MKVExtractGUI-2 is an alternative graphical shell for MKVToolnix, or more specifically for the module responsible for extracting audio tracks from MKV files. It also works with other popular video formats, but in 100% of cases the developer guarantees successful separation of audio and video only for the Matroska container. In addition to extracting the audio track, this tool can also extract subtitles, chapter lists and other "attachments".
Using MKVExtractGUI-2 is incredibly easy. It is enough to specify the path to the MKV file to the program, after which it will almost instantly analyze it and make a list of the tracks found. The list will include headings, type (sound/subtitles), format, serial number and, in some cases, a brief technical summary. All data you need to extract from the container should be ticked and the Extract key should be pressed. By default, extraction takes place in the folder with the file itself, but nobody prevents you from changing the path of saving by yourself. By the way, MKVExtractGUI-2 supports batch mode, in which it extracts all available data from multiple MKVs.
Among other interesting features of MKVExtractGUI-2 we can note the possibility of choosing the format of the document, in which the information about the chapters will be saved. XML (default) and OGM are available to choose from. During the extraction process, the program does not load the processor and RAM too intensively, and this process usually lasts no more than a couple of minutes.
