Current multichannel spatial mixing practices are largely limited to the construction of three-dimensional space using two dimensional panning tools (meant for 5.1, 7.1, etc.) and those designed for common stereo production. A great deal of research is currently underway in spatial sound reproduction through computer modeling and signal processing, with little focus on actual recording and mixing practices. This investigation examines the design and implementation of early and late reflections and reverberant fields in 22.2 multichannel sound system mixing based upon research in listener envelopment. The techniques discussed will include the expansion of spatial elements into three dimensions using conventional tools and the implementation of multichannel impulse responses for reverberant fields. Listening tests were conducted upon the final music mix with positive results reported for listener immersion.
