It is OK, these files are standard decode without apply Atmos metadata.

But automatically the 3 files are joined in a Dragon4.wav (Duration: 01:02:30.02) but now at only 16 bits and simple header without channelmask.
The output file must be a .w64 or .rf64 to avoid the size limit of .wav files and preserve the 24 bits precision.
Not a simple join, the Atmos metadata are used to create the desired output channels. I want 5.1.2 and create 8 channels using rf64 header with big files (Star Wars I: 5.84 GB) but without channelmask and only 16 bits.

BTW recode Atmos to eac3 5.1.2 can be for players without Atmos support or to reduce size, maybe until 448 Kb/s, and the 16 bits can be aceptable.

The channelmask is not important for eac3 encoders because seems is ignored. For me, with the render target 5.1.2 front, I can recode to (L R C LFE Ls Rs Vhl Vhr) without remap.

For me the first feature request by the moment is decode TrueHD.

The ADM format is useless for me.
