VOR allows you to record only when there is sound, it will shut off automatically when it is silent.

In order to keep the device simple and easy to use, you can record ” scoop button functions ” and so on with the load one-touch system that customizes the display to your own taste. The Liquid crystal display corresponds to plural languages such as Japanese and English, and ID3 tag support for each file.
