摘要： Diffuse or spatially large audio objects may be identified for special processing. A decorrelation process may be performed on audio signals corresponding to the large audio objects to produce decorrelated large audio object audio signals. These decorrelated large audio object audio signals may be associated with object locations, which may be stationary or time-varying locations. For example, the decorrelated large audio object audio signals may be rendered to virtual or actual speaker locations. The output of such a rendering process may be input to a scene simplification process. The decorrelation, associating and/or scene simplification processes may be performed prior to a process of encoding the audio data.

摘要： A first computing device is configured to establish a communication path with a second computing device and receive, from the second computing device over the communication path, an indication to begin transmitting an audio tone comprising identifying information for the first computing device, where the audio tone, when detected by the second computing device, causes the second computing device to update a user interface of the second computing device. Based on the received indication, the first computing device begins transmitting the audio tone. The second computing device is configured to detect, via at least one microphone, the audio tone and then, based on the detected audio tone, update the user interface.

摘要： A method implemented by a computing system comprises generating, by the computing system, a fingerprint comprising a plurality of bin samples associated with audio content. Each bin sample is specified within a frame of the fingerprint and is associated with one of a plurality of non-overlapping frequency ranges and a value indicative of a magnitude of energy associated with a corresponding frequency range. The computing system removes, from the fingerprint, a plurality of bin samples associated with a frequency sweep in the audio content.

摘要： Systems, methods, and devices are described herein for placing secondary content into a break of unknown duration in a stream of primary content. In one aspect, the described techniques may include streaming a segment of primary content, for example, by a reduce capability client device, such as a mobile device or tablet. The device may receive information indicative of a break in the streaming of the primary content. The device may play secondary content based on receiving the information indicative of the break. The device may determine when a next segment of the primary content is available, and begin streaming the next segment of the primary content upon detecting that the second segment of the primary content is available.

摘要： An adaptive echo cancellation system introduces an acoustic reference signal to audio content being transmitted to the speaker for playback. The acoustic reference signal is an out-of-band signal, such as an ultrasonic signal, which is typically not audible to humans. The microphone of the mobile device receives the audio content played back by the speaker as well as audio content introduced by the user (e.g., the speech of the user). The adaptive echo cancellation system detects the acoustic reference signal and determines a time delay between when the acoustic reference signal was introduced to the audio content and when the audio content including the acoustic reference signal was received by the mobile device. Echo is cancelled from the received audio content based on this determined time delay.

摘要： A computer device (100), configured to encode identifiers by providing audio identifiers therefrom, is described. The computer device (100) is configured to provide a set of audio signals as respective bitstreams. Each audio signal of the set of audio signals is defined based, at least in part, on audio signal information including at least one of a type, a fundamental frequency, a time signature and a time. Each audio signal comprises a set of audio segments. Each audio segment of the set of audio segments is defined based, at least in part, on audio segment information including at least one of a frequency, an amplitude, a transform, a time duration and an envelope. The computer device (100) is configured to receive an identifier and select a subset of audio signals from the set of audio signals according to the received identifier based, at least in part, on the audio signal information and/or the audio segment information. The computer device (100) is configured to process the audio selected subset of audio signals by combining the selected subset of audio signals to provide an audio identifier. The computer device (100) is configured to output the audio identifier in an output audio signal as an output bitstream, wherein the audio identifier encodes the identifier. Also described is a method of encoding identifiers by providing audio identifiers therefrom.

摘要： Methods, apparatus and articles of manufacture for research data gathering are disclosed. An example apparatus disclosed herein is to detect whether the apparatus is powered by an internal power source or an external power source. The example apparatus is also to, in response to detecting the apparatus is powered by the internal power source, perform first processing on a received audio signal to determine audio data to store in storage of the apparatus. The example apparatus is further to, in response to detecting the apparatus is powered by the external power source, perform second processing on the stored audio data to recover the code, the second processing different from the first processing.
