Separate 2 Channels in SoundInputRead.vi

[Y3G]

Hi ,

I would like to distinguish between 2 Channels that I am reading out from the SoundInputReadvi.

I can see that both are read but when I draw them using a graph, it seems that they are interpolated between each other.

The index in the picture should give me the Channel 1 or 2 in a seperate Array and then plot them on a graph.

I intentiinally put in channel1 a Sinus and in channel2 a Square wave same frequency. 

changing the index on in the loop did not distinguish between both Channels, it rather did an interpolation of both signals.

Any idea why

Thanks in advance

Hi YG3,

The waveform data you are receiving should be a 1D array of waveforms. Each element of the array should correspond to a channel. Perhaps if you put a waveform chart indicator immediately after the index array, that should give you the information you want. Hopefully this helps!
