Just discovered this newly released software SoundPimp that removes the crosstalk in audio and recreates the sound in the way the separation was in studio when it was recorded.
The effect reminds of the separation and instrument placement that one gets in headphones, but now from your stereo speakers.
Can also be used for movies to create "Surround Simulation" from stereo speakers and enhances multichannel movie surround sound.

The software doesn't add effects to the audio, it is a crosstalk cancellation software.

Several short demos on the web page with very convincing quality both for music and movie audio.

How SoundPimp works

Some explanation quotes from the web page.
Quote:
In the market, there is a flooding of audio-manipulative technologies for computer audio. Everything from equalizers to phase manipulators are available, some of them perceived perhaps as counterproductive in the long run due to artificiality, becoming ultimately a candidate for the off-button.

SoundPimp audio enhancer is not one of these, because it is based on indisputable and error-corrective algorithms with the dedicated purpose of so-called crosstalk cancellation. Unfortunately, crosstalk is nothing but a fundamental weakness of stereo loudspeaker systems.

The cause & effects of crosstalk, and the remedial operating principle of SoundPimp, are all easy to grasp. Follow the below outline of the recording and playback process, and it will be evident why SoundPimp produces a cleaning-up effect that is beneficial to most good-quality audio streams.

SoundPimp is based on High Definition Stereo (HDS), a computer based technology that offers enhanced sound quality compared to traditional stereo. It reproduces the sound of the original recording in a more exact way.

One of its fundamental building blocks is High Definition Stereo (HDS), a digital technology running live and working on the fly, actually examining the audio stream many, many thousands of times per second, sample per sample. Any error is promptly corrected applying extremely advanced intonation algorithms so as to restore the smooth and breathtaking soundstage of reality. The SoundPimp audio enhancer working principles are basically error corrective rather than manipulative. The result is an exact sound which is so much more obedient and true to the original than normal stereo, and this is why we call it natural sound.

The true potential of HDS can really be exposed when combined with top quality multichannel systems utilizing 192 kHz sample rate and 24bit sampling.

Having read their blurb, this sounds like a major source of distortion in the program. If binaural presentation were the norm, I could see value to the product for speaker presentation, but speakers are the norm, so this just messes with the engineer's final mix. As always, YMMV.

HAve fun,
Frank

Crosstalk between speakers is always different every time you pick different speakers, put them in different rooms, and put them in different places in those rooms. Crosstalk varies with the location of the listener.

Furthermore, over a wide range of values increasing and crosstalk has zero to minimal effect on sonic realism.

This appears to me to be yet another questionable product whose commercial success rests on the gullibility and ignorance of audiophiles and music lovers.

This stuff has been around for decades. Polk had them in their SDA speakers circa 1980s as did some others. Here is their white paper which has very similar pictures to theirs: http://www.polkaudio.com/downloads/tech-briefs/SDA_WhitePaper.pdf

And no, I doubt any 'audiophile' cares about such things. They are going after average joe as with other algorithms like this. You would go broke building $55 things just for audiophiles....

This program is complete junk. Its a repackaged filter in an awful GUI. They rely on freeware for the plugins and the sound is awful. It sound like the Arena setting on a 100 dollar AVR.

After reviewing the program and being apalled I asked for a refund which was refused and I got a snarky set of emails back. A first in my 10 years of hifi experience.

Trying to warn folks on the forums as the positive posts that led to the purchase were clearly faked.

AVOID!
