Hey @mbolding3 -- love this work, and I'm excited to dive into your Pytorch compatible polyphase resampler over the next few days. Once reviewed, I'm thinking we add a new differentiable folder/module to the cusignal project. This way, to the user, you'd run something like:

cusignal.diff.polyphase_resample

I'd also not want to expose the diff.polyphase_resample to the core module, so cusignal.polyphase_resample always calls the non-differentiable version.

Just kind of brainstorming here!

CC @jfsantos, as we've chatted about this before. Would love your eyes on Mark's implementation.

Thanks for the comments @awthomp ! I'll be trying to wrap up the unit tests and integration in the coming week. Will be in touch.

@awthomp I'll have a look! Thanks a lot @mbolding3 for working on this.

@jfsantos my pleasure! Currently writing a handful of unit tests. Will drop a line when the fork has something worth seeing. (Soon!)

Install issues are slowing me down. Currently reinstalling Anaconda.

Install issues resolved. Will be next week before substantive changes are pushed to the repo. Thanks for your patience guys!

Alright sorry for the delay. The code is in a state where it passes some minimal tests and is worth looking at @jfsantos

Removing inactive tag; been a wild summer, and still need to prioritize testing this PR prior to merge! Thanks for the patience, @mbolding3!

I'm really sorry it has taken so long, but just a heads up I'll be testing this sometime next week. My application requires the backward pass to be fast but I can at least see if it works for now.

Thank you @jfsantos. I want the code to be performant. We'll make sure it works right first, then inject the nitrous later.
