Just bought a new phantom powered condenser mic. When I try to add new traks to existing projects with new mic, I get message (latency correction setting has caused audio hidden before zero) Settings are buffer=100 correction= -130
Is it a USB microphone? What make/model?
If not a USB mic, how is it connected to the computer?
The message that you are getting is because the recording is failing as soon as it starts, which is creating a very short track that is “hidden” because it is entirely before time=0.
And you should know by know to always tell us your version of Audacity and version of Windows. 
See the pink panel at the top of the page.

2.1.2 windows 10 mikes are run thru a Audiobox usb. It is not only happening with the new mike. Something will not allow me to add additional tracks now. project rate is 44100.
solved it was a reload and reboot thing. usb box.
