Can someone explain this type of Audio encoding?
June 3rd, 2014
I got an MKV which has an unfamiliar audio encoding. I asked the encoder but did not get an answer.
My hardware Media Player cant play it (plays it as audio clicks)
Can someone explain to me what does 6 channels set to L/R mean?
Format profile : HE-AACv2 / HE-AAC / LC
Channel(s) : 2 channels / 2 channels / 2 channels
Channel positions : Front: L R / Front: L R / Front: L R
Sampling rate : 48.0 KHz / 48.0 KHz / 24.0 KHz
Following encoding is more common:
Format profile : HE-AACv2 / HE-AAC / LC
Channel(s) : 2 channels / 1 channel / 1 channel
Channel positions : Front: L R / Front: C / Front: C
Sampling rate : 48.0 KHz / 48.0 KHz / 24.0 KHz
Or…
Format profile : HE-AAC / LC
Channel(s) : 2 channels
Channel positions : Front: L R
Sampling rate : 48.0 KHz / 24.0 KHz
Thank you

See that link so you can just see that you are f*cked-up lol. Many people with the same problem. In pc it is solved but becouse you play in a hardware player probably the best option is download another version of the movie…
That is not a nice language.
In any case, that post was made by me so it is no use referring me to my own post and your reply does not answer the question raised here.
I think it means it has triple audio (in different languages) but it’d help if you’ll provide the file name.
Thank you Roberto
It was actually a dual audio anime but that details are for a single track of the audio

Thank you edwoodweb
There isnt any firmware upgrade since the model has been replaced ….however…that is not the point
I have already downloaded alternative version. I could have also extracted the audio and convert it and remuxed it back in. Again, that was not the point.
All I wanted to know for my own information, was…..what does it mean?
Is it an error in encoding OR does it make sense to have 3 sets of L/R?
It’s AAC Advanced Audio Coding v2 High Efficiency with PS Parametric Stereo and all this means it’s the highest possible compression where only one audio track is encoded and the differences between Left and Right are encoded to reproduce the 2nd audio channel.
There are 3 different forms of AAC audio, AAC-LC, HE-AAC v1 or AAC+ which adds Spectral Band Replication to AAC-LC and HE-AAC v2 or eAAC+/AAC++ which adds Parametric Stereo to AAC+.
AAC-LC is supported by most recent hardware media players, whereas AAC+ is less well supported and eAAC+ is largely unsupported ATM.

It is probably just MediaInfo not reporting things correctly. It used to do that with my eAAC+ audio encodes. It used to say it was single channel when it was stereo.
If you want it to play then make sure the audio is AAC-LC.
will the file play on a PC ?
can you determine how the audio is distributed by the players codec on the PC ?
Thank you Mighty_Marvel for the information. It was very informative
@edwoodweb
yes…kinda
MPC-HC with mega codec pack 7.60 would not play it at all with default setting. After changing the AAC codec AAC => change libavcodec to libfaad2 it would play it.
MPC-HC with mega codec pack 7.70 seems to be able to play it with its default settings.
However…..I dont know what actually happens with the above changes
Does it play completely OR just ignores the additional L/R tracks?
If anyone what to test the actual file, here it is:

Does it play completely OR just ignores the additional L/R tracks?
playing it with Zoom player & ffdshow audio codec the input is just 2 channels and it ID’s the input as “Stereo 32 kbps SBR PC AAC”
