This timely tutorial would make for a nice complimentary project for those of you who decided to build your own digital to analog converter after reading our post from a few days ago.

Vinyl records are analog (and awesome) but that doesn't mean you're limited to enjoying the sweet sounds through your Hi-Fi speakers.

Enter the Analog to Digital Converter (ADC) with the ability to convert an external signal to a processor readable value.

Connect your stereo amplifier to your PC's sound board and use the free, open-source Audacity audio-conversion software to create MP3s, WMAs, or other digital copies of your analog tunes.
