Why no phase invert on bus tracks?
Seems a bit of a waste to have to stick a channel tool on a bus track just to flip the phase. Or is it there somewhere and I just don't see it?

Not seeing it, or I can't see the forest for trees. Every audio track has a phase invert switch, but I don't see any on a bus track, looked at inspector and the bus i created in the console... nada. Insert stereo bus, no phase switch.

a phase invert switch doesn't make sense for a stereo bus. what are you wanting to do with a phase inversion on the bus?

+1. The Phase button is actually (AFAIK) Polarity, which can only exist where a wave file is.

For example you stick a PC4K gate on a bus, use something like a kick to trigger the sidechain then stick the EQ after the gate. Now you route something like a large bassy pad though the bus but also send the signal via a send to the master out and flip the phase on the bus. Everytime the gate opens you get phase cancellation of whatever frequencies you carve with the EQ, this way you have something akin to a sidechain EQ instead of duckinf volume you duck the bass which is a lot less noticeable in the mix. Just one example, lots of fun can be done playing with phase cancellation.

That is interesting. I have often seen people clone tracks, reverse polarity of one, and then use EQ sweeping or other effect on one track to create an interesting sound (like an extreme wah-wah or a quasi-envelope-follower sound), but, to Beagle's point, this requires recorded audio.

Although that is definitely a creative use of phase cancellation, how about just using Dynamic EQ (e.g. Voxengo GlissEQ, BrainWorx DynEQ) or one band of a multiband compressor on the bus to reduce only the bass content above a threshold?

I mostly did it this way because I needed the ducking of the EQ to be based on another track and I couldn't find any way to automate it, drawing in automation would be a nightmare. It's a nice way to have 2 tracks that competes in the same spectrum without compromising one or the other by applying a static EQ or volume ducking with a sidechain compressor. When one needs the room it ducks the spectrum it needs on the other track. Done with bass in a full mix you can hardly hear it's being done. I'll have a look at the EQs you mentioned.

The only way that i know of is to use the channel tools plug in to reverse the phase. I have done this with effects and it works well. There is not anything built in the bus that allows you to do this. But channel tools works great for this.

That's what I resorted to also, but there's a bit of delay added so you don't get complete cancellation. Currently looking at the Blue Cat plugins, most of the analyzing vsts they have can send automation CC's based on peaks so that might be a better solution to automate things like EQ in realtime.

Kenneth, Yes given your example I can see that, and I can see the need for a lower latency solution. When I used phase reversal it was with two buses that had identical stereo effects and parameters, I sent two identical signals reversing the phase on one of the buses would cancel both effects with no loss of latency or delay. Then adjusting some of the parameters in one of effects on one of the buses caused only the tail end of the effect to be heard. Great studio trick, but your example calls for a lower latency solution. Let me know what you find. I also looked at those blue cat plug-ins

I'm still contemplating which one of the blue cat plugins to buy, I'm thinking the "Digital Peak Meter Pro" is probably the one having the lowest added latency.

I just discovered the phase trick with purchased stereo drum loops. i was struggling with standard EQing, until i tried the "carving" technique with 2 tracks out of phase. FANTASTIC! my drums POP now. only issue is organization. i usually have a track for grooves and another for fills. with the phase EQ trick, i need a pair for each spectrum carve. basically kick, snare/tom and overheads. that's 12 tracks. i had the BRILLIANT idea to have 2 tracks (grooves and fills) AUX sending to 3 pairs of busses. but alas, no phase button on the bus. makes sense though, you need wave data to invert. looks like some options out there though... ... AAAND this little guy recommended by Bristol_Jonesey worked like a charm on the BUS http://www.softpedia.com/get/Multimedia/Audio/Audio-Plugins/RS-Phase-Reverse.shtml it's bare bones, and has a LITTLE sonic residue - but workable:  there may be other, better plugins for this, but this gives me hope AND keeps my track count down. i'd rather bus than track. nice stuff! this phase "carving" trick is the friggin' POOP!!! it's kinda like an ALPHA MASK in Photoshop. damn, my nipples are hard with this stuff.

If I understand the aim of this routing correctly, couldn't you achieve the same thing by side chaining one band of a multiband compressor?

If I were looking to invert phase on a bus I would use Channel Tools or use an Aux track instead of a bus. I would avoid 32bit plug-ins where possible.

Yes that was my second thought - use an aux track, it does almost entirely the same thing as a bus track and may even be more elegant since you can keep it next to your source track.

Channel Tools is a newer plug-in to consider, if you elect to use a bus instead of an aux track. Aux tracks have a phase button like regular audio tracks.

what channel tool process does phase inversion? this phase VST is simply a phase reversal... no heavy lifting i would think. i don't think 32bit should be an issue with this doodad. again, this is just to organize things to my taste. push comes to shove i will just leave the phase thing to the tracks and use folders/groups (which i am using now).

the plug-in is called "Channel Tools" It is available in Professional and Platinum 32bit plug-ins load in an external server. No matter how trivial the plug-in there is still the overhead of the 32bit bridge.
