After struggling quite a bit with the DIY tube-coupler and in the interest of making my graphs compatible with other graphs out there for easy comparison, I decided to get an IEC6038-4/IEC60711/IEC711 coupler. This is a Chinese knockoff which is supposed to be pretty close to the real deal.
Setup
- Hardware: Laptop > USB Audio Interface > Sound Card (Mic In) > IEM > IEC711 coupler > Sound Card (Front Out) > USB Audio Interface > Laptop.
- Software: Room EQ Wizard (REW)
