<p>The era of machine learning has opened up groundbreaking realities and opportunities in the field medical diagnosis. However, it is also observed that faster proper diagnosis any diseases/medical conditions require analysis classification digital signal data. It indicates identification tumors brain. Brain magnetic resonance imaging (MRI) data to be appropriately classified, similarly,...

In the context of content-based multimedia indexing gender identification using speech signal is an important task. Existing techniques are dependent on the quality of the speech signal making them unsuitable for the video indexing problems. In this paper we introduce a novel gender identification approach based on a general audio classifier. The audio classifier models the audio signal by the ...

In present stereo audio system is a most popular audio system for different purposes. Now a day’s stereo system is commonly used in communication and other purposes. Moreover Normalized Least Mean Square (NLMS) based adaptive filtering is an effective filtering process in case of communication and other applications. However adaptive filtering is an adaptive filter process to cancel out the noi...

Homomorphic signal processing techniques are used to place information imperceivably into audio data streams by the introduction of synthetic resonances in the form of closely spaced echoes These echoes can be used to place digital identi cation tags directly into an audio signal with minimal objectionable degradation of the original signal

Noise is often brought to host audio by common signal processing operation, and it usually changes the high-frequency component of an audio signal. So embedding watermark by adjusting low-frequency coefficient can improve the robustness of a watermark scheme. Moving Average sequence is a low-frequency feature of an audio signal. This work proposed a method which embedding watermark into the max...

Digital signal processing is being increasingly used for audio processing applications. Digital audio effects refer to all those algorithms that are used for enhancing sound in any of the steps of a processing chain of music production. Real time audio effects generation is a highly challenging task in the field of signal processing. Now a day, almost every high end multimedia audio device does...
