Subtracting noise from a received signal involves the risk of distorting the signal and if done improperly, it may lead to an increase in the noise level. This requires that the noise estimate ˆ n should be an exact replica of n. If it were possible to know theTutorial Lesson Video & Code: Lesson 1: Read Audio Files in Matlab. Lesson 2: Record Speech/Sound in Matlab. Lesson 3: Spectral Analysis of Speech Signal. Lesson 4: Framing, Windowing and Pre-Emphasis of Speech Signal. Lesson 5: Voice/Unvoiced/Silence analysis and Silence Removal from Speech.A local Fourier analysis is thus usefull to study the property of the sound such as its local amplitude and frequency. First we load a sound, with a slight sub-sampling. n = 1024*16; options.n = n; [x,fs] = load_sound('bird', n); Warning: WAVREAD will be removed in a future release. Use AUDIOREAD instead.

The sort of noise that I’m talking about is called “hiss,” and it’s much easier to explain with an example than with words. The following audio file is a recording of me reading the first two lines of “The Raven” by Edgar Allen Poe. A fundamental paper regarding applying Deep Learning to Noise suppression seems to have been written by Yong Xu in 2015. Yong proposed a regression method which learns to produce a ratio mask for every audio frequency. The produced ratio mask supposedly leaves human voice intact and deletes extraneous noise.I did in my original Answer. (I would now use an elliptic filter. The code is essentially the same, switching to the elliptic filter functions.) Frequency-selective filters are onoly useful for band-limited noise, and that can be determined by using the fft function.
