With some experience, you can pinpoint the channel sequence graphically. Audacity, with the FFMPEG plugin enabled, can usually open typical video/audio interleaved media types and display a track overview.

However, typical 5.1/6.1 and 7.1 mixes can be identified by their typical patterns when you open them in an audio editor.

In general, it is not easy to verify a channel mapping by listening to a sound track. There will also be hints given if this occurs. You may try leaving them at full level and check with the audio level graph wether clipping occurs. I reduced the level of the surround channels by -6dB to avoid clipping, because two channels are mixed into one.This is a safety measure and may actually not be necessary, as typically, surround signals are not going full scale. I'm almost sure that the layout showed in the table is not true, since that would mean the front speakers would be messed up too, which is almost definitely not the case (i think I would be abe to tell).ĭoes anyone have any experience with this ? Any help would be most appreciated.īildschirmfoto um 23.01.41.png (18.45 KiB) Viewed 6035 times mkv file with MediaInfo, which gave this result: What is the channel order in DTS-HD 6.1 ? Is there a way to find out ? The only thing that I tried is analyze the. however when I play the DCP in our cinema, I can hear that something is definitely wrong with the surround speakers (like the sound is not always where I think it should be), but I'm unable to tell exactly just by listening. The default 5.1 channel mapping matrix in DCP-o-matic after opening the. mkv, but I cannot figure out how to map the audio channels - the source is a DTS-HD in 6.1 format, which I'm trying to map to 'classic' SMPTE cinema 5.1 / 7.1 (therefore either leave out the Cb channel altogether or put it in both BsL / BsR), however I'm unable to find the channel layout for this particular format
