The next choir rehearsal needs a clear practice recording. The melody and entrances matter more than a polished production, but I do not want an odd texture to distract people learning their parts. One sustained phrase draws my attention. My first check would be ordinary listening at a comfortable level. I found a page about remove ai artifacts from audio while looking for language to describe the problem. The original recording is still my only reference. The timing of each entrance needs to remain easy to follow. The clarity of the sung words deserves a separate check. An isolated passage would keep the first comparison manageable. The singers will use different playback devices at home, so a texture that seems minor on my headphones may deserve a second opinion before I distribute the guide. What would you check first in a rehearsal guide like this?
