Digitize your audio cassettes with the Pyle Pro Dual Cassette Deck with MP3 Converter. This unit features a pair of cassette decks that allow you to copy from one cassette to another, or copy from cassette to MP3 via free Audacity software and a USB connection to your home computer. Cassette-to-cassette copying can be accomplished at normal or high speed, and dynamic noise suppression reduces hiss and artifacts. It is compatible with conventional metal or chromium dioxide (CrO2) tapes. RCA line-in and line-out connectors allow you to hook the deck up to stereo systems while a USB port connects to your Mac or Windows computer for MP3 conversion.
