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. The COVID-19 pandemic and COVID-19 lockdowns resulted in a dramatic global increase in the number of remote workers in 2020, which is anticipated by experts to remain a permanent shift in the field of sound recording when the pandemic ends. Studio equipment Until the late 1970s, music could be recorded either on low-quality tape recorders or on large, expensive reel-to-reel tape machines. Due to their high price and specialized nature, reel-to-reel machines were only practical for professional studios and wealthy artists. In 1979, Tascam invented the Portastudio, a small four-track machine aimed at the consumer market. With this new product, small multitrack tape recorders became widely available, and grew in popularity throughout the 1980s. In the 1990s, analog tape machines were supplanted by digital recorders and computer-based digital audio workstations (DAWs). These new devices were designed to convert audio tracks into digital files, and record the files onto magnetic tape (such as ADAT), hard disk, compact disc, or flash ROM. The way the room sounds or reverberates can change dramatically the way music is mixed, written, and recorded. Untreated rooms have an uneven frequency response, which means that any mixing decisions being made are being based on a sound that is ‘coloured,’ because sound mixers can not accurately hear what is being played. Acoustic panels and bass traps can improve the sound in the room. Impact on professional recording studios Professional recording studios have been heavily impacted by the growth of home studio technology over the last two decades. The advancements in such technology along with the moderate to low budgets of up-and-coming and even established artists have put many commercial studios out of business. Many professional engineers have moved from these commercial studios into their own homes to be able to work with
