Or use Bdroid's Audio Media Converter (Tunr off the wifi for no ads,) I recommend this app as this is actually trustworthy and I use it for my music from .wav to .aac
Oh, alright. You said that it worked albeit mostly. Mostly? The app works just fine, but changing the title just converts it to another format (some audio quality loss may occur).
Good for you. I strongly advise you to stick to mp3 for alarms/ringtones. .WAV is the best, yes, and .AAC is better than .MP3, but they may put an extra strain of your phoneβs hardware, not to mention the RAM and battery.
