What I particularly like about the Descript version (though it is overdone as mentioned) is that it reduces or eliminates the pesky S sounds and P sounds (called sibilances and plosives) that you get when you talk into a microphone and you're not perfectly distanced from it.
I haven't found another app that reduces or removes these.
Its machine learning powered noise reduction + compressor + eq + normalize combo effect. Works ok. Results in quite a bit overdone “studio” sound. I think trend in mixing is leaning much more natural (less tweaked) nowdays. But for no work it might be impressive. Probably works in internal corpo presentations well.
