No two recording studios which are alike. There are studios which still have equipment from twenty, thirty or even forty years ago. Some of these recording studio equipment are hi-fi turntables and amplifiers (the kind which use vacuum tubes). While most recording studios now depend on computers, and other digital recording studio equipment.
Common recording studio equipment include multi-band mixers, equalizers, tone generators, CD players, MP3 players, drum machines, keyboards, synthesizers, as well as a complete list of musical instruments. Of course, there would be the noise-reducing headphones and in some instances a metronome would also be present. No modern recording studio would be complete without a computer, and in some instances, some studios even have servers working together as one.
The choice in equipment is made on the basis of the expected output or on how good the quality of the result is. For an end-user or a consumer, it’s easy to dismiss the difference in quality between different recordings. However, most astute listeners will disagree and insist that the difference in quality is worth the cost and effort at achieving great quality recording.
