We bought a Samson CO1U, a large condensor, USB connected, microphone for direct recording to a computer.
The microphone includes a USB cable and a 2.75″ (69.85 mm) table top tripod stand. I recommend a heavy desktop base like this On Stage DS7200B Adjustable Desk Microphone Stand and the Samson SP01 Shockmount, which cuts down on vibration when that truck drives by, but makes it look really professional.
It’s pretty much plug and play with Windows or Macs, but Sansom has a “software preamp,” SoftPre applet, that has an input level meter, volume control, high-pass filter and phase switch.
Skype will never sound any better.
