Why: To demonstrate that you can use MATLAB and your laptop to develop and test real time audio signal processing algorithms Who: – I manage a development group at MathWorks focused on DSP and Communications Includes fixed-point modeling and deployment to C or HDL – Audio is a focus area for DSP System Toolbox What:
Audio Input and Output - MATLAB & Simulink
https://www.mathworks.com/help/daq/audio-input-and-output.html
Data Acquisition Toolbox does not read directly from or write directly to audio files using the multichannel audio feature. Instead, use the MATLAB functions audioread and audiowrite. Multichannel Audio Scan Rate. The Rate of an audio DataAcquisition is the scan rate at which it samples audio data. All channels in a DataAcquisition have the ...

Generate audio signals (Handel's "Hallelujah Chorus"). "Hallelujah" should be voiced five times, one for each segment depicted in the figure on all channels of the speaker system.
Signal Acquisition - MATLAB & Simulink
https://www.mathworks.com/matlabcentral/answers/1837-signal-acquisition
Signal Acquisition. I want to acquire and visualize EEG signals using Matlab. We have our own custom signal acquisition system (electrodes, filters and amplifiers). But, we cannot figure out a way to get the sensed signals onto the computer (MATLAB).
Using MATLAB and Arduino to Acquire Analog Signals - …
https://www.mathworks.com/videos/using-matlab-and-arduino-to-acquire-analog-signals-100739.html
Let us go to MATLAB command window and see if we can measure the analog signal using this function. I repeated the function a few times to make sure that I'm reading the stabilized voltage from the sensor. Now, the next task is to convert this value of voltage to temperature. For this, I'm going to explain when you can use a function in MATLAB.

Create an Echometer Using Audio Measurements. This example shows how to create an echometer sonar using audio data acquisition and signal processing, which can measure distance by determining the time of flight of a sound pulse reflected off of a surface. This example employs an approach for post synchronization of audio output and input data ...
