Auxit

LV2 Plugin, which sidechains can be delayed or phase flipped

The 'depth' or Z-Axis position in a mix can be influenced by a predelay in the reverb setting. The longer the predelay - or to be exact, the greater the difference between direct sound and reflctions - the further forward the instrument/voice seems to be. As you can see in the picture below, the direct sound reaches the listener much earlier than the first reflections if the sound source is close to.

With this plug-in you can use a common reverb for multiple channels and delay the sends to the bus. You can also rotate the phase. This can be helpful for other applications (e.g. comb filters).

To achieve that, I created an LV2 plugin that abuses the sidechain functionality to create a kind of delayed and or phase-flipped aux.

HowTo

1. You can add multiple instances of this plugin in a bus track.
2. Add a sidechain input in the Pin Configuration Dialog
3. In stereo tracks, Mixbus / Ardour add both chanels to one sidechain input. Two set it to stereo, in the source track (the track you selected in the sidechain) make a double click on the send header and add the right channel to the right sidechain input.

4. In the plugin, you can select the delay and phase flip

5. Add an reverb to the Bus, set the predelay there to zero and select the appropriate predelays in the "Auxit"-Plugin.

Unfortunately, it's not very straightforward, because you can't see in the plug-in which track it's for. There are probably still possibilities, I'll have to do some more research.
