Hi
I am trying to use MyRIO to measure sound pressure level using an electret microphone connected to the audio input and the Sound and Vibration Toolkit (all software version 2019)
I am using the FPGA high throughput personality to acquire at 44kHz as shown attached
Then I scale the signal, I apply frequency weighting and I compute the LEQ using the appropriate VIs from the S&V Toolkit
But if I select A-weighting the "SVT A, B, C Weighting Filter (Fixed Rates) VI” generates an error (shown in the attached file). If I select linear no problem. Of course I have also tried updating “channel info” accordingly
Any ideas why? Are there any incompatibility issues between MyRIO and SV Toolkit?
Any help would be much appreciated. Thanks!
Best regards
Guillermo
