I am recording audiobooks with my setup and would like to start using the punch and roll feature with Audacity. I have Windows 10 and the newest version of Audacity. I’m using a Marantz cardioid condenser mic (USB) and a Scarlett solo.
As it stands right now, there is a latency issue when the recording starts again, a little burst of sound.
I never did tune the latency because I wasn’t sure how to do it with my setup. I don’t think the standard audio loopback cable will work here.
So apparently you have the Marantz Pro MPM1000, and not the Marantz Pro MPM1000U (USB) version. You are using the 3-pin to 3-pin XLR cable that koz has pictured to connect your Focusrite Scarlett Solo (3rd Gen) USB Audio Interface.
And you have your headphones plugged into the Scarlett and the Scarlett plugged into the PC.
I am thinking that you need to turn OFF Direct Monitor then hold your headphones to your microphone when you do your latency test: Latency Test - Audacity Manual
Then after you set your latency, turn Direct Monitor back ON.
But you have already figured all of this out for yourself.
