When I actually tried it with Wave: 3, the basic noise suppression power was strong and the effect of 'NVIDIA Broadcast Noise Removal by Elgato' was not so much, so I summarized the state of video playback where there was a clear difference. .

The sample used was `` Demon Slayer: Kimetsu no Yaiba '' Bizan Ropeway Guide Announcement @ Challenge by Tanjiro Kamado & Zenitsu Agatsuma & Inosuke Hashibira! Machi★Asobi vol.3 '. This is a video shot and recorded of the announcement sound flowing inside the gondola of the ropeway along with the scenery outside. In addition to the operating sound of the ropeway 'going gooun ...' so that it overlaps with the announcement, the window is open, so you can hear the wind noise.

Below is a video of the actual noise reduction at 0%, 75%, 90%, and 100%. Noises other than announcements are gradually suppressed, and when it reaches 100%, even the sound of the departure bell disappears.

I tried it in various other situations, but it is very good at removing periodic sounds such as motor noise, and it leaves the human voice clearly.

However, when I increased it to 100%, there were times when it seemed that the human voice was partially cut off, so it seems good to set it to the point where the noise is removed to the extent that it does not get in the way.
