Audio conversion device
There are several different types of audio conversion devices available, but they each perform relatively the same function, which is the conversion of one format of audio to a digital format for use on a computer. The most common types of audio conversion devices include cassette tape to MP3, LP record to MP3 and audio CD to MP3.
Audio conversion devices are basically either a cassette tape player, LP record player, or CD player with a connection to a USB port on a computer. The software included with the device records the audio playback from the audio media and converts it to MP3 format. Some devices allow for recording to other audio formats besides MP3.

This display allows users to view photos or video after the picture or video has been taken, which means if you take a picture and don't like the results, you can delete it; or if you do like the picture, you can show it to other people. Another nice feature with digital cameras is the ability to take dozens, sometimes hundreds of different pictures.
