Home recording is the practice of recording sound in a private home instead of a professional recording studio. A studio set up for home recording is called a home studio or project studio. Home recording is widely practiced by voice actors, narrators, singers, musicians, podcast hosts, and documentary makers at all levels of success. The cost of professional audio equipment has dropped steadily as technology advances during the 21st century, while information about recording techniques has become easily available online. These trends have resulted in an increase in the popularity of home recording and a shift in the recording industry toward recording in the home studio.
