MP3Converter - Video & Audio

As a songwriter perusing her passion, I couldn’t find any good converters. I tried this and it was good. . . Then two of my songs ( that sound fine in the app ) are always chopped in one part of the file when I convert it. It’s only one song but both acoustic and regular versions are like this. So basically I can hear the instrumentals that are in that place but the singing is just GONE for the first few words

❌This app does NOTHING❌ I have 3 video format from simple .mp4 (file size 60mb, 80mb & 110mb)(720p & 1080p) an to a hard to player video format like .mkv (file size 1.5gb)(4K) & .webm (file size 2.96gb)(4K)…results?= NOTHING. All the video show i try to convert has a straight wave line (which should be wavy to indicate a audio pitch) but for the .mp4 I see a video image clip but ZERO audio indication…the END GAME, you click the convert button (on whatever quality) an it just shows “ADS”😑 just “ADS” every-time I pick any format it just show “ADS” (I get a glimps it try to processing but NOTHING happen after a “AD” is playing).

I've been wanting to be able to download songs for ringtones, I even purchased a song from itunes which was a waste if I knew this was there. I wouldn't have done that!!
