Hi , I was trying to guess the channel order or Tremor decoder for 5.1 channel file. Though the standard state it to be FL,C,FR,RL,RR,LFE but in my opinion its FL,C,FR, LFE RL,RR. I am not sure if my guess is correct . I came to this conclusion after downmixing from five to two channels. If i assume the channel order to be as per the standard then my two channel output is not correct but if i take it to be FL,C,FR, LFE RL,RR. then i can hear the output perfectly fine. I used matlab also but could not figure out which one is LFE as i was expcting the FFT plot to be less then 400 hz atleast. I tried listening but all the channels seems to have same content. I would appreciate if somebody can tell me how to decide which one is LFE out of all 6 channels. thanks, -------------- next part -------------- An HTML attachment was scrubbed...
