What a shame that after paying >$500 for my iPad Mini Retina .... I have to wade through AUDI ads before I can convert an MP4 recording to MP3. I dunno ... now that I am in my late 7os ... It may be time to kiss this wonderful APP goodbye and buy my own recorder -- or alternatively AGAIN risk sending my MP4 recordings offsite for conversion to MP3 Otherwise, thIS APP itself is outstanding!
