Connect one end of the mini jack cable to the headphones or line out socket on your cassette player. The line out socket will provide the best quality signal but not all players have them. Connect the other end of the cable to the microphone or line in socket on your sound card (again the line in socket will provide the best signal). Place your audio cassette in the cassette player.
Download and install some sound editing software (such as Goldwave or its free alternative, Audacity) if you have not already done so. Boot the software and press record. Press play on your cassette player and monitor the volume your audio cassette is playing at. If using the headphones socket on your cassette player, adjust it up or down to achieve a good volume (near the top of the “green” sound range on your software).
Press stop on the software and your cassette recorder. Close the sound file on your software and rewind the cassette to the start. Press play on the cassette and record on the software. Pause the software when you turn over the cassette and unpause when you start to play the other side. Save the audio file when the cassette has finished recording. Use the wave (.wav) file format for best sound quality.
Process the sound file using the hiss reduction filter to remove any hissing on the sound file caused by the cassette playback system. Save the audio file again. Copy and paste each song or block of audio recording into a separate audio file to create “tracks.” Save each track as a wav file. Download and install CD recording software (such as Roxio or Nero) if you have not already done so. Close the sound recording software.
Boot your CD recording software and create a new Audio (not Data) CD. Drag and drop each track into your new CD file and arrange them in the order you want for playback. Insert your blank CD into the CD burner. Press the “burn” or “record” button to start the recording. When the recording has finished, you can delete the audio files you created, or save them for later.
