Little experience with Audacity, but...

Try to cut off above 6khz (that's far above the mark/space signals).
You probably have to experiment a little. Let us know if this works
A backward compatible ATX sounds fine to me as long as the whole thing is documented.
I wouldn't call ATX, PRO, ATP or any other derivative format a "preservation format". It's best practice to save the raw source and have several "publication formats" e.g. for emulators.
Some ED protections only contain (a lot of) double sectors. I once experimented with it and got 30 full sectors on each track.
IMHO it would still be nice to have an open documented image format. It could be based on the ATP proposal or something completely different. As long as it's documented and open source it would make me happy

Hi Voy!
All credits go to Farb and others.
I didn't contribute any disk images here ( yet?).
Maybe you can get a 96tpi drive somewhere? Or i can send you one if you like.
It would be great to have all those Polish titles preserved! :-)
Friendly greetings,
Freddy.
The question remains, who needs it?
Personally i never used/needed FP on the Atari and i try to avoid FP in general, but i'm probably the ignorant exception?
IMHO only the raw images are the preservation formats. ATX, ATR, PRO and others that are extracted from the raw image, are user/emulator formats. Both are important ofcourse, but i rather loose an extracted on than the raw one.

We focus on real (physical) collections and all kinds of variations (box, labels, dumps etc.).
It would be good to relate the original owner and original copy to the digital dump.
I hope you're also recording that info Farb?
Would be nice to exchange ideas about our preservation process.

Let me know if you like to have the source code, i'll dig it up

Hi Farb,
Nice to see you're still working on this subject!
You know we have the same goal
We already have metadata and storage infra in place. Will support both Kryoflux and Supercard Pro raw images.
Let's join forces and talk again, ok?
Regards,
Freddy.
