Converting MP4 to M4A: what to know
MP4 is converted to M4A to keep only the sound of a video in the format Apple devices and iTunes use: music, a podcast or a lecture.
The sound in an MP4 is almost always AAC, the same codec M4A uses, so with the default settings the audio track is copied without re-encoding: fast and without quality loss. If you change the audio settings, such as the bitrate, the sound is re-encoded. For an iPhone ringtone, choose the M4R format.
