MPEG-4 audio (M4a) files are encoded using the Advanced Audio Coding (AAC) or Apple Lossless (ALAC) codecs. They are recognized by the iPod personal audio player, but not by other MP3 players. ITunes and Free M4a to MP3 Converter are two software programs you can use to convert M4a files to the MP3 format. These programs can convert multiple files at a single time. The Media.io website can be used to convert a single M4a file.
