Qaac Aac lc sbr He 192 Normalize

I found it a bit fishy but I still tried with this command: stdout.wav -normalize | qaac -v 192 --he --ignorelength -o %_.m4a - but the strange thing is that by clicking on the menu at the end it does not mark a .m4a type file but rather an .aac type file as I wasn't sure I tried 2 ways but without success 2: stdout.wav -normalize | qaac -v 192 --ignorelength -o %_2fre.aac -

Because eac3to need Nero 7 installed to decode AAC, NeroAacDec is not enough. Decode it before to wav with ffmpeg (A/V Recode) and after normalize and recode to AAC.

What menu?
Without success?

Both commands works fine for me (of course over a source than can be decoded by eac3to), the first create a file_.m4a (aac HE in mp4 container) and the second a file_2fre.aac LC

is there a universal way to enhance the dialogue (center channel) without applying additional filters (like dynaudnorm)?

Read the thread convert 5.1 to stereo

Players can be instructed to enhance the FC in the downmix, for instance with mpc-hc:

i'd love to keep it at 5.1 and make it playable across various devices with good sounding dialogue while maintaining the dynamic range as much possible and not using any hardware methods like DRC or Night Mode. after looking at multiple methods, i can't find a better solution than "volume=x.xdB (if needed), dynaudnorm=p=0.9:m=2:g=31:f=300". there's no easily detectable volume pumping even in complicated scenes BUT the drawback of this method is the loud parts (like music, etc) become even louder so it's difficult to preserve the balance. wondering about any additional tweaks to try.

Do you have to -keepdialnorm when extracting atmos? I remember using the old eac3to and it would automatically remove dialnorm as it was supposed to help in some way. I'm using -keepdialnorm from now on as I think it's the best thing to do especially as dgdemux and makemkv keeps dialnorm too.

Extracted with -keepDialnorm my Denon player show DD Atmos and decoded with Dolby Reference Player seems fine.

Without -keepDialnorm (or converted to mkv from m2ts with MkvToolnix) my Denon player show DD+ and decoded with Dolby Reference Player we obtain only silence.

Like I say MediaInfo show JOC for both and Cavernize decode both with the same output (seems more permissive).
