Greetings, Presumably your casssette machine has a phono output known as line out, if it is fixed level, no problems, if it changes when you alter the volume, set this about halfway.
Plug the (presumably 3.5MM) stereo plug into the line in of your sound catrcard. Set your sound card to line in. You now need some kind of program for receiving the audio, say, totalRecorder or GoldWave. Open a file of the acceptable parameters, i.e suggest .wav PCM 44,100hertz 16-bit unsigned stereo or flak, sorry don't know more about flak, because if you need to edit the file, not a good idea to use any form of compression until happy with the results. Start recording then start cassette, let it rip, turn cassette over don't stop recording, let it rip. At end of cassette, stop recording, save initial file, then save a copy on which you are going to work. Sort out file by editting joins, Etc. then save as is, or using whatever compression suits your needs. Job completed. remembere delete any work files you may have created such as the original recording. Hope these pointers are helpful.
