The same saved music export sounds noticeably rougher on one pair of headphones. On the desk speakers I barely notice the passage, although the room is not particularly quiet. I do not want to edit the file prematurely. The file is identical in both cases; I have not made a second encode or downloaded another version. A search brought me to <a href=https://musicartifactcleaner.top>ai audio artifact removal but I would like to rule out the playback chain before treating this as a repair problem. I will start by checking the playback equalizer. Next I can listen again at comparable volumes. Would borrowing another pair of headphones tell me more than inspecting a picture of the sound? A second playback app is available too. The aim is to locate the cause first. What would you investigate after those checks?
