I copied the dll into the foobar's components folder and I tried your plugin for a while. Just some initial impressions: it works (it takes the music away from my inner head) but affects the sound a bit. The sound is somehow veiled, I miss some ambiance informations (maybe high freq. roll-off?) and with some recordings the soundstage is really too narrow.
I built a DIY headphones amp with the cmoy crossfed and the effect is more gentle and it has less drawbacks.
I think such a plugin is going to be very useful for everyone listen music through headphones, is there any way to make parameters user selectable?
Keep up the good work!
Thank you.

Yes, I know that Chu Moy's version is more preffered for some (may be most of) records. And I was make both Linkwitz's and Moy's versions by bs2b-convert.exe (see '-m' flag). I will make Moy's version in plugins by config window later.
Unfortunately, I has not hardware version yet, and I schedule to make Jan Meier's circuit, therefore I will glad to see comments about comparison of software and hardware versions and just a comments.
Thanks.
I will have compile Moy's version of fb2k plugin today and will post URL here ...just a moment.

I haven't tried anything yet so, if this request is silly just ignore it.

Feature request:

It would be the most useful if any DSP plugin could be enabled or disabled automatically by the content of a tag.

So, even when listening remotely from your PC (say, in bed) one could easily get the best setting for the playing track.

Of course there should also be a keyboard shortcut to disable it, enable it on track tag and enable it locked.

Of course. Why do you think it would be for 0.9, if there is no public SDK for that. Or were you hoping for a version for 0.7? tongue.gif

I tried it and I like it. Ways better than the other version, IMO.
It reminds me of the hardware version but for a reality check I must connect another headphones amp to the PC.
Thank you very much for this plugin. smile.gif

Thanks alot for this plugin! I listen to classical music at work on my IRiver with Shure E2s and none of the other crossfeed type plugins seemed to work well with classical.
A few questions:
1. When encoding to lame should I leave the bit depth at 24?
2. I also use vlevel before processing. Does volume level affect the effect?
3. Should I wait for the Meier version before rencoding all my music?

Why reencode?

1. I don't understand. All encoding is processed by double float inside bs2b.
And downbiting is done by external engine or audio formats only.
2. No, level does not affect the bs2b.
3. No, I mean of Meier hardware circuit that sound like Moy's version but is more simple RC circuit for high impedance input and output.

Note: bs2b just little down high frequencies level more by Linkwitz and less by Moy version cause of less by 3dB crosstalk of low frequencies by Moy's variant. Linkwitz's variant is more preffered if input stereo signal is less monoural in low frequency range, for example, if sound producer is mix bass viol in one channel only.

Thanks for your reply. I noticed with deep bass pipe organ the effect wasn't as noticeable with the Moy version so I'll try the other as you suggest. So far I've encoded several hundred mp3s and the soundstage is greatly improved for most of them. Thanks!! biggrin.gif

This is a good plugin, better effect than 4front headphones. I do find the highs lacking, or veiled (using moy version). will there be a configuration window later on? i like options ohmy.gif

Yes, I intend to do configuration window, but not so quickly.
There will be only one option Linkwitz's or Moy's (extra -3dB crosstalk) variant.

It well described at http://headwize.com/projects/showfile.php?file=cmoy1_prj.htm
see 'Figure 3' for quick refference.
All refferences are done in my documentation at http://bs2b.sourceforge.net/ or in bs2b package.

I just want to mention that this plug-in needs MSVCR71.dll (you won't notice if you already have it smile.gif )

In theory, there is no difference between theory and practice.

oops :-)
Thanks, but why project files uses /MD compiling flag in fb2k SDK?
Should I recompile SDK and bs2b plugin with /ML or /MT or /MD like now?

I has added two new test versions with high boost:
http://www.tmn.ru/~bor/tmp/foo_dsp_bs2b-h.zip
http://www.tmn.ru/~bor/tmp/foo_dsp_bs2b-hm.zip
Please comment it. If it usable I will add it to next configurable version.

Hi Boris,

Do the audio files need to be converted using the exe file before listening with foobar2000? Thanks!

In the options screen, does selecting "Low crossfeed" select Moy's version?
