Actually I am also very interested in people's solutions to this. Please help! Especially for many of us who are not migrating to MIR quite yet...
Here's the technique I have so far. I think it can be improved a lot more, though...
- a slightly narrower stereo separation for strings at the center of the stage. For me, that's Violin II and Violas. "stereo separation" in this case means tweaking a stereo imager or a power-pan, either way. This helps make the inner instruments sound just slightly smaller and slightly behind.
- Using one manually created early reflection for each section, panned to the extreme left or right, whichever is the opposite side of where the instrument is originally panned. for example, I have violin I panned to the left, taking approximately 1/3 of the stereo field, and this manual early reflection is panned extreme right. This is implemented by sending to an additional channel that has some delay. (and make sure you are sending both stereo left and right channels without loosing information when panning it) for instruments closer to the center of the stage, I use a quicker reflection, and for the instruments on the sides, I use a slightly longer reflection. The actual milliseconds depend on the type of reverb being used - if its intended to be a large hall, the delays should be slightly longer (~50 ms for inner and ~70 ms for outer instruments) for a smaller hall or a tighter sound, the delays should be quicker (~25 ms for inner and ~35 ms for outer instruments). Then, I also muffle high frequences a little with EQ or filter, only for these extra reflections. Finally, the reflections are significantly reduced dB compared to the original instrument.
- because of this additional early reflection, its easier to pan instruments wider, to get a better stereo effect without making the strings sound too thin.
- it might seem that adding the early reflection would make it sound less stereo. At first I expected to abandon this experiment... but to my surprise, it did not ruin the stereo effect at all. I think its the psychoacoustics of early reflections - the correct combination of delay, panning, volume reduction, and muffling high frequencies. Instead it makes each instrument sound solid enough to play solo without sounding thin.
If anyone is interested, they can search my earlier posts and see a link to the song "galactic swashbuckler" where I'm using this technique (in the strings only). I think the strings still do sound a little thin, but it was still a noticeable improvement.
