In audio engineering, a studio monitor is a speaker designed to reproduce sound accurately and neutrally. Sound precision is important in recording studios, post-production facilities, and other environments. The typical studio monitor is designed with a flat frequency response, which means that all frequencies are reproduced at the same level without any boost or cut. Using this method, producers and audio engineers can assess their mixes more accurately. Conversely, a speaker reproduces sound for general listening purposes. Speakers are available in many different shapes and sizes, and they can be used in many different settings, such as homes, schools and indoor and outdoor events. For a more appealing sound, they are often designed to have a "colored" frequency response, which means that certain frequencies may be boosted or cut. In other words, studio monitors and speakers differ primarily in their purpose. The purpose of studio monitors is to present an accurate representation of sound, whereas the purpose of speakers is to convey a general impression of sound.
