MMH Version 6.3 - New Dolby Atmos Helper tool & updated Multchannel Remix tool

I don't understand then why the m4a files

The MKV to m4a with MMH Extract Audio from MKV is lossless 24bit TrueHD Atmos

You are encoding to lossy Dolby Digital Plus 16bit with DDE.

Why do you think lossy should be same size as lossless?

The question is whether this m4a atmos lossless, achieved in this way, preserves the metadata of the spatiality of the original BD.

 

[HomerJAU]

Yes. MMH just takes the original TrueHD stream and copies it to an mpeg container. This is a copy of the stream on the disc and is identical to the stream played by a BD player. There is no decode/encode.

The thing is that this m4a 24/48 atmos lossless is not playable by portable dacs (daps, like Shanling M6 ultra). So, I need a m4a atmos lossy 16/48 (5.1 or 7.1) that is readable by daps, but keeps the original spatial metadata, how can I get it?
