Adobe Audition (aka "Cool Edit Pro") from BITD I would even help on such a project, I have DSP and audio editing experience... While I'm dreaming, Ableton too.

Desperately.

Also, although it affects me far less, I don't mind paying the closed source penalty, woudln't it be great if Mathematica and MATLAB were open sourced too?

I would love to see an open sourced steam. I’m sure there are a lot of challenges to making that happen though.

I want a free/FOSS version of Livestream Studio to do live events.

OBS just isn't cutting it for me.

Zonal OCR software that can do data extraction as well as the stupid expensive offerings from ABBYY and Nuance.

Can you elaborate? What is the use case?

Extraction from semi-structured documents. Reqs:

- No absolute element positions

- Able to handle a reasonable amount of skew

- Able to handle photographs of documents (e.g. mobile)

- Excellent support for repeating groups/elements

- Around 95% accuracy without human verification

Similar to the other comment you received, I've also been working on some of the math necessary to do such a a thing! I have no idea how it would be productized there's so many things out there that do "good enough" jobs... One of my ideas was to extract structure from motion and use that to deskew and align..

(Can I also have a datadump of candidate files for testing?

Interesting, I have implemented some version of the above in the past (albeit not in an opensource/free solution).

If you have a specific document/data extraction need in mind, you can email me a sample and I will let you know if I can help.

IDA Pro

This is the best answer so far.

I would love to see an open source version of Google Play Music app for Android. There are a bunch of minor things I don't like about the application but can't easily be fixed because there is no open source version.

Good(-looking) knowledge base software. Open source / on-prem solution

Like Confluence or Nuclino (nice UI/UX)

Sublime. I want to get rid of annoying popup asking to buy Sublime.

Then buy it. The idea behind open source software isn’t to provide software for free but to provide free software.

Windows stuff.., like paint and notepad

Hmm. Everything?

Good idea. What would be your favorite?

Intercom

Google Sheets...

Since Sheets is already free, I'm thinking you said this because you'd want it open sourced. Curious about why you'd want it open sourced.

It's the most widely useful online service I know of, but building in it means vendor lockin and privacy problems. Collaborative spreadsheets seem like a building block of networked organizations and it would be great to have that under control (free as in freedom).

GitHub

GitLab fills that to some degree...

Windows kernel and drivers.
