MKVToolnix is an excellent and innovative free licence programme orientated toward the editing of MKV formatted files, being more compact than the OGM multimedia container and with the possibility of editing the sound, getting a superior quality in respect to the size of the file.
This wonderful programme is characterised by being open source, where any user can determine what improvements would be necessary in order to get it to work better.
You could say that the MKVToolnix is not a simple converter or file editor, but that we are facing a powerful container where you can make use of different audio file formats such as Ogg Vorbis, AAC, MP3 and AC3 etc.
One of the main features of this application is that it supports video streams derived from AVI and OGG files, as well as Vorbis audio streams encapsulated in OGG files, among others.
