sometimes when im recording the audio comes in to low . it would be nice to have a audio auto gain to less say +6 dbs if you turn in on for thats audio input
What audio are you talking about, PC or Mic?
In any case, you can just increase it afterwards with no effort really, as you are going to Encode it in any case.
If you are Encoding during Capture then the only thing you can do realistically is to increase the volume on the PC or Game.
You normally need to have much higher volume to capture it at the same sounding volume.
I pretty much Capture at much higher than i play at, but i reduce the volume on my Amplifier so it doesn't affect me. The same can be done with any kind of volume control on anything after it has left the PC, and thus doesn't have any affect on the Capture volume.
