    摘要: The subject disclosure is directed towards dynamically computing anti-aliasing filter coefficients for sample rate conversion in digital audio. In one aspect, for each input-to-output sampling rate ratio (pitch) obtained, anti-aliasing filter coefficients are interpolated based upon the pitch (e.g., using the fractional part of the ratio) from two filters (coefficient sets) selected based upon the pitch (e.g., using the integer part of the ratio). The interpolation provides for fine-grained cutoff frequencies, and by re-computation for each pitch, smooth anti-aliasing with dynamically changing ratios.

    摘要: A method of operating an audio monitoring system includes generating with a sound sensor audio data corresponding to a sound event generated by an object in a scene around the sound sensor, identifying with a processor a type and action of the object in the scene that generated the sound with reference to the audio data, generating with the processor a timestamp corresponding to a time of the detection of the sound event, and updating a scene state model corresponding to sound events generated by a plurality of objects in the scene with reference to the identified type of object, action taken by the object, and the timestamp. The method further includes identifying a sound event in the scene with reference to the scene state model and a predetermined scene grammar stored in a memory, and generating with the processor an output corresponding to the sound event.

    摘要: An interesting section extracting device extracts an interesting section of interest to a user from a video file with reference to an audio signal included in the video file such that a specified time is included in the interesting section. The interesting section extracting device includes an interface device that obtains the specified time; and a likelihood vector generating unit that calculates, in one-to-one correspondence with first unit sections of the audio signal, likelihoods for anchor models that respectively represent features of a plurality of types of sound pieces and generates likelihood vectors having the calculated likelihoods as components thereof. An interesting section extracting unit calculates a first feature section as candidate section, which is candidate for the interesting section to be extracted, by using likelihood vectors and extract, as the interesting section, part of the first feature section including the specified time.

    摘要: A method for testing an audio player device is provided. The method includes: transcribing sound signals of each of the audio files which are supposed to be supported by the audio player device as a sound file; determining the ID code of each of the sound files; and determining whether the ID code of each of the sound files has been listed on a predetermined audio format table by comparing the ID code of each of the sound files with the ID codes listed on the audio format table, thus to determine which of audio formats listed on the audio format table is supported by the audio player device according to the relationships of the ID codes and the audio formats recorded by the audio format table. A test device applying the method to testing audio player devices is also provided.
