got a DTS 5.1 track here, eac3to reports it as DTS 5.1, while PowerDVD says it's DTS-ES 5.1
so which is right in this case? http://www.sendspace.com/file/79229m |

I just got the Wall E Blu-ray and it's supposed to have DTS-HD Master Audio 6.1 but eac3to shows only 5.1.
I was wondering what the "($f)" is under Active speakers. Edit: let me clarify, the box says 5.1 DTS MA but blu-ray.com says 6.1 DTS-MA and several reviews have indicated 6.1 so maybe I'm just reaching for something that just isn't there... Code:

If you just need the wave files, then you can just do as already suggested and convert directly to waves.

madshi, could you please implement a kind of detection which reports 2.0 tracks being mono or stereo tracks? would be useful for older movies, sometimes those original tracks are either 1.0 or 2.0 mono. then it would be possible to distinguish if a studio included an original 2.0 mono track or if they did use a modified stero track.

When you give the adrress of video and audio; this is the result:

In case of a 7.1 track, SL/SR are the channels intended for the side speakers while BL/BR are intended for the back speakers. In case of a 5.1 track, the surround channel pair can be played through SL/SR with the back channels not playing any sound. Or you can use some funny algorithms to upconvert 5.1 to 7.1. If you play a 7.1 track on a 5.1 speaker setup (or if the studio downmixes 7.1 to 5.1) the 5.1 surround channel pair usually contains a mix of the 7.1 SR/SR and BL/BR channel pairs. It doesn't matter much whether you name the 5.1 surround channel pair SL/SR or BL/BR. But IMO SL/SR is the correct name. Quote:

The "($f)" is the hex value of the "activeSpeakers" bitstream element. What it means is shown in the log, namely "C L R Ls Rs LFE". These are the speakers contained in the DTS-HD track. You can see, there is no Back channel in the track, just plain 5.1. Quote:

Why does ArcSoft lower the volume? Don't ask me. It's caused by the speaker mapping the studio has chosen. DTS-HD supports a big number of different speaker mappings for 7.1 streams. There are at least 3 different mappings the ArcSoft decoder decodes perfectly. But this specific speaker mapping used for this track seems to confuse the ArcSoft decoder, which makes it decode the track with lower volume. It's not a terribly bad thing, it's more or less similar to the effect DialNorm has. If you want, you can report this problem to the ArcSoft guys (together with a small sample). Should be easy for them to fix. Just ask them to decode the sample as 5.1 and then as 7.1. The 7.1 decoding volume will be lower, which doesn't really make any sense. With almost every other 7.1 track on the planet the 7.1 decoding volume is not lower. You can use "-logdts" to see which speaker mappings a specific 7.1 DTS-HD track uses... |
