Abstract
A method () and apparatus () for classifying a homogeneous audio segment are disclosed. The homogeneous audio comprises a sequence of audio samples (x(n)). The method () starts by forming a sequence of frames (-) along the sequence of audio samples (x(n)), each frame (-) comprising a plurality of the audio samples (x(n)). The homogeneous audio segment is next divided () into a plurality of audio clips (-), with each audio clip being associated with a plurality of the frames (-). The method () then extracts () at least one frame feature for each clip (-). A clip feature vector (f) is next extracted from frame features of frames associated with the audio clip (-). Finally the segment is classified based on a continuous function during the distribution of the clip feature vectors (f).
