    Abstract: A system and method may be configured to analyze audio information derived from an audio signal. The system and method may track sound pitch across the audio signal. The tracking of pitch across the audio signal may take into account change in pitch by determining at individual time sample windows in the signal duration an estimated pitch and a representation of harmonic envelope at the estimated pitch. The estimated pitch and the representation of harmonic envelope may then be implemented to determine an estimated pitch for another time sample window in the signal duration with an enhanced accuracy and/or precision.

    Abstract: A system and method may be provided to segment and/or classify an audio signal from transformed audio information. Transformed audio information representing a sound may be obtained. The transformed audio information may specify magnitude of a coefficient related to energy amplitude as a function of frequency for the audio signal and time. Features associated with the audio signal may be obtained from the transformed audio information. Individual ones of the features may be associated with a feature score relative to a predetermined speaker model. An aggregate score may be obtained based on the feature scores according to a weighting scheme. The weighting scheme may be associated with a noise and/or SNR estimation. The aggregate score may be used for segmentation to identify portions of the audio signal containing speech of one or more different speakers. For classification, the aggregate score may be used to determine a likely speaker model to identify a source of the sound in the audio signal.

    Abstract: A method for constructing a metal wire with embedded filaments or cavities therein for biomedical applications. The method includes first drilling nonconcentric apertures in a symmetrical pattern in a metal rod and then embedding filaments in the apertures. The metal rod is then drawn and thermally-treated to form a metal wire with embedded filaments therein. The filaments may advantageously provide fatigue resistance, radiopacity, and electrical conductance to the metal wire. The method optionally provides an additional step for withdrawing or removing the filaments using various methods to create cavities for cavity access within the metal wire. The metal wire may be finished to provide access to the cavities or filaments embedded therein. The cavities may then be filled with a therapeutic drug for elution inside the human body or used for passage of body fluids. An optional biocompatible coating may be disposed around the metal wire to prevent escape of the therapeutic drug before insertion into the human body. The cavities may also be filled with different materials as compared to the original filaments.
