While audio restoration works wonders on most recordings, severely damaged ones may have their limitations. However, skilled engineers can still sometimes perform miracles on seemingly irreparable audio.
The time required for audio restoration varies depending on the condition of the source material and the complexity of the issues. It can take anywhere from a few hours to several days for intricate restorations.
The primary goal of audio restoration is to maintain the authenticity of the original recording while enhancing its quality. The process aims to minimize alterations and preserve the artist’s intentions.
