First of all, this is my first time to write this kind of stuff

This dll is used to produce treble and bass basically.
The "extender" means for some frequency, it will reproduce the frequency and extend further above the sampling rate.
Treble may be look similar with "noise sharpening" one but they are totally different. (Especially in the equation I use)
For the bass part, I have no experience in making it, but I would also like to receive some comments.

Please use PPHS resampler at 192kHz and this foo_crystalizer after the resampler for the best result.
And I only have 2.0 system (also the soundcard), so I can't test the stability of channel with more than two, please report if there is any problem.

Works fine now

It seems that it processes the sound even if sliders are set to min. and then sound is attenuated
I don't use bass, but trying it looks like limiter is needed after using it - every step introduces ~ +2dB
Treble also sounds very different then noise sharpening, and when treble is set to 2/5 the sound seems the right volume

I've set it to 1/5 or 2/5 for treble and 0 for bass

Thanks

Thanks for your testing and comment~

I don't know the user need which level of treble and bass in their sound system
so the slider is a little bit large in range, actually I also use 1/5 to 2/5 for treble as you do~
I discovered that adding bass or treble will produce signal that exceeds the limit, so I attenuated the original signal.
Maybe later I will put a slider bar for user to change the volume of original signal.
The idea behind the treble sound is different from noise sharpening, but you may say that is more advanced version which involve something like taylor series
For the bass, I just use low pass filter and doing little bit modification

v1.2 updated

remove bass part, seems no one like it
the original signal is now not attenuated
this dll will not consume much cpu power when compare with previous version
using of resampler with 192kHz before this dll is recommended
later version will focus on different type of treble sound....
