I used the software MKVtools to delete an audio track successfully from a MKV file that has two audio sources. The software is very simple to use, however, it does a really bad job when it comes down to it. The audio isnt exactly deleted off the original file, instead it reads the MKV file, sees that it has 1 video file and 2 audio tracks and recreates it via a new MKV file minus the unwanted track. Normally this wouldnt bother me except its doing a really crap job at keeping the desired audio track in pristine condition. Could you kindly please list and / or link other software that would do what I am looking for. Thank you in advance.
