Few months ago I switched from an ASUS destop station to an AIO Dell computer.
With the ASUS desktop station the music output from the Asus Xonar Phoebus soundcard went directly to a pair of powered monitor speakers. With that setup i could also record music via internal DJ program or mic/line input with WASAPI setting in audacity. As I understand in this setup all windows/system mixers and ADDA converters are bypassed and done by the soundcard and routed to audacity? Right?
However after the station upgrade (downgrade) i was not that impressed with the music output from the Dell AIO soundcard so decided to invest in a good external USB DAC Audio interface (Teac UD-501). Music improved dramatically
When recording in Audacity the WASAPI routine can still be used (input device : Digital Audio Interface TEAC USB AUDIO Loopback).
But, I’m left with a few questions about that LOOPBACK routine :
The Music in digital form (pcm/flac) is routed via usb to the Teac device, converted to an analogue signal for the speakers output, but does the device also sends this analogue signal via same usb cable back to Audacity and bypassing every windows/system mixers? In other words, is what i’m hearing (corrected analogue signal) also being recorded by audacity or am i’m missing something and is the ADDA conversion done in windows system without passing the TEAC device ?
