The Resampler-V plugin uses the SOX and the SSRC libraries.
Those libraries are much more extensive then what you can put in the FPGA.
Also the Resampler-V plugin uses the much larger processing power and memory of your PC.

But when you feed 384 all user editable filters are skipped - so nothing to compare to.

Yes that's true, but I have no desire whatsoever to compare. It is too obvious, no way back for me.

Danny, take care of your ligaments...just today a friend destroyed some in the knee skiing.
It might just be a different filter. I don’t doubt that you believe it’s better though. Would you care to try 1.19 linear vs partypak bank 2 EQHQv5 apo? The new stock filter has way more bass and maybe a bit “smoother”, can’t say which is better but partypak is theoretically sound. You can update filter by “download” in umanager and power cycle.

Yes, the filters are then defined and processed in the Resampler-V plugin.
You can compare the different Resampler-V options:
sox, ssrc, minimal, intermod, linear, pass and stop band, SB attenuation

Okay. I’ll try it with newNOS in the afternoon. I would love to put my Xeons to good use

Question, what’s the SOTA with SOX libraries, if a comparison can be drawn with the the filters we have in the FPGA

So what "filter" are u using when producing 384 kbps by the plugin.

Aren't u just up-sampling? Why a filter?

Yes, I'm upsampling.
With filter I meant the options I can select: minimal, intermod, linear, pass and stop band, SB attenuation

I have the Dam1121, so I don't know how the software and filter situation is right now. AFAIK I have Bambadoos filter pak installed.

Why you would one use anything else than linear is beyond me as the other stray away from the sampling theorem.
