Keep in the back of your mind you're replacing a studio and recording engineer. Those jobs didn't go away. You're just figuring out a way around them.
Home recording can give you certain contradictions. It's a terrible idea to keep a noisy computer in the room with you. It's a terrible idea to record without seeing the screen and recording meters.
One of the recommendations is to remote or extend the keyboard and screen. That does work. The ACX Demonstration method is use a MacBook Pro or other machine that makes little or no noise in normal operation.
The Windows people then leap up and accuse us of "wasting" all that money on a Mac.
Since you can't see the screen and you're not wearing headphones, the crunchier bits of your performance might be overloading the computer by speaking too loud. When you stop the recording at the end of the performance, make sure you have View > Show Clipping
selected. That will produce little red lines in the blue waves of all the places you have permanent sound damage from overload. Control-F to show you the "Full" show.
If you have very serious tonal or quality changes between different normally recorded passages, you may have some of those Windows automatic tools still in service. Did we ever send you into Windows to search for those? Windows normally thinks you're trying to perform a business conference, not record an AudioBook.http://manual.audacityteam.org/man/faq_ ... hancements
