Hi!
I currently have a QuantAsylum QA-401 Audio Analyzer. I've been using it for testing my current project, a headphone amplifier. I've made a lot of equipment around it to be able to measure lower THD with a super low THD signal generator and a twin-T notch filter. But here's my problem. I want to measure DACs. On my list is to see if different power supplies have any effect on my newly bought Topping D50 DAC. I've seen some proper measurements from some of the people on this forum, like @March Audio doing it with the QA-401.
So here's my question. Because I can't use the QA-401 output, I need a software signal generator or downloadable files. Any tips on where and what files I need to characterise a DAC would be much appreciated. I've tried some generators and downloaded files, but get different results. What is needed is a small How-To for DAC measurements. Anyone up for writing a short guide?
