Audio Import, Export, and Compression

I am trying to understand how Storyline currently handles audio.

In the past, our process was to record wavs outside of SL (so we could edit with no degredation), import into SL (which would keep the files as wavs), and publish with the standard settings (which I am assuming encoded as mp3), and it sounded acceptable.

As of a few months ago, we started noticing that the audio sounded lower in quality, especially on male voices. We then noticed that SL was converting the wav files as MP3s upon import. I am assuming this happened October 29, 2019 (Build 3.33.20625.0), but don't know for sure.

I know we can use mp3 files and turn off the compression to control the quality of the sounds, but this will cause us have to re-encode the wavs as mp3s and then store 2 versions of the files (a wav in case we need to edit, and the corresponding mp3). And then we'll need to turn off the compression on each slide that has audio. This, of course, will add extra steps / time to our process.

Is there a way around this? Is there a way to still use wav files and change the encoding / compression of the wavs so they sound better? Upon import or upon publish? Or something else we can do to keep the process streamlined? It's fine if not, but if there is something else that can be done I'd love to hear it.

Thanks all!
