How does one copy cassette tapes to computer?

With this; you can input the casette deck's signal, via your computer's stereo mic input and a stereo 1/8" to dual RCA adapter. You can then save the files to a wide variety of formats, at various sample rates, of your choosing(ie: Hi-Rez MP3):(http://download.cnet.com/Mixcraft/3000-2170_4-10285311.html) There's a free sample download available.

Hello Al- Mixcraft can use the stereo 1/8" mic input and(if needed) levels can be adjusted by navigating the computer's 'Recording Devices', 'Microphone Properties' and 'Levels' windows(re: Windows Vista). I've got Mixcraft on my laptop(no Line-Ins), and often use it to record directly(Mic-In) from the AUX OUTs of the Mackie Onyx 32.4 on which I mix(weekly gig). I've saved a large number of audio casettes, going to the 1/8" mic input(mic level set at 85), then burned Audio CDs from the files. The program simulates a mixer console, and multi-channel digital audio recorder. It can work with an audio input card, with Line-Ins, as well. It won't, "arm" a mixer channel, unless something is plugged into an audio/mic input and speakers/headphones are connected(gotta have analog ins and outs).
