I tried with both JACK and ALSA on Linux, with a SoundBlaster Audigy card. Recording works quite fine in OBS studio.
I just tried it again now even with everything else muted, since its a compressor mic with no preamp it’s quite low, and if I put on an amplifier plugin loud enough for me to actually hear my voice it’s as if it gets echoed into something almost robotic sounding. So its like the master monitor gets recorded? It’s strange though because even if there’s nothing on the mic track already there’s a horrible echo in my speakers and that gets recorded. I’m not able to get an audio output on anything else like VLC or YouTube while Ardour is running so I’m not sure if its recording my whole system audio or just the Ardour master.
If I record it first without the amp so that I can barely hear it, but see it pick up on the channel signal level indicator, and apply the amp plugin after, then it sounds great. However, again if I try to record on the same track after the amp is on, horror ensues.
I can’t see a Loopback on the
alsamixer options, please see the attached images:
