Convert M4A to 3GA

M4A to 3GA conversion seems to be pretty easy to achieve, considering both formats are well-supported. Just keep in mind that any audio converters list only MP4 and 3GP as supported and this might be confusin for many users. If you need to, you can rename m4a to mp4 and 3ga to 3gp, which solves a lot of possible issues with this conversion. But modern software should recognize file types regardless of the file extension.
