I don't know if anyone else has experienced this, but when I, using foobar2000, make MP3s with the DSP turned on, I get a ton of artifacts. It seems to happen if there are two instances of the plugin being used. I've figured out a workaround which is: 1) Don't playback music while converting with the DSP on. 2) Check "don't reset DSP..." (This prevents foobar2000 from opening up two threads since I have an AthlonX2.)This is a great DSP and I like creating MP3s with it since I only use MP3s with my portable. Perhaps somewhere down the road someone can take a look at this. Thanks for all the work!
Your assumptions are correct. The dsp modifies the audio data and then that modified data is encoded. The dsp is subtle by nature and only meant to relieve listening fatigue. As a side-note, I also apply replaygain when I make mp3s to help reduce clipping problems.
I made a ladspa plugin based on the bs2b library, so linux users can enjoy it as well in the future. It will most likely be included in the next tap-plugins release. (it's not my set, but i figured that would be the easiest way to get it to spread) It's currently in cvs if anyone is curious.
There is no right order for these two plugins as they serve the same purpose. You should only use one of them at a time.
Thanks a lot for this excellent plugin! I read earlier in this thread about a VST version of this. The link, however, doesn't work...

There is a VST Plugin that HOST Winamp Plugin.http://www.hydrogenaudio.org/forums/index....mp;#entry497444It's still a little bit buggy. but it's work.
what the slider "crossfeed level" actually does (amplifies degree of processing? narrows the soundstage by using different values in the same formula? uses a different logic altogether?)what the "easy" on/off does and how this affects each of the three crossfeed level settings
I guess what I want is a high level explanation in binaural terms.
lol thanks Boris but that was NOT noobish!I'll try to look over those references but, although they all appear to be very interesting from a technical perspective, they do not directly help me with my questions.I am sure I speak for many interested users of your plug-in when I say that you need to provide a concise and easy-to-understand high level explanation of what the settings mean. Not everyone has hours of time to study the issue in detail - and many not the ability in any case.My own understanding of cross-feed in general extends to something about mixing a bit of left into right, and vice versa ... I do know that binaural recording is very difficult on account of the variance between the shape of peoples' heads and ears, so perhaps you could recommend BS2B settings for different applications.With respect, answering the Q by way of referencing circuit designs and dozens of technical white papers is not helpful. But thanks anyway!
Crossfeed level min : You're in a room with speakers placed almost directly left and right of you (60 degrees azimuth).med: You're in a room with speakers at 10 and 2 'o clock.max: You're in a room with speakers at 11 and 1 'o clock (30 degrees azimuth).
Easy OFF: Mix the left and right signals normally. Result is mild treble rolloff.Easy ON: Highgain boost or "Easy on the mix, baby!" Not as much treble rolloff.
Now, in 50 words or less why would mixing the channels "normally" result in a treble rolloff? And, following, why would anyone want the "Easy" option to be anything but on?

There is not reverberation.

I set R1a to 200 ohms (40% of the original value) (my note: original one is Linkwitz version).Since all recordings are not the same, I added a "PERSPECTIVE" switch (S1) to customize the processing with an alternate R1 value. At R1b = 150 ohms, the low frequency separation between channels goes up to about 10dB and the overall output increases by about 2dB. Toggling from R1b to R1a, the soundstage appears to move further away (lower output, more narrow soundstage, slightly softened highs)."Anyway, why asking what someone hear? Yours feelings is more interesting.
