This is an extremely simple effect, ThreeD

It is a mono->stereo widener with just three controls.

Here is an audio sample.

An acoustic guitar, mono file.

The sound starts mono, then ThreeD comes in, again mono and so on, while changing parameters.
No reverb added.

ThreeD_Guitar
(guitar by Jerry Mateo, thanks!)

It is NOT a mid-side processor. Mid side cannot act on mono sources, of course, because they don't contain side component to balance.

ThreeD adds stereo width and dimension in a frequency based way, from complete widening (full spectrum) to subtle air widening (high freqs only).

It is very useful to give each source in the stereo panorama its dimension (instead of being a point source) without adding reverb or delays, so keeping it very clear.
From extreme strings widening to subtle clean guitar stereo width.

***EDIT

It is available now.
It contains several Mono->Stereo and Stereo->Stereo algorithms, based on phase, time, panning and is a great time aligning tool, too (multitracked guitars?).

How does it widen without using m/s processing?

actually really cool effect I cant wait to try this out

To widen a mono source? More than likely just Haas or Comb filtering. Should be interesting.

its pretty cool though. its probaly a great way to add some wide effects so somthing in the mix

We cannot add width through mid-side on a mono source because there:

L = R
Side = L - R
-> Side = 0

So you need a way to generate Side, not just balance.

Some ways to get it from mono are comb filtering, phase rotation, delay.
Each one has its own faults. comb may sound phasey, phase rotation may be subtle or not mono compatible, delay can go back to combs and delete frequencies and not be mono compatible and so on.

This one uses a frequency based spread of the frequencies in the stereo panorama. The frequency control sets how frequency ranges are affected, to get a natural effect.

What I like is using it as a tool to add dimension without adding reverbs or delays, so keeping it cleaner and drier. Used a lot to manage stereo width on www.plootoh.com

makes a lot of sense really. I like how it made my really really bad recordings of guitars sound kinda cool

those are super old recordings.
so It is more for something like setting space for multi vocal parts and stuff?

Does it work on stereo sounds too?

it mixes the left and right into mono I asked to That would be cool

It is stereo in stereo out.
The current algorithm mixes inputs to mono and then builds the stereo image.
Probably it is very useful in a send use. Add a bit in parallel, like with reverb.
The small upper right menu is for future modes, thinking about a stereo mode.

a stereo mode would be really cool sounds great though works wonders on mono signals

You can also create a pseudo stereo fx using opposing equalizer curves on each channel.

quintosardo · Post by **quintosardo** » Tue May 22, 2012 9:29 pm

Yes, of course, you can do a trivial effect with two complimentary eqs, but it spreads the notes on the stereo panorama, not the details of the sound, if you don't set enough spans of the spectrum (LRLRLR...).
Also you can introduce phase effects if the equalisation isn't the more suitable one....

This one uses a similar principle, spreading frequencies on the stereo field several times. But it is frequency based, too, so the effect can sound natural, and with many passages, so even single notes have width and melodic passages don't sound spreaded from left to right.

sorry,but tell me one reason why not use 2 mics and get much more natural sound...instead of use 1 mic + ear fatiguing effect???
