Hi Luggers, I'd like to initiate a Logic surround thread here. How are people using Logic to create good 5.1 music for DVD? I guess most people produce for DVD-Video and has to deal with that Dolby audio compression? If producing for DVD-Audio or SACD, would be a better idea to record with some DSD gear since Logic is PCM based? Please, anyone with surround experience of Logic, post your findings! I'm starting out a DVD-V project mix here, ten songs to be 3-D'ed in Logic. I've done two songs as a quick pilot test and this is the best method I've found so far: 1. Creating the music in Logic the usual way. 2. Mixing for stereo as usual. 3. Using the "phase reverse psycho-acoustic" mastering technique to produce a stereo master. (Method: two stereo clones summed; one with phase reversed and one with L/R reversed. This summed signal - now with "a hole in the middle" - is finally summed with a third clone of the mix that has been "monofied".) 4. Bouncing the final wide-stereo master into two 24 bit mono files, Left and Right. 5. Saving a copy of the original Logic doc (not the wide-stereo- phasing mastering setup) for doing the surround mix. 6. Setting Logic audio preferences to surround 5.1 without center speaker (my choice). 7. Connecting four speakers and a sub woofer to 5 sound card outputs. 8. Importing the Left and Right wide-stereo-mastering files to be used in the surround mix as Front Left and Front Right. 9. Mute all other tracks. 10. Start unmuting tracks while setting the channels to surround and placing them by ear in the mix (if possible). 11. Using a 60 Hz hi-cut filter on the output used for the surround sub bass channel. Eventually also a compressor (I have not yet found any need to cut out the bass under 60 Hz from the other surround channels. In Logics surround control interface for each sequencer track there is a special sub woofer send and I have found this to be enough for my needs.) One trick I found especially cool is to use the reverb busses from the first stereo mix also in the surround mix, but put a small delay to the reverb by inserting a stereo delay plug-in set to some value that sounds good in the context. For synths it's cool to try out different, but similar, sound patches and now place the part in the rear speakers (the part already playing at the front since it was part of the original stereo mix). --> Dynamically beat synced surround effects: Some years ago I did a four-channel mix for a movie. That was before Logic got surround support (actually before 5.1 was invented, I think) and then I used the Vector Objects in the environment to make cool stuff happening in the surround field. Now, with surround support in Logic, you should be able to do a lot more than is actually described in the manual. Has someone yet experimented with that? Thinking about things like setting up delay systems that bounce around the surround field in a circular manners, etc. I mean, a vector object could be automized or maybe patched into being controlled by some other dynamically beat synced plug-in... don't you think? (I'm just asking in case someone already has done this and if that's the case I could cut down on my experimenting time by receiving some advice ;-) Greetings from Sweden Per Boysen www.looproom.com (international) www.boysen.se (Swedish) ---> iTunes Music Store (digital) www.cdbaby.com/perboysen
