Systems, devices and methods are provided to automatically identify advertisements or other portions of a broadcast television stream before the stream is distributed via a cable, DBS, IPTV or other medium. The television broadcast is received at the data processing system, and audio content of the television broadcast is analyzed to generate an audio fingerprint of a portion of the audio content. The identified audio fingerprint are compared to audio fingerprints stored in a database to thereby identify the portion of the television broadcast based on the generated audio fingerprint. By identifying the contents of an actual broadcast prior to redistribution of the broadcast, additional actions may be taken that are unique to the identified content.

A mobile device responds in real time to media content presented on a media device, such as a television. The mobile device captures temporal fragments of audio-video content on its microphone, camera, or both and generates corresponding audio-video query fingerprints. The query fingerprints are transmitted to a search server located remotely or used with a search function on the mobile device for content search and identification. Audio features are extracted and audio signal global onset detection is used for input audio frame alignment. Additional audio feature signatures are generated from local audio frame onsets, audio frame frequency domain entropy, and maximum change in the spectral coefficients. Video frames are analyzed to find a television screen in the frames, and a detected active television quadrilateral is used to generate video fingerprints to be combined with audio fingerprints for more reliable content identification.

A smart phone application is configured to connect to the internal microphone to continuously monitor ambient audio picked up by the microphone by keeping the microphone always on in order to detect the presence of music. When a song is detected by audio analysis an acoustic fingerprint is created and compared against a song database of acoustic fingerprints. When the artist and title of a song is obtained by the smart phone application, the application stores that information in a listing.

In one embodiment, a diagnostics system is provided. The diagnostics system include a detection system configured to capture acoustic information and contextual information related to a machine component defect. A computing system is coupled to a processor configured to receive the acoustic information and the contextual information from the detection system, select one or more algorithms based at least in part on the contextual information, and retrieve and execute the one or more algorithms to extract one or more characteristic features of the acoustic information. The processor is further configured to generate an acoustic fingerprint based at least in part on the one or more characteristic features of the acoustic information, such that the one or more characteristic features correspond to the machine component defect.

The tire (14) includes a tread shaped such that, beyond a predetermined radial wear threshold, the tread includes an assembly of at least one wear indicator including a so-called "sound" cavity (120A, 120B, 121) arranged in a circumferential groove of the tread. During the monitoring process, an acoustic signal above a predetermined threshold is detected (100) by an acoustic sensor (20) onboard the vehicle (12), said signal being capable of including an acoustic fingerprint noise produced by the assembly of at least one wear indicator (120A, 120B, 121) while the tire (14) runs on the ground, and information relating to the acoustic signal is transmitted (308) to a remote server (30) that is not onboard the vehicle (12).

An audio fingerprint is extracted from an audio sample, where the fingerprint contains information that is characteristic of the content in the sample. The fingerprint may be generated by computing an energy spectrum for the audio sample, resampling the energy spectrum, transforming the resampled energy spectrum to produce a series of feature vectors, and computing the fingerprint using differential coding of the feature vectors. The generated fingerprint can be compared to a set of reference fingerprints in a database to identify the original audio content.
