Converter for audio files only
PopCorn MKV AudioConverter converts audio tracks in .MKV files from formats that can’t be played back to formats that can, f.ex. DTS-to-AC3 for the NMTs that don’t have DTS downmix built in, or AAC 5.1 to AC3 5.1 for full surround plackback.
Also converts OGG Stereo to AC3 Stereo for the NMTs without OGG playback, and FLAC 5.1 to AC3 5.1 for full surround playback.
