This paper deals with the modifications of the audio signal in a parametric audio coder at the decoder stage. The parametric audio coder is based on the application of adaptive signal models for each audio signal component. These adaptive signal models are obtained by using different approaches so as to extract a multi-part model from the audio signal. The audio signal is supposed to be constit...

Among the basic elements of music, timbre is one most important sound, and it also main basis for distinguishing pronunciation from another. People usually have ability to “listen argue” because everyone’s different. However, existing audio extraction technology has low efficiency accuracy. Therefore, this paper aims discuss algorithm that can make music feature more accurate efficient. For sig...

Audio signal classification system analyzes the input audio signal and creates a label that describes the signal at the output. These are used to characterize both music and speech signals. The categorization can be done on the basis of pitch, music content, music tempo and rhythm. The signal classifier analyzes the content of the audio format thereby extracting information about the content fr...
