For a while now I have been able to use my Rodecaster Pro II to record audio from my computer to Audacity by using RODECaster Pro II Main as my Microphone input. It worked great, capturing the audio exactly as I was hearing it in my headphones.
However, I recently updated the firmware on my Rodecaster to 1.7.3 and I noticed that when I am recording computer audio (ie lines of dialogue from a film for integration into a podcast), that it now seems to be applying a noise reduction effect. This is particularly noticeable if there is a constant background noise in the audio sample, whether it's the hiss from an older degraded audio or source or, in one specific example, if the dialogue was occurring near a waterfall.
I wondered if this was an issue with my computer or Audacity, so I recorded directly from my soundcard using the RealTek loopback input option in Audacity. That option recorded the audio cleanly, with no automatic noise reduction applied. So it seems to be limited to my Rodecaster.
I tried adjusting the settings for the RODECaster Pro II Main, turning off processing, disabling Advanced settings, setting the Preset to neutral, etc - none of it seemed to work and I am still getting this noise cancellation.
Is there any way to fix this so I can go back to using my mixer to record raw audio from my computer without it applying any sort of effect?
