Years ago, I owned a small Behringer analog mixer that I used to record the songs I wrote (see "Your Love Is Near" below). That mixer eventually blew up and I didn't record anything for about 10 years. In 2010, I purchased a Behringer XENYX1204USB mixer, shown in the picture above. It was a huge step up because it let me digitally record via USB. This eliminated a lot of noise that is so prevalent in the typical computer's sound card. It also has some decent built-in effects, which is another plus.
I used Adobe Audition for the multi-track recording and post processing.
