I recently had the pleasure of writing an article for Audio Times on phase coherence in studios, control rooms and performance spaces. You can read the entire article on the Audio Times website, but here is a little to get you started:
The art and science of acoustic design for control rooms and recording studios has evolved steadily, from 1930’s Bell Labs research, to the ‘70’s nearly-anechoic spaces, to the ‘80’s LA-style compression ceilings, to the 90’s quadratic-residue rooms. But the continuing trend toward recording in homes and small project studios has left many professionals wondering if studio acoustic design is now ‘devolving’. At Acoustic Geometry, we feel strongly that the challenge of consistent, accurate, and phase-coherent acoustics in smaller rooms is definitely moving forward.
