This converter is a simple solution that allows you to digitize your audio cassette collection to MP3. Take them digitally and share them again with your family and friends. Similar to a Walkman-style cassette player, it has a USB port that connects directly to your computer and it comes with a full built-in audio editor, Audacity. With the included software, you just need to press \"play\" on this cassette player and record into the software. The audio will then be captured while playing and can be exported to MP3. You can now burn it to a CD, download it from the Internet, or transfer it to your smartphone. It couldn't be simpler. A headphone jack allows you to listen to tapes directly and this MP3 converter can operate with two AA batteries, a USB power source, or a DC input.
