Labcat asked me how she can convert her old cassettes to CD. I decided to post here in case anybody else is looking to do this.
1) Pull out your old cassette player. You can use either the headphone jack (1/8" or 1/4" port) or the audio outputs (usually RCA).
2) Identify the line-in port on the back of your computer (usually a single 1/8" port).
3) Purchase the appropriate connector or you may happen to have the right one stuffed in your junk drawer. You won't spend more than $15 at RadioShack.
4) Connect cassette player to your computer, and test by playing a cassette. You should hear it through your computer speakers in stereo.
Now you need software.
5) Download Audacity. It's free (but always good to donate if you like the software).
6) Record to MP3 and store or burn to CD.
7) Crank it up.
8) Drink a cold beer or spark a spliff or both.
9) Repeat No. 8
10) Repeat No. 9
Voila! You just converted all your tapes for less than $15, while everybody else is purchasing USB cassette players with shitty software for about $150. ROFL!!
Here's a how-to video from a friendly English chap.
