i should add i was using the 1khz offset tone for the offset adjustment, i know i didnt explicitly state that, but i do know how to use the tool. It works with usb. I also already turned off sound check and the equalizer in apple music. Of note my phone had sound check disabled the whole time, but my pc had it turned on, so its possible when i added the songs to the library on my pc sound check modified the file to even the gain. I will have to try it now that its also disabled on my pc, especially if i dont find anyone else with the problem. I initiatially thought this should be a wide spread thing
