Purchase or rent a building apart from any other business or residence. Make sure it's in an area where your neighbors will not complain about noise.
Perfectly straight rooms with four defined corners is bad for sound acoustics. Search for a room that has walls that do not meet at 90 degree angles.
The mixer is your most important piece of audio equipment. The actual recording of the music goes into the mixer, which eventually serves as your mixing central station.
Every studio has at least two rooms. The main room where the mixer is placed and the sound engineer and producer work, and the second room where the talent performs and records their music.
Make sure you include basic music equipment like microphones, mic stands and pop filters along with other needs, such as water for the band and a restroom.
