Abstract: Example embodiments relate to methods and systems for playback of adaptive music corresponding to an athletic activity. A user input is received from a user selecting an existing song for audible playback to the user, the song comprising a plurality of audio layers including at least a first layer, a second layer, and a third layer. Augmented playback of the existing song to the user is initiated by audibly providing the first layer but not the second layer. Physical activity information derived from a sensor corresponding to a real-time physical activity level of a user is received. If the physical activity level of the user is above a first activity level threshold, the augmented playback of the existing song is continued by audibly providing the first layer and the second layer to the user.

Abstract: A method, a system, and a computer program product detect a clipping event in audio signals. The method includes digitalizing audio signals having limited frequency bands, at a sampling frequency which is greater than two times as large as the maximum frequency component of the audio signal; and detecting a clipping event of the audio signals, based on magnitudes of spectrum in a bandwidth which is greater than or equal to the limited frequency band. The sampling frequency may be greater than or equal to three times as large as the maximum frequency component of the audio signal. The detection of a clipping event may include determining, for each frame, whether or not a sum or average of the magnitudes of spectrum at the bandwidth which is greater than or equal to the limited frequency band is larger than a predetermined threshold.

Abstract: Audio streams can be produced according to sequences of select content items. A first content item can be identified based on user input indicating tags associated with it. A second content item, and a content sequence for ordering the first content item and second item, are identified based on scores determined for various candidate content items. An audio stream is produced according to the content sequence and may then be transmitted to a client device for playback. The tags include metadata usable to selectively identify content items that can be combined to produce an optimal audio stream, such as based on the types of content items, the number of content items, the purpose of the content items to the audio stream, or more. Missing content items can be detected and signaled for production. An audio stream and content sequence therefor can be updated after initial production occurs.

Abstract: A gaming headset receives a plurality of audio channels comprising game audio channels and a chat audio channel during play of a particular game. The gaming headset monitors the received audio channels for predefined words that are associated with particular sounds in a data structure, and in response to detecting predefined words, filters out at least a portion of the detected predefined words from the received plurality of audio channels. The monitoring compares sounds on the received audio channels with the particular sounds in the data structure and also performs signal analysis on the audio channels during game play to detect the occurrence of the predefined words. The filtering mutes one or more of the plurality of audio channels so that the detected occurrence of the one of the predefined words is not output via speakers of the gaming headset.
