How to convert M4A to MKV?

About the formats
Audio/Music file formats
M4A files store audio using the AAC codec. M4A stands for MPEG-4 Audio. It is very similar to MP4 with the difference being the lack of a video/subtitle track in the file.
Video file formats
MKV files are MatrosKa Video files. Like the Russian Matryoshka doll, which contains multiple smaller dolls nested inside each other, the MKV format can contain multiple video, audio, and subtitle tracks inside a single file. This makes it convenient to have one video with a number of audio and subtitle tracks in different languages, all inside a single playable file.
Common questions about converting M4A to MKV
Can I convert M4A to MKV in bulk?
Yes, MConverter supports batch converting of multiple M4As to MKVs simultaneously. You can even drag and drop folders containing M4As to convert to MKV. Pasting M4A files and folders copied in the clipboard also works: use Ctrl+V.
