Real-time DAQ and sound card visualization
Matlab code to read analog signal coming from a daq or from your sound card. This code allows to display the data in real-time or when the acquisition finished.
The real-time visualization method is better for monitoring.
The non real-time visualization method is better for accurate acquisitions.
It is an easy way to monitor or record your data coming from a daq or your sound card. I tried to write the simpler and the more general code possible. There is only one script file with a lot of comments to understand each step.
You can change many parameters like the duration, the number of channels or the type of daq easily.
The variable 'real_time_vis' can be changed to have a real time visualization of your data or not.
