Much like Joe I do the following

I have a cassette deck and run the output to my amplifier.

Out of the amplifier there are two phono plus which go from the output which go to a jack adapter which plugs into the LINE IN input on the computer which is probably on the back. For some reason they only seem to put Microphone sockets on the front (presumably for Skype and stuff). You could use a lead like this to do the same

You may need to go into the sound settings on your machine. Probably Control Panel - Sound - Recording tab and choose Line In as the input and play with the levels until you get it right without any clipping or distortion.

Audacity would be fine or any other software or DAW. You just choose line in as the input and again balance levels so that it's ok.

Then listen and record.

You could experiment to cut down on the need to do the recording in real time with doing it set to fast forward and then slowing it down in audacity. Be interested whether that works.






















Sorry that was a joke...
