Hi, i have a problem here that is nagging me for 2 hours straight now: If i convert a mp3 file via itunes or any of the many ringtone apps to *.m4r and select the ringtone after synchronizing, the sound quality of the custom ringtone is x-times worse than the original file. i have renamed my file to *.m4a and added it to the music library on my iphone to test if my file was bad, to my surprise the file sounded just perfect with applee music via speaker and headphones. but if i play back the very same file via settings or call my own iphone, the file sounds totally crap, muffled (again via speaker and headphone) and just cheap. i could reproduce this behaviour on my 4s, ios 9.3.5 5 and 5s with 10.2.1 and 10.3.1 and 6 with 10.2.1 i have revorded a sample via the headphone jack plugged into line in on my pc. music playback and ringtone level were both set to max. http://s000.tinyupload.com/index.php?file_id=00409699521395766437 ios seems to play a soundfile differently when it's set as ringtone. question is, is there a way to make custom ringtones sound decent on ios?
