TLDR
In this paper, a system that performs analysis and comparison of audio data files based upon the content of the data files is presented, which produces a set of numeric values (a feature vector) that can be used to classify and rank the similarity between individual audio files typically stored in a multimedia database or on the Web.Abstract:
A system that performs analysis and comparison of audio data files based upon the content of the data files is presented. The analysis of the audio data produces a set of numeric values (a feature vector) that can be used to classify and rank the similarity between individual audio files typically stored in a multimedia database or on the World Wide Web. The analysis also facilitates the description of user-defined classes of audio files, based on an analysis of a set of audio files that are members of a user-defined class. The system can find sounds within a longer sound, allowing an audio recording to be automatically segmented into a series of shorter audio segments.read more

Intelligent electronic appliance system and method
TL;DR: In this paper, a set top box for interacting with broadband media streams, with an adaptive user interface, content-based media processing and/or media metadata processing, and telecommunications integration, is presented.
Proceedings Article
Mel frequency cepstral coefficients for music modeling
TL;DR: The results show that the use of the Mel scale for modeling music is at least not harmful for this problem, although further experimentation is needed to verify that this is the optimal scale in the general case and whether this transform is valid for music spectra.
Patent
Adaptive pattern recognition based control system and method
TL;DR: An adaptive interface for a programmable system, for predicting a desired user function, based on user history, as well as machine internal status and context, is presented for confirmation by the user, and the predictive mechanism is updated based on this feedback as mentioned in this paper.
Patent
Intuitive computing methods and systems
TL;DR: A smart phone senses audio, imagery, and/or other stimulus from a user's environment, and acts autonomously to fulfill inferred or anticipated user desires as discussed by the authors, and can apply more or less resources to an image processing task depending on how successfully the task is proceeding or based on the user's apparent interest in the task.
Patent
Connected audio and other media objects
TL;DR: In this paper, a decoding process extracts the identifier from a media object and possibly additional context information and forwards it to a server, in turn, maps the identifier to an action, such as returning metadata, re-directing the request to one or more other servers, requesting information from another server to identify the media object, etc.
