Which crossfeed plugin do you suggest?  I did a quick search for a Winamp DSP, but I'm not sure what's best.

Does some sort of crossfeed "filter" exist that crossfeeds all audio in Windows XP?  That would be optimal.  I'm sick of an unnatural (unintended) soundstage in my headphones.

Since the crossfeed effect is a rather simple one, I'm guessing that most plug-ins will be pretty similar. A quick search for "winamp crossfeed" turned up this: http://www.headwize.com/projects/kopjov_prj.htm but it doesn't seem to be working properly. If you found different ones, just try them and see whether they fit your needs...

[SmartOne]

Now I'm not sure if crossfeed really does what it advertises or if it simply degrades the quality.

Tried those two with default and preset settings.  I like to hear the bleeding edge of sounds, and those seem to muffle the sound (especially lows.)  Also, there's an annoying tiny pop when starting a track or skipping with both plugins.  This could be caused by the wrapper...?  Will keep testing with my HD595's.

By default, the Winamp DSP wrapper will pass 16-bit sample data to the Winamp DSP plugin, as that should be supported by all of them. If a plugin supports higher resolutions, you can set it to 24/32-bit in the wrapper config, for higher quality. Note that if you have multiple DSP plugins active, the final quality will be limited to the lowest resolution amongst them, so there's not much point setting one to 32-bit while another is 16-bit, for example.

If you happen to have source code for what you want to do, the best thing (for quality) would be to create a native XMPlay DSP plugin

Thanks, I have both set to 16-bit and only use one crossfeed DSP at a time.  It would be silly to use more than one.   (I meant skipping with EACH plugin.)  I'm already hesitant about altering the audio at all.

What do you think causes the tiny pop/crackle?  That alone kills the possibility of a crossfeed DSP as a permanent fixture.

Have you tried (un)ticking 'Reset buffers' in the wrapper configuration?

[SmartOne]

I think Reset buffers fixes the cracking problem.  It's very hard to tell without a nice and quiet listening environment.

I especially like the Bauer stereophonic-to-binaural DSP.

Maybe someone or Ian can implement it directly in xmplay?
The website describes the whole theory and the DSP is really good for headphone use.

[SmartOne]

I've decided I don't like artificially enhancing the audio.  Sounds worse anyway.

[Tron04]

Even though the stereo chrossfeed effect plugins are doing kind of opposite.
They do more "de-enhance" the audio, so it does not sound so artificially over headphones.
It's more like a naturalization.

why if I'm using bs2b plug-in, the settings on "auto-amp reduction" is always on the +0.0 value? so that the audio clipping is still occur

So you auto-amp is set to 'reduction'? That should avoid clipping of the output, but clipping might occur in the DSP chain. Could you remove the bs2b-plugin and check whether the audio clips if the auto-amp is set to (1) 'reduction' and (2) 'off'?

[Ian @ un4seen]

Winamp unfortunately doesn't support floating-point sample data, so it has to be converted to integer (and possibly clipped) before being fed to Winamp DSP plugins. Auto-amp won't be able to help avoid that clipping as it comes into play after the DSP. But here's an update to try, which should help...

   www.un4seen.com/stuff/xmp-wadsp.dll

It adds a "Borrow bit for headroom" option, which takes the lowest bit and uses it for an extra 6dB of headroom instead, ie. the sample data can be 6dB higher before it clips. That does mean that the quality will be slightly reduced, eg. it could be 15-bit instead of 16-bit, but if the DSP plugin supports 24/32-bit (as "bs2b" appears to), then the lost bit won't make much difference.

[reinhart]

Thank for updating the plug-in. I think clipped sound is worse than lost small amount of bits.
