We've been researching an audio denoiser for music that we will present at the AES conference in October. Description page: https://tape.it/denoising

We'll also publish a webapp where you can use the denoiser for free. Mail me if you want beta access to it (email in profile).

It won't be open-source though, although the paper will of course be public. It will also only reduce noise, and not reconstruct other aspects of audio quality. However, it can do so on any audio (in particular music), not just speech like Adobe Podcast, and it fully preserves the audio quality. It's designed exactly for the use case you want: to make noisy recordings sound professional.

Are you sure the demo sound files are correct on the website? Couldn't appreciate any glaringly obvious differences between the original and denoised with studio grade headphones here. Or, the originals aren't noisy enough.

denoising seems to fail in the guitar and vocals example

Can you clarify where it fails? It's designed to remove stationary noise only, and removes it very well in the guitar and vocals example.

Generally speaking, if you have other sounds that you don't want in the audio, we don't remove them - it's hard to decide from a musical point of view whether you want a certain sound or not. To give an extreme example: a barking dog probably doesn't belong into a Zoom conference, but it may very well belong into your audio recording. Removing such elements would be a creative decision.

The guitar and vocals example has certain clicks in the background that we don't remove - but the stationary noise is gone. Existing professional (and complex) audio restoration tools like iZotope RX don't remove those clicks, either. It's a conservative approach, sure, but in return you can throw any audio at it and it always improves it.
