Hi All!
I'm looking for a analyzer software to test the noise/THD/bandwidth of the summing mixer i have designed. I found a software: True RTA,
https://www.trueaudio.com/rta_abt1.htm that seems good for this purpose.
I have a quite good audio interface: UMC-1820. bought recently.
¡Any comment about this software is wellcome!
¡Thank you very much!

Hello,
You only must be careful to not overload the input.
If you want to measure the THD from an output of amplifier, you will
need to add a resistor divider (attenuator) to have a signal level at
input of sound card of about 1-2V max.
You must also be careful that some amplifier with BTL output can't
be connected directly because each output wire are active (no ground).
