Sorry, I may have mis-spoke yesterday w/o actually having the PC at hand to try... while Sound Recorder is an easy way to make silent tracks, it seems limited in the length of the track it'll record to a minute? No matter, you downloaded GW and that'll fix you right up.
But these sorts of discussions can be stimulating for us old farts that think we know it all already. Tooling around with Sound Recorder just a moment ago I figured out another way to make 16-bit, 24KHz recordings in with my set-up on my trusty old beater laptop (IBM Thinkpad 1400, Pentium II 266, MMX, Win98, Yamaha OPL3-SA sound card, Labtec AM-222 microphone)simply by changing the properties in SR. Can't say for sure whether this is a function of my particular sound card and it's software plug-in, so dunno if it'll work for anyone else with other PCs...
Noted some time back that this worked in Goldwave--that I could get better than CD specs out of my recordings. Happy to get more than 22 KHz on the top end with consumer grade stuff. I'll take another 8% even if I can't hear the difference myself!!!
