Real Time Special Effects Generation and Noise Filtration of Audio Signal Using Matlab Gui
نویسندگان
چکیده
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 digital signal processing in one form or another. For years musicians have used different techniques to give their music a unique sound. Earlier, these techniques were implemented after a lot of work and experimentation. However, now with the emergence of digital signal processing this task is simplified to a great extent. In this article, the generations of special effects like echo, flanging, reverberation, stereo, karaoke, noise filtering etc are successfully implemented using MATLAB and an attractive GUI has been designed for the same.

Modeling and Simulation of Substrate Noise in Mixed-Signal Circuits Applied to a Special VCO
The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...

Direction-of-arrival (DOA) estimation of audio signals is critical in different areas, including electronic war, sonar, etc. The beamforming methods like Minimum Variance Distortionless Response (MVDR), Delay-and-Sum (DAS), and subspace-based Multiple Signal Classification (MUSIC) are the most known DOA estimation techniques. The mentioned methods have high computational complexity. Hence using...
متن کاملReal Time Implementation of a Blind Beamformer for Subband Speech Enhancement Using Kurtosis Maximization
This paper presents a real time implementation of a blind beamformer for subband speech enhancement. The beamformer adaptively maximizes the statistical kurtosis measure of the beamformer’s output signal. Speech carries high kurtosis and noise often exhibit lower kurtosis. Hence, maximization of the output signal’s kurtosis enhances speech, in general. The implementation is carried out on a nov...

متن کاملDifferent Ways to Write Digital Audio Effects Programs
This paper is a very basic one, where one tries to explain how one can write a digital audio effect in a non-real time situation with a very general mathematical language such as MATLAB, and how such digital audio effects can be used in the real life. 1 What is a digital audio effect? The term « digital audio effects » has been used as an acronym for the COST action G6. So what is a digital aud...
