Merging .AAC files?

killerteengohan · 5th August 2014, 09:16

I have 2 separate AAC-LC .MP4 audio files I want to merge.

Everytime I use the append feature in MKVmerge it throws the audio out of sync where it got appended at. If I had a 30 second audio clip and 21 minute audio clip and appen the 21 minute to the 30 second audio, it plays perfectly for the first 30 seconds then the audio goes out of sync the more and more the video goes along after the append.

Can anyone suggest a good program for merging/combining AAC-LC .MP4 files so that I can mux it in MKVmerge without this audio issue the Append is always giving me?
