Skype is a free, convenient way to greatly improve the sound quality of an interview or report. Two of my colleagues at WTOP, Ari Ashe and Dimitri Sotis have done extensive testing and comparisons of microphones over the past months to maximize Skype. Remember, a wired connection will always sound better than WiFi.
Here are their recommendations, in different price categories:
$10-40 Logitech USB H530
$50-80 Blue Snowball
$90-120 Blue Yeti In attached sound clip, the first voice is on a WTOP studio microphone, the second voice is on Blue Yeti, with a wired internet connection.
