Audio classification method and system

摘要

Embodiments for audio classification are described. An audio classification system includes at least one device which executes a process of audio classification on an audio signal. The at least one device can operate in at least two modes requiring different resources. The audio classification system also includes a complexity controller which determines a combination and instructs the at least one device to operate according to the combination. For each of the at least one device, the combination specifies one of the modes of the device, and the resources requirement of the combination does not exceed maximum available resources. By controlling the modes, the audio classification system has improved scalability to an execution environment.

1. An audio classification system comprising:
at least one device operable in at least two modes requiring different resources; and a complexity controller which determines a combination of modes as a result of available resources, and instructs the at least one device to operate according to the combination of modes, wherein for each of the at least one device, the combination of modes specifies one of the modes of the device, where the resources requirement of the combination does not exceed maximum available resources, wherein the at least one device comprises the following: a pre-processor for adapting an audio signal to the audio classification system; a feature extractor for extracting audio features from segments of the audio signal; a classification device for classifying the segments with a trained model based on the extracted audio features; and a post processor for smoothing the audio types of the segments.
