First load the signal into MATLAB using the command wavread (using older MATLAB versions) and audioread (using newer versions) which you can read more about in the MATLAB help file. Example of loading audio file and playing audio in MATLAB (2017a): a.) Use the DFT to figure out the tone frequencies (at least approximately).

I am trying to process an audio file in Matlab by filtering out all frequencies except those within $\pm 25\ Hz$ of $523\ Hz$ (as well as its harmonics up to the Nyquist). The resulting waveform should look like the green wave displayed below (blue being the original): However, my resulting waveform is entirely zero: Here is the simple code I ...

I'm trying to apply a filter to an audio signal in MATLAB and having some trouble processing it. So far, I have a transfer function that describes a K-weighted filter, and I am able to create a bode plot that looks correct. Here is the script for that one: I have another script that reads audio from a .wav file, plays it, and plots the waveform.

Matlab is a good tool for the analysis of an audio signal. It has functions that make it much easier to visualize these signals. Just as discussed, audio signal analysis requires a proper tool to deal with in which Matlab is. Filtering audio signal is an important feature since it can be used to retain lost information.

How to filtre an audio signal with low-pass filtre

Butterworth filters can be designed with high rolloffs, but they require long filters and can have stability problems. Chebyshev filters are better for low-frequency applications because they have steep rolloffs and can be designed to eliminate baseline wander and d-c offsets in signals with significant low frequency content (such as EKGs).

As such, we can apply a bandpass filter to get rid of the low noise, capture most of the voice, and any noisy frequencies on the higher side will get cancelled as well. Here are the steps that I did: Read in the audio file using audioread. ... Browse other questions tagged matlab audio signal-processing wav noise-reduction or ask your own question.
