Abstract: A controller includes a plurality of channel strips to which are allocated any one of a plurality of channels to be handled in a DAW. Each of the channel strips includes a channel strip display section, a movable fader capable of indicating a sound volume level of the allocated channel by means of a knob position of the fader, and a slide operation reception section operable to successively change the allocated channel. During a slide operation on the reception section, a CPU continuously updates only displayed content on the channel strip display section of each of the channel strips by a variation amount corresponding to the slide operation. Upon completion of the slide operation on the reception section, the CPU moves, through automatic control, the knob position of the movable fader of each of the channel strips.

Abstract: A method of analyzing audio signals, such as for a drive monitoring system, includes recording an audio signal from a mobile device, the audio signal including a background audio stream and a residual audio signal. Communication with an audio database is performed to obtain a reference signal. If a match between the background audio stream and the reference signal is determined, a time alignment between the background audio stream and the reference is computed. At least a portion of the recorded audio signal is aligned with the reference signal using the time alignment. The background audio stream is canceled from the recorded audio signal, to result in the residual audio stream. A computer processor is used to determine a driving behavior factor from the residual audio stream.

Abstract: Each of DAW processes and UI devices which are controllers of the DAW processes regularly sends a heartbeat signal including identification information of a music system which the DAW process or UI device belongs to, to a network by broadcast or multicast. The heart beat signal can be transmitted to the network using an Ethernet frame for UDP including the heartbeat signal in the data body, as a heartbeat packet. Based on the received heartbeat signal, it can be distinguished that the DAW process or UI device which sent the heartbeat signal is which of a device or music software process belonging to the relevant music system, a device or music software process belonging to another music system, and a device or music software process not belonging to any music system.

Abstract: Methods and systems for processing a sample of a media stream are provided. In one example, a method includes receiving a sample of a media stream rendered by a media rendering source, and for matching media recordings from which the sample was obtained, the method also includes receiving a signature file including a temporally mapped collection of features describing content of the matching media recordings. Each received signature file may be stored in memory. In addition, a signature stream may be received that includes features extracted from the media stream, and a number of matching features between the signature stream of the media stream and the signature file for at least one matching media recording can be determined. In one example, when substantially matching features between the signature stream of the media stream and the signature file for a matching media recording stop occurring, a discontinuity can be identified.

Abstract: An electronic device with one or more processors and memory detects a user input to play a media item, where the media item is associated with at least a portion of an audio track and one or more media files. The device requests the media item from a server in response to the user input and, in response to the request, receives, from the server, the one or more media files and information identifying at least the portion of the audio track. The device obtains at least the portion of the audio track based on the information identifying at least the portion of the audio track. The device also displays the one or more media files and, while displaying the one or more media files, plays back at least the portion of the audio track in synchronization with the one or more media files.

Abstract: Systems and methods audio matching using interest point overlap are disclosed herein. The systems include determining at least one matching reference segment based on a probe segment. Interest points for both the at least one matching reference segment and the probe segment can be generated. Probe segment interest points and matching reference segment interest points can be time aligned and frequency aligned. A count can be generated based on a number of overlapping interest points between each set of reference interest points and the set of probe segment interest points. The disclosed systems and methods allow false positive reference to be identified and eliminated based on the count. The benefits in eliminating false positive matches improve the accuracy of an audio matching system.

For each user, the server computer: receives a first audio signal fingerprint from a client device operated by a user, the first audio signal fingerprint associated with a first audio signal comprising ambient sound associated with the user and an audio signal of the program; searches the stored reference audio signal fingerprints to determine one that is related to the first audio signal fingerprint; determines an ambient sound signal by obtaining a difference between the stored reference audio signal fingerprint and the first audio signal fingerprint; and determines, using the ambient sound signal, an emotion of the user for a program segment. The server computer aggregates the emotions to determine a representative emotion of the users for the segment.

Abstract: Systems and methods for generating unique pitch-resistant descriptors for audio clips are provided. In one or more embodiments, a descriptor for an audio clip is generated as a function of relative magnitudes between interest points within the audio clip's time-frequency representation. A number of techniques for leveraging the relative magnitudes to generate descriptors are considered. These techniques include ordering of interest points as a function of ascending or descending magnitude, creation of binary vectors based on magnitude comparisons between pairs of points, and calculation of quantized magnitude ratios between pairs of points. Descriptors generated based on relative magnitudes according to the techniques disclosed herein are relatively invariant to common transformations to the original audio clip, such as pitch shifting, time stretching, global volume changes, equalization, and/or dynamic range compression.

Abstract: Sound alignment user interface techniques are described. In one or more implementations, a user interface is output having a first representation of sound data generated from a first sound signal and a second representation of sound data generated from a second sound signal. One or more inputs are received, via interaction with the user interface, that indicate that a first point in time in the first representation corresponds to a second point in time in the second representation. Aligned sound data is generated from the sound data from the first and second sound signals based at least in part on correspondence of the first point in time in the sound data generated from the first sound signal to the second point in time in the sound data generated from the second sound signal.
