Topic: ADI-2 DAC FS Spectral Analyzer issue?
I'm working on my speakers placement to get best frequency response.
I played testing signals on USB input (white noise, pink noise, sine frequency 1000 Hz) and at random realized that ADI-2 DAC FS Spectral Analyzer page shows different pictures as expected. Can someone repeat my testing or comment my results?
I tried different setup (testing samples from various web pages, Win10 - foobar with/without ASIO, MacOS, iPhone) - always got same results. Note: Spectral Analyzer in Foobar works as expected for my testing signals.
Is this the issue with Spectral Analyzer only? Or deffective unit?
White noise - in theory power density should be flat.
Pink noise - power density should fall off at 10 dB/decade
Sine 1000 Hz - Just 1000 Hz bar should be visible.
