I just noticed that the 32-bit version of the plugin is not useable with Foobar 1.6.17--when attempting to install, Foobar produces a "failed to load DLL, not compatible with this version of the Foobar SDK" message.  Any chance of making it backward compatible with the older SDK?
You'll have to ask Peter to back-port the API's. The message is generated by foobar2000 itself.
Fair enough, what @sveakul didn't know is that this component requires foobar2000 v2.0 (which is the first version to get a 64-bit version) and later

Also, I've added a window function called Galss (which I come up with the name of such exotic window function that no one seen before, not to be confused with Gaussian), which equals to "f(x) = (((1-1/(x+2))*(1-1/(-x+2)))*4)^2 * -(tanh(sqrt(2)*(-x+1))*tanh(sqrt(2)*(-x-1)))/(tanh(sqrt(2)) ^ 2)", which has higher sidelobe amplitude at close proximity to mainlobe than Hann window but with better sidelobe rolloff than Hann window to my own spectrum analyzer project and I've changed the Welch/parabola window to make it adjustable (for consistency with power of sine and power of semicircle windows, the latter of which falls into the category of exotic window functions since not many papers mention it)

BTW (assuming this component have window function set to Hann, which is the default setting), I've tested the mono vs. stereo audio and spectral leakage thing and I've found that opening this visualization component on mono audio before applying convert mono to stereo DSP afterwards shifts the position on the peaks and opening the same component on the stereo audio (or mono audio with the same DSP applied before the visualization window opens) have high sidelobes comparable to rectangular window

I would say that the equivalent would be to select and remove all tracks in the component list.
A context menu 'Remove all' might be added in next releases...
Thank you.
This is a Option of "Queue Viewer". I deleted "Queue Viewer" for TEST of "Queue Editor", but it seems to remain.

the seeking problem, within mp3
MP3 wasn't designed to be seekable in the first place. If you wanted that, you were supposed to put it in a container, and the MPEG-1 standard defined MPEG-PS for that purpose. Newer audio codecs require a container to function at all - for example, you can't decode a raw AAC bitstream the way you can with MP3 - and the container ensures accurate seeking for those codecs.

There's one popular hack for VBR metadata in raw MP3, the Xing header, but it only has 100 seek points specified in units of 1/256 the file size. That's not nearly precise enough for accurate seeking in an hour-long podcast even if your player supports it.

Care to share how you set it up? Trigger DSP chain presets? I used to have single VSTs set to launch on key presses, but that was with the previous wrapper and a long time ago. EDIT: What VSTs are you running besides Voxengo SPAN?
