Downloading and Using Files


Audio Files


Download these mp3 files and either transfer them to a cassette tape that will then be read into the dg system or simply play them on your pc/laptop with the dg system cassette interface in connected to the earphone output of your modern computer. This also works well with an iPod....

Phimon digital cassettes


These files are digital tapes in .wav format. The mp3 format results in "smoothing" of the audio data, therefore is not suitable for reproducing phimon tapes. First download the .wav file, then attach your computer to a high quality tape deck and record the output onto a high quality audio cassette tape. You should then be able to read the tape in your phi-deck drive.
