I generated a 1kHz tone and applied the PKHarmonics. I see that it took some effect, mainly amplification, but when I look at the spectrogram of the processed file, I see no harmonics. I applied similar settings as above to H2, H3, H4.
This is the spectrum processed file:

Then the plugin must not be in the audio path or not enabled. Here's a loopback capture over a digital device:

And here are some extra harmonics:

JRiver Media Center v28.0.49 (64-bit) - DSP - PKHarmonic 1.02.png


It sounds better with the VSTplugin PKHarmonic 1.02 and H2 and H4 only (well below what is considered audible, -90 dB)

Hi Paul,

crashed on Windows 10 while installing C++ Redistributable (Reboot without notice). Came up fine afterwards. Otherwise runs like a charm. Many thanks for providing this little gadget.

Let me know if you need more information regarding my system.

Rgrds,

Mark

An experiment:

Joan Baez - Diamonds & Rust (1975), remastered with something of EQ, WAV 32/96

Better sound with PKHarmonic again!

What were your controls for determining "better sound"? How did you do the level matching and double blind?

With PKHarmonic the volume is higher so you have to lower it to compare, which is what I do.

My ears, which are used to hearing excellent recordings, mainly without electronic or computer instrumentation and with a large dynamic range.

Since this thread began, I have managed to further improve the sound of my second system by optimizing the W10 better. I did not use PKHarmonic for a long time because I made it sound better without it. It has caught my attention that with harmonics of such a low level I notice the difference!

With orchestral recordings I always preferred without harmonics, however now I also like it with the VSTplugin activated and with that configuration.

In other people's audio systems I have always been unable to notice differences, even between MP3 vs FLAC. But in both of my systems always.

IOW, no controls. Peeking. Not using your ears.

Why not? If the difference is appreciable, matching volumes, there is something. When I am not able to appreciate differences I also recognize it.

Anyone can try to verify it for himself, with a good recording, mainly acoustic instrumentation, without spending a penny. First with H2 at -40 dB and go down ...

Or you can build Nelson Pass 2nd Harmonic Generator

I think PKHarmonic is a simple way to try if you like monotonically decreasing harmonics.

BTW, I can hear the difference with Zoom too. All sounds go to JRiver MC thanks to the WDM Driver (a virtual audio driver). And browsers too.

I like more the voices without PKHarmonic (Zoom, Chrome, Firefox... ). Yesterday with the new YouTube video from Danny Richie: So, you want a GREAT Speaker? Tyler Acoustics. Voice more clear and intelligible without PKHarmonic.

Just now,

Better without PKHarmonic, as expected.

Bullshit excuses for making claims without basic controls are bullshit. Do better or find a place more amenable to fairy tales and woo-woo. This is Audio Science Review.

When the difference is evident one does not need to do blind tests. If it were a scientific paper then yes, but this is a an audio forum.

Repeated aggressiveness is not the way to go.
