M4a is basically a variation of the popular mp3 format and works just fine across many platforms, while still retaining high quality sound and good compression. Otherwise you can just keep it in the current file format. If the file is m4a, aac, m4v, or otherwise, you can use iTunes to convert the song to MP3 format again. Now the MP3 has been trimmed down the section of the song you wanted.
