Audio Input and Audio Output - MATLAB & Simulink
https://www.mathworks.com/help/audio/gs/audio-input-and-audio-output.html
To read audio frame-by-frame into the workspace and then write audio frame-by-frame to your speakers, use the dsp.AudioFileReader and audioDeviceWriter functions. Create a dsp.AudioFileReader object to read audio from a file frame-by-frame. The audio file reader saves the sample rate of the audio file to the SampleRate property. fileReader = dsp.AudioFileReader …

Record Audio. Record data from an audio input device such as a microphone connected to your system: Create an audiorecorder object. Call the record or recordblocking method, where: record returns immediate control to the calling function or the command prompt even as recording proceeds. Specify the length of the recording in seconds, or end the ...

We import the audio signal into Matlab by executing the code below: % Program to implement a LPR (FIR) with cutoff 8kHz to denoise audio signal. [fileName, pathName] = uigetfile ('*.*', 'select the input audio'); [x, Fs] = audioread (num2str (fileName)); % x is the audio samples and Fs is the sampling rate.

audio - How to listen to the microphone in MATLAB? - …
https://stackoverflow.com/questions/39826838/how-to-listen-to-the-microphone-in-matlab
First of all, make sure to go to the microphone settings (input settings) and check the "listen to this microphone" checkbox. You should be hear your microphone input from your speakers because the following code will record computer's sound output. Since we are outputting your mic, you will be recording mic. Then you can record the sound output as:
Module 5: Record Audio Signals in MATLAB

Manipulating audio files in Matlab. Matlab’s standard installation comes with a set of audio files. The audio files,that can be considered as one-dimensional vectors, can be inspected and played using xpsound command. With this command, we can visualize the audio files in three ways Time series (data-vector as function of time)

We used MATLAB’s audio device reader to take audio input through the computer’s microphone. The audio is windowed into frames for analysis. We experimented with different window types to try to make the output reconstruction as seamless as possible; in the live implementation the output frames are added end to end

In this project we input a message from the user, say x(t). We take an audio signal (x(t)) on the input end and convolute it with another audio signal (y(t)). y(t) is the key audio signal. We convolve the two signals using a MATLAB code. After convolution, the original signal won’t be clear. This convoluted signal is f(t).
