Simple Audio (2 CH) in and modulation NOT WORKING

[johndoeNOTdaniel]

Hello everyone!

I am new to LABVIEW especially NI myDAQ.

What I am trying to do is to combine signal from my audio source and artificially generated signal

within the Labview.. I tried many different ways.. but it does not seem to work.

Project 1 is the one that I just take signal and send it out after some filter.

Project 2, I tried to combine (add or multiply) sine way to shift the tone of my audio input go high/low.

Can anyone please help me how to do this?

Hey,

The simulate signal VI is going to generate N samples of a given waveform each time it is called (where N is a user specified value).  Similarly the DAQ Assistant can be configured to return N samples from the Analog input each time it is called.  The easiest way to combine these signals is simply to put both express VIS (the DAQ Assistant and the Simulate Signal) in the same loop configured with the same number of samples and simple add / multiply / subtract the two variant data types they output.

Does that work for what you're trying to accomplish?  Let us know if you have more specific questions about this.

Thanks!
