Nugen plugs are nice, this is my new fav though

Voxengo also makes a FREE one, not as pretty and less features but it does the job well

OK, let me rephrase - although I may be confusing some technical terms.

Case A: I have a mono synth in a track. I place a stereo sample delay effect as an insert. Left channel untouched, Right channel 10ms delay. This goes to main bus. I'm pretty sure this describes the standard case of Haas effect.

Case B: Same mono synth. It's output (stereo track with exactly the same signal on L & R channel) goes to main bus. Additionally, I send this signal to an aux bus. On this bus I place the sample delay with the same settings as in case A. (If I solo the aux bus, I now have exactly the signal obtained in case A.) But after the sample delay I insert a MSED plugin which I use only to mute the MID - so my aux bus will output just the SIDE of the pseudo-stereo signal, additionally I will highpass at 400 Hz this signal. This SIDE signal goes to main bus. So the main bus is summing a MID signal and a SIDE signal resulting pretty much the same "stereo" signal as in case A.

---

Testing case A: when placing a utility plugin to make the mix mono, processing a mono signal together with a delayed copy of the same signal is leading to audible artefacts to some extent.

Testing case B: when placing a utility plugin to make the mix mono, this will essentially kill the entire SIDE signal sent by the aux buss leaving the untouched initial mono signal.

I've tested this alot with synths, drums, vocals, it's always the parallel setup that wins every time.

 

PSP Pseudo Stereo is the only plugin that can create stereo from mono source without too much hassles. close this thread.

 

Nice! Do you pan the original/unaltered mono track? Sounds like you have created a pseudo-M/S technique (where the sides are cancelled out when mono-summed in the master, just like M/S mic'ing). Nice! Thanks for the explanation!

 

I never tried panning the mono, but I'm thinking a "direction mixer" plugin (not the pan-pot) applied with the same settings on both mono and sides will lead to the same result and have a panned sound source.
