If you get rid of iTunes, you can use third-party iPhone transfer software to transfer ringtones to iPhone after converting iPhone voice memos to ringtones. You can use iTunes to do that, but you should pay attention to the auto sync of iTunes, because it’ll erase the available files in iPhone during the syncing process. Now you can sync the M4R file to iPhone as a ringtone. Rename the voice memo and change the file extension to. Right-click the chosen voice memo again, and choose Show in Windows Explorer.ĥ.
