Stereo Expander - Improve the sound quality

Staff review

Stereo Expander

Very straightforward dsp effect... some configuration would be nice to have... .such as a slider for amount of stereo expansion.


Excellent - Zero distortion, simply does what it says. Great sound. It works very nicely using the rear speakers on my 4.1 setup. I use Simply Surround by Sergey Shamshin when I want more pronounced fidelity and Stereo Expander when I want softer surround sound. Gave it a 4 instead of a 5 since it doesn't have a level to adjust. Great plugin! - June 26, 2007 by Avi I

does what it says, and does it well - Very reliable and fast. Unlike some dps's this just does one specific task. It takes sounds that are off center and makes them more so. So if a sound is 25% away from center to the right, it will sound more like 50% off center, or something like that. The result is that the audio seems more spread out, it's a distinct difference. It does nothing to mono files, it would have to pull something out of it's virtual ass to do that. Also, it puts out a very clean sound, there's two ways to increase stereo separation, delay one channel slightly, or go in and actually modify the content of each channel. I suspect it does the former, because when I unplug one of my speakers and toggle the plugn I hear no change in tone or volume. By delaying one channel your brain is tricked, but bass response is altered too. If the bass was out of phase between the channels, it might increase with this plugin, if it was in phase it will become out of phase and therefore partially canceled which means weaker bass. *Note: If your looking to something to spread out audio while wearing headphones download "reverb/speaker simulator", which does processing to make the headphones sound like speakers in front of you rather than inside your head. It has virtually no effect on regular speakers though, which is good. - December 16, 2005 by keith d

Nice - I've used this plug-in for ages, and every now-and-then I take it off, and say "sheesh, this sounds crappy" and put it on. Amazing, simply amazing. Best plug-in ever, no doubt. - July 30, 2003 by Demooni W.

One Word Incredable - I have Quad Speaker with a subwolfer... I thought my sound couldn't get any better, but you proved me wrong. I have never heard such rich livly music come out of my speaker too bad i couldn't use your stereo expander for all my games that would be the iceing on the cake.... :) Great Work!!! - June 25, 2002 by Matthew Wagner

Efectivly simple! Simply Efective! - This was the way God intended us to hear music! It's so simple to use, just activate it in the preference screen and boom! Bow down to the amazing sounds of TRUE STEREO!!! - June 23, 2002 by Jeremy Emfinger

Why doesn't work with MuchFX? - ??! Hey good Plug-In but Why doesn't work with MuchFX?... - April 4, 2002 by Jafo C-Null

Useless - It enhances sound a bit. You will download air. - November 2, 2001 by Giacomo D.

Use to stack - Simply Surround (as well as 90% of other plugins) works well with the dspstacker from Muchfx2 stacks about 10%. - September 12, 2001 by Kenneth Oransky

DAMM GOOD!!! - Great sound effect do just like it says it expands da Stereo , but in that way if ya computer is connect to like a DJ equipmente it make an other type of effect including of it , it make like an a sorround system but it doesnt disturbs out the bass like mainly surround system does!! - August 26, 2001 by Sebasti�n Holzapfel

DFX Has Nothing On This Baby - I have used DFX but i'm telling U, It has nothin on this. If I could I would give it 10 stars but the dam thing only goes to five. - August 13, 2001 by Steven Cox

DFX Couldn't beat this if it tried. - DFX has NOTHING on this baby, It sounds GREAT! and for FREE no less. Great job Sylvain! - July 25, 2001 by Kyle Lawrence

Not too shabby - I'm gonna keep this short and bittersweet. It slightly improves sound quality on my computer. It definatly could use some configuration options. However, it is free, unlike some other dsp plugins I know of, *cough*DFX*cough*. Plus it dosen't add ANOTHER window in winamp. - July 16, 2001 by Jesse Brown

it's sorry and i had better like the DFX - I think it is have no controls and it's automaticaly set to a perset........and i've had better - July 14, 2001 by al johnson

Super Expand.............. - This expander is Super Great!!!! If you just have 2 speakers for your computer. It feels like you have four. This is one great product. DOWNLOAD IT NOW!!!!! - July 13, 2001 by William Morrison Jr

Can not be serious! - What a childish approach to sound improvement. You can not be really serious, can you?? Check out some of the other plug-ins and compare and you shall see what I mean. Then, maybe if you study what they are doing, you may have a chance in the plug-in arena. On the other hand, why bother anyway?? Have fun. - June 28, 2001 by Paul Maier

ALL the way around... - I have really high end speakers, but this plugin makes my music sound even better, its like its coming out of the walls instead of the middle of my mointor! - June 27, 2001 by Kyle Lawrence

Too good to be true!!! - Adds AWESOME sound to my small computer speakers. I can't believe my ears!!! THIS IS A MUST!!!!!! - June 26, 2001 by h h

I can't believe my ears ! - Incredible, the music whirls around my head. In three words, simple - efficient - BRAVO. - June 22, 2001 by Dereck V. Dick

this freakin' rocks!!! - OUTSTANDING!!! Finally, MP3's sound like I always wished they did! Thank you!!! - June 22, 2001 by Claudia Dinkoff

It doesn't stack with other plugins - It adds a great deal to my files, but Much Fx won't load it. I read a review that says it works great with DFX or Dee. Not in my ZipCode. - June 21, 2001 by guillermo etcheberry

WoW!! - Even with my modified version of the Bass & Trebble preset, I can hear every thing now! As if I were at a rock concert!!! - June 20, 2001 by Douglas McKasson

Scroll no further. - I was listening to one of my favorite songs, and fired this baby up, and I was shocked! It was like hearing that song again for the first time! I tried this on headphones, small crappy speakers, and my Dolby home theater. It sounded great on them all. You should really try this for yourself! - June 18, 2001 by Edward Hunter

It's pretty damn cool..... - I really appreciate this one because I've only got two little computer speakers, but this makes it sound like I've got subwoofers hooked up to the computer!!!! - June 7, 2001 by Blair Carter
