Denoising real-time audio signals using matlab filter techniques
Abstract
In this paper,denoising of real time audio signals is carried out. Our main aim was toreduce the noise associated with the audiosignal. It is very important to reducenoise being present in any signalas it reduces its quality. For analysis purpose, white Gaussian noiseis concatenatedwith the audio signal and the resulting noisy signal is subjected to the different filtering techniques like Infinite Impulse Response (IIR) Filter, Finite Impulse Response (FIR) Filter, Wavelet transform techniques. A comparative analysis is carried out with different filters, in order to find the best filter suitable for denoising the audio signal.
