Measurement: inner matrix dimensions must agree

I'm trying to measure the frequency response of a signal chain that consist of a 2 channel mix, fed by a fullrange signal and an all-pass filter (2nd).  I have markers inline ahead and downstream of the blocks I'm interested in.  I get an error "Inner matrix dimensions must agree".

What's that about?  Ideas on how to fix it?

Can AudioWeaver plot frequency response from an actual measurement, or is it always calculating theoretical FRs multipled out?

 

thanks for you help,

 

John

Hi John,

There is actually a problem with the FR function in the Mixer_v3_module.  Thanks for bringing it to light.  I've flagged a ticket with our development team about this.  Unfortunately for now, the Mixer_v3_module can only be used in a FR plot with 1 input pin (although the single input pin can still accept multiple channels).

To answer your second question, Audio Weaver plots frequency response by calculating theoretical FRs multiplied out.  It gets updated based on the arguments/variables of the modules.

Thanks,

Kevin
