Looking for a careful workflow for small audio artifacts

I help a community archive prepare old concert recordings for private sharing with former performers. One recording has a lovely room sound and an expressive singer, yet several quiet passages contain small digital chirps that pull attention away from the music. I want to improve listenability without polishing away the atmosphere that makes the recording meaningful. During my research I found <a href=https://sunoaudiofix.top>a brief repair guide</a>. It seems relevant, although I would rather hear from people who have restored imperfect live material. My question is how to set a sensible stopping point. The original ambience is essential. A controlled sample can guide the first decision. I can compare matching passages before processing the full file. The restoration should remain measured. Any change must respect texture. I need repeatable settings for future copies. A fresh listening pass may expose unwanted side effects. The audience reactions should stay present. The singer's voice must remain open. Each adjustment should remain easy to document. I will compare it at quiet volume. I would rather preserve a little imperfection than make the result sterile. How do you decide when a restoration has become too heavy? I would appreciate preservation-minded advice.
