Direct CD Reference Track
Sound production rooms acoustically contribute to the perceived sound of the music or speech. The arrival time, direction and temporal density of the early reflection pattern, coupled with the various early to late energy ratios and decay time, level and temporal and spatial density of the late reflections define the sound that is heard. The sound we hear is a combination of the instrument and the room:
Untreated 10' x 14' x 19' Test Room
Sound reproduction rooms, on the other hand, should be neutral. All of the spectral, timbral and spatial information is pre-encoded on the playback media and the room's only function is to allow a critical listener to hear what has been recorded, as is was recorded. As opposed to a music production room, a music re-production room can only add acoustical distortion and corrupt the music reproduced:
The Same Test Room, with RPG treatment
The RPG treated room produces an exciting and enveloping rendition of the reference music with minimal acoustic distortion. It is remarkable the extent to which a properly treated room can reduce acoustical distortion and accurately reproduce music:
