When Jewish children begin their religious education, they participate in a Consecration ceremony, at which their Hebrew name will be used. At a child's bar mitzvah (for boys) or bat mitzvah (for girls) - the Jewish coming-of-age ceremony at the age of 13 - he or she is called to the Torah for the first time by their Hebrew name. At a Jewish wedding, the Hebrew names of the couple are used on the ketubah, their Jewish marriage document.

Sound Recorder is an app you can use to record audio for up to three hours per recording file. You can use it side by side with other apps, which allows you to record sound while you continue working on your PC. (While there is also a desktop program called Sound Recorder, this article is about the Sound Recorder app.)
