Windows 7: Can I delay the left or right channel by a few milliseconds?

Changing the direction of the speaker (ie; off axis) will actually do more harm than good. One will lose detail and increase or decrease wall reflections depending on how and where it has been pointed.

Sound level will decrease by 6db for every double the distance the listener is from the source. So, if the OP was 1.5m from the right speaker, his left which is now 3m away will be 6db down requiring 4x the power to achieve the same volume as the right. This is just a very simplified example and does not take into effect reflections from the walls, ceilings and floor which will have a greater impact than just changing the delay (changing the delay does not rectify reflections just makes them nonlinear).

Amireldor; I suggested Foobar because its free to try and its fun to toy with. Its a pretty powerful media player if you can get around the whole DIY feel of it. But if you are serious enough about sound reproduction, adding delay will only correct the time in which direct sound will hit your ears. It will not correct the differences between amplitude or reflective sounds. Having your speakers of equal distance from both their reflective boundaries and your ears will create a predictable environment in which you can work with using acoustics and or DSP equalization.

The human ear will never hear a m/s or several m/s difference.
That's what I was alluding to when I mentioned the delay problem at rock gigs in football stadiums. Any delay due to speakers at home being 1.5 metres apart is imaginary IMHO.

Actually, the human auditory system can detect delays as low as ~0.6 milliseconds. This is how we localize sounds. A single sound source that is not 0 or 180 in front or behind the head will produce a delay to the furthest ear which is easily detectable. Of course amplitude and frequency will also play a part in this but to say the human ear cannot detect a millisecond of delay is not true.

Those of us with tinnitus welcome some deviation from the hissing and 10-pound crickets in either or both ears.

You had to remind me and now it's louder.
