Pros
With the use of a simple .cmd (batch) file, this is a most excellent program for recording audio without the need of setting volume levels, etc. I used it every week buy and it's completely automatic
Cons
The counter is in seconds online, gets a bit awkward after about 10 minute and typing the STOP commend gets over-written with the seconds counter. Annoying but not show-stoppers. The Pros far outweigh the cons!
Summary
If you have repetitive recording that you need to perform, this simple utility might be just what you need!
