First, a little background. I built several editing stations for my previous employer utilizing Declink 4k cards for both SDI output and Balanced audio outs.
All those stations ran Premiere for editing. After leaving that employer and becoming much more frugal, I have switched to Resolve and had an IT friend build up an edit system for my personal use. It uses the RealteK Nvidea sound card that came built in to the box.
I have been having all manner of noises (including anytime the hard drives were being accessed/and even when using the USB mouse wheel) from the computer hardware entering the audio. I found the majority of the problems encountered during timeline and source playback were solved by replacing the unbalanced cables between my mixer and powered speakers with balanced cables.
NOTE: The audio noises are NOT being encoded into the timeline and are mostly an annoyance when trying to know if the original audio has noise or is clean. Now, the only computer noise remaining is when I use the new transcription feature or other features that are drive intensive. As the hard drives churn I get noises associated with the platter access.
I would like to eliminate these noises as well. My question is how do I go about isolating computer generated RF from the power supply and drives, etc. from entering the audio output from the computer without spending a fortune on a high end audio board? I'm assuming the answer involves getting balanced audio out of the box to begin with.
I have read so many conflicting articles about inboard vs. outboard (ie. internal sound card vs. USB audio interface boxes) that I don't know what to trust. I am open to all suggestions.
