define display objects for display on a digital display, the display objects provided with visual features in an arrangement that distinguishes one musical feature from another across the duration of the audio content.

Abstract: Disclosed is a method for determining filter coefficients of an audio precompensation controller for the compensation of an associated sound system, including N?2 loudspeakers, including estimating, for each one of at least a pair of the loudspeakers, a model transfer function at each of M control points distributed in Z?2 spatially separated listening zones in a listening environment of the sound system. The method also includes determining, for each of the M control points, a zone-dependent target transfer function at least based on the zone affiliation of the control point; and determining the filter coefficients of the audio precompensation controller at least based on the model transfer functions and the target transfer functions of the M control points. Consequently, an audio precompensation controller for an associated sound system can be obtained that enables improved and/or customized sound reproduction in two or more listening zones simultaneously.

Abstract: A rotary fader apparatus includes a fader control knob that is directly attached to the rotor of a non-contact electrical motor. The apparatus may produce a fade effect based on the rotational position of the fader control knob and may be automated through signals to the motor. Such a rotary fader apparatus may be used, for example, in audio mixing applications to provide automated or manual rotary control of track fading. The motor may also be used to alter the feel of the movement of the fader control knob and/or provide tactile feedback in response to mixing parameters or signal properties.

Abstract: Described are techniques for determining whether a received audio signal is corrupted or a product of noise, prior to decoding the entire signal. A received audio signal may include both initialization data and encoded payload data. Correspondence between the initialization data and confirmation data may be determined. If the correspondence indicates a match, the audio receiver may continue decoding the audio signal to access the payload data. If the correspondence does not indicate a match, the audio receiver may cease decoding, which may conserve power, computing resources, and time, ensuring that subsequent audio signals are not missed while the audio receiver decodes a false or corrupted signal.

Abstract: Methods and systems described herein relate to management of media playback based on media preferences. A computing device may receive data indicating that a media item is available to be played by a media playback system. A media preference associated with the media item may then be identified based on the received data. The media preference may be identified in a preference database. Based on the media preference, the computing device determines whether the media item is or is not to be played by the media playback system. If a determination is made that the media item is not to be played, the computing device sends to the media playback system, an indication that the media item is not to be played. If a determination is made that the media item is to be played, the computing device causes the media item to be played by the media playback system.
