Hello Labview Community,
i would like to make simple VI for the cRIO-9076 modules NI9234 and NI9263, which outputs an MLS signal, records the sound signal and then determines the impulse response using a cross-correlation.
In the attached LabVIEW VI this is easily implemented with the Sound Output VI and the Sound Input VI in LabVIEW Version 18.
Now I want to implement exactly the same output and input of the signal with the cRIO-9076 and the plugged-in modules NI9234 for microphone analog input and NI9263 for loudspeaker analog output (just replace the usb mikrofon and loudspeaker from Sound Input and Output Express VI)
Is there a simple way to implement this (with a time-controlled loop structure) in LabVIEW without FPGA, so that my sampling rate still remains 44100 Hz and the recording time of the microphone is 8.916 seconds?
Every attempt with the time-controlled loop runs way too quickly that no signal is output at the loudspeaker.
Many thanks for your help in advance!
Best regards
Takaroo

HI,
What you mean by simple way?
I recommend you to use LabVIEW examples provided by NI.
