WAVs and RealAudio are no longer used on this site. It is all MP3 now. These days it is not too hard to find a cheap box with plenty of pizazz and spark. You must have a sound card and a set of speakers, headphones, or some other audio output device. Compression using MPEG Layer 3 format necessary results in some slight signal degradation, but it is minimal and can be tolerated.
Some Dead tapes sound better cranked up and heard in another room, anyhow.
