Hi, is there any way to get more input gain, like +99db of gain ?

What? No. That's ridiculous. Also, this has been requested multiple times. I'm not going to do it.

To any young children reading this who want to have "fun" by screaming at each other on Discord as loud as possible: you can't defy the laws of physics. Making the input gain louder has a limit -- the audio signal clips at +0.0db and won't get any louder. And beyond a certain point, excessive clipping will lower the imparted energy of your audio waveform. (It will sound quieter.)

So: stop requesting I make Ripcord's UI worse so that you can learn that this doesn't work.

Or, at least, try it yourself using some external audio modifier software.
