Dolby Digital 5.1 AC3 Channels
Can someone please tell me what each of the six channels are in Dolby 5.1?
I have video from a Sony Handycam DCR-SR100 that records Dolby Digital 5.1 audio in AC-3 format with MPEG-2 video. I can tell for sure that CH6 is the subwoofer channel, but the others are unclear. This is what I think they are from the audio: CH1: L (Left) CH2: R (Right) CH3: LS (Left Surround) CH4: RS (Right Surround) CH5: C (Center) CH6: LFE (Low Frequency Effects) All literature I've found indicates L, C, R, LS, RS, LFE, but the audio files with some video I recorded indicate as above. I couldn't find a definitive answer by googling.

ello-so it looks like your using win- try 1st goto win sound/playback+recording devices (sound properties) and check playback speakers configuration there- it will play a test tone for each speaker-either for 5.1 or 7.1>> that's the way files will playback anyway... something like, l/r c/s rl rr sl sr.. or it does on 1 win10 system.. 5.1 just leaves out sl+sr. yeah? reaper also renders what channels you set in an order of 6,or 8channels.. |

Thanks, Bri1.
However, I don't have a 5.1 system connected to my computer. I'm trying to identify the channel order of the 6 channels of an existing AC3 audio file embedded in an MPG file that was recorded using my camcorder. I'm assuming that the channel configuration is standardized, but I cannot seem to find the information on the web.

There are actually a few different "standards".
The most common is SMPTE, which is: 1 - L 2 - R 3 - C 4 - LFE 5 - Ls 6 - Rs Film is another: 1 - L 2 - C 3 - R 4 - Ls 5 - Rs 6 - LFE The last that I'm blanking on the name of is: 1 - L 2 - R 3 - Ls 4 -Rs 5 - C 6 - LFE

There is no doubt that channel 6 = LFE in the files that I have.
