TRUCE surround mixes are made out of 4 stereo stems in 88 kHz 24 bit wav;
Lead guitar, drums, bass & scapes.
Scapes are mostly in the rears, bass in the front & sub, drums in the centerline and lead guitar mostly in the front and center.
Drums are moved a bit around using different technics to get the tom toms closer to the rears. That takes a lot of time, but is worth the effort.
Lead guitar are up front, but the last fraction of a second of each sequence of notes are moved past the center line in a way that the soli are coming towards you. Here is a difference between the 5.1 and the quad mix; In the 5.1 mix it moves just past the center line while in the quad mix it moves past you to the rears.
Besides that the quad mix have a bit gained the bass and lead guitar (without the center and sub channel)
Most of my surround mixes are made with a bit more living/moving quad mix inspired by the 1970’ties quad mixes. Often they were more discrete mix with moving instruments.
TRUCE surround mixes took around 2 weeks of work. Changing the 5.1 into quad only took a few hours; For me it’s important an album with a great sound is released in multiple ways so it can be received by most fans the way they prefer.
Releasing an album is like when your child has grown up and moves on from home. Should it live only cheap places (Spotify/Youtube) or may it also come more exclusive places (Surroundmusic.one)?
TRUCE is my 13 official album mixed in surround sound.
