Hello @GiorgioFabbro, thank you for the clarification. Following my employer policy, I might not be able to publish source code on a platform different from our github facebookresearch. I should be able to push a new version of Demucs based on my findings in the competition on the Demucs repository (on Github, facebookresearch/demucs) and push a solution on your gitlab that mostly make use of that code. You did not tell me on the timeline for open sourcing. Depending on which solution I chose, I would need more or less time to obtain the approval from my employer. I will also be in vacation starting on Friday until september, so timeline is quite important for that too.
