No it isn't. Both compression and expansion are effects. I've used them both extensively in the studio. To a limited extent you use one to reverse the other... on an individual track. However, on a mix which contains multiple different simultaneous compressions/expansions often with frequency-limited bands (there really isn't enough space to explain all of this here) + overall compression of some sort, there is no way to accurately "undo" mix compression. Sure, you can slap a dynamic "exciter" / dynamics processor across a mix and make it "lively" again but this is a major FX treatment and has nothing to do with the original mix master. I'll try another way. The end results of track + sub-mix/group +master Compression and expansion are non-linear and non-deterministic. So you can't "undo them" accurately. All you can do is add another layer of FX to the end result! A dynamic range expander is a creative effect. It has nothing to do with accurate reproduction. Slapping a DBX, BBE or whatever across a mix can be fun, but... -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...SB3+Stontronics PSU - Altmann JISCO/UPCI - TACT 2.2X (Linear PSU) + Good Vibrations S/W - MF Triplethreat(Audiocom full mods)- Linn 5103 - Aktiv 5.1 system (6x LK140's, ESPEK/TRIKAN/KATAN/SEIZMIK 10.5), Townsend Supertweeters, Kimber & Chord cables Outdoors: Boombox+Creative Sub (If I remember to turn it on...) ------------------------------------------------------------------------ Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=57872 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
