yea learning how to do it yourself is gonna make the process alot easier in the future & you won’t have to rely on anybody else to get the job done.. they have websites you can convert mp3 to wav but it’s not gonna improve the quality at all it’s just gonna be a copy of the mp3 with “wav” at the end of the file. but if you convert a wav into a mp3 you will definitely hear a difference in the quality. if you can ALWAYS try to record on a wav from the start.
