Please try it - no DC blocker - be warned (or happy)

Damn this filter sounds really good, it's almost indistinguishable from the poly-sinc-xtr filter that i upsample to via hqplayer where processing power is not a concern, the closed-form filter though is special especially in soundstage when using R2R dacs.


Good job on the filter TNT 👍

TNT can make this also, I supplied the text file of the last one, just NOS needs updating to NewNOS and the 44.1 F4 replaced. (unable to find the newnos constants and how they differ as someone made sure to delete those useful files that were once in their posts)

But are these Paul filters available as text? As I'm the only one here who seem to have original work to contribute, maybe it would be fair if I could redistribute what is already in the "public domain". I would be happy to share my filter, but would like to keep my source file by myself for some more time. But as I don' have or use any of the Paul filters, I need have access to them in order to do a .skr file.

Okay, happy with this one. The older NewNOS was in an older format so I kept the ones that oneoclock had which was updated to the newer format. TNT please do your magic and update F4 and its FIR2 if needed. Thanks again, looking forward to trying this.

If you send or pont to files that you would like to see in a new filter-pak, please indicate what position (F5-F7) you want it in. I dont use NOS or any other non-linear filters, don't know anything about it so you must be very clear what file you want to go with what Fx :-)

So this "shared filters"... how does it work. Is really the same filter used for 2 diferent Fs?

I will do it like this:

dam1021,44100,8,1004,1999,8
04 Linear Phase TNT2, 44.1 Ksps, 19,4 Khz - 0.3 db, 22.04 Khz -163db

dam1021,48000,8,4,1999,8
04 Linear Phase TNT2, 48 Ksps, 19,4 Khz - 0.3 db, 22.04 Khz -163db

0.0000000000199589610540556
0.0000000000183149373464365
0.000000000014025867195505
...

(I will do 4k version later!)

Hope it will be OK.

I will play it, but...

Is there any volunteer that can test run my file before forum upload?
