Convert 6 Channel Audio only AAC, WAV, DTS to AC3, MP3, WMA and Convert 6 Channel Audio in Video AVI, MKV, MP4 to AC3, MP3 Stereo or 6 Channel


Convert AAC to AC3 5.1

“I have an MKV with 5.1 AAC soundtrack. I want to play it through PCH in its full 5.1 glory. I understand that PCH can only play it in PCM stereo. That’s why, I have extracted the AAC soundtrack and now I want to convert it to AC3 file and mux it back into MKV.

To my shock, I have discovered that there are NO tools available (either free or paid) that can easily convert 5.1 AAC to 5.1 AC3. Some people have listed on internet, long and time consuming methods that convert 5.1 AAC to 6-channel WAV file, which then needs to be converted to AC3 with manual mapping of channels. Apparently there is channel assignment mismatch while conversion from multichannel AAC to AC3.”
