Aron....Thanks...Roku is set to direct play when using the Plex App and the files on plex are .flac When playing the .flac files via Roku and direct play, it shows as .flac 5.1 My DTS 5.1 files play OK, same with 5.1 AAC, AC3 and PCM. Something about .flac and 5.1 music and plex/roku I guess? These are all 5.1 music files so a bit off topic to BEQ but I will be doing some more homework on 5.1 music files especially after my experience below.
To satisfy my curiosity about .flac in an .mkv video container using BEQ remux, I did the following:
Re-muxed Black Panther again using beqdesigner, this time in .flac Also, noticed an option for EAC3 within beqdesigner so re-muxed using that codec also using the default 1,500 kbps option.
The flac files play and sound much better than the 5.1 flac music files....this is why I need to do more homework on my 5.1 flac music problem, but no biggie since I can enjoy those using other formats for now.
For the BEQ remuxes, there are some differences I noticed when playing the different remux formats.
The flac mkv is about 9 dB quieter than the EAC3 mkv file. Just a quick measurement using my trusty ole' radio shack meter to dial in 75dB during the same movie passage, I had to turn up the MV on the AVR 9dB higher for the flac file to get the same SPL. This was consistent on several different movie passages.
I also noticed a difference in fidelity, for lack of a better term, between EAC3 and flac....not sure which one I like better at this point. Using the same level-set SPL using the meter for my listening experiments, I listened to the first 4 min of the Black Panther with the same BEQ filters on both remuxes.
There's some really low stuff happening in the beginning of the movie when the back story of Wakanda is being described with the animations. Sounds pretty awesome with BEQ in both flac and EAC3 remuxes. Then right after that animated backstory, the movie picks up in the present day on a basketball court with rap music playing in the background.
With the EAC3 remux, the bass in that rap music about threw me out of the chair. I did this several times going back and forth between the EAC3 mkv and the flac mkv and the result was always the same thinking I must have had the volume different when I first did the comparison. I'm guessing that bass is round 30Hz and with flac, the bass is more in line with what I was getting with the PCM mix. The EAC3 mix was crazy with this music....weird.
So now I'm torn....I like the fact that EAC3 is 9dB higher than flac so I don't have to raise the MV so much on the AVR to still get the BEQ awesomeness. This is especially desirable since family members have already forgotten to turn the volume down after a BEQ movie...lol. But, I'm not sure what to think about that music scene being so violent with EAC3. Maybe that's how the original mix was....I'll have to go back and listen to the scene again on blu-ray.
Oh yeah....almost forgot about the files sizes....flac only increased the file size by about 5% over the original .mkv and EAC3 increased the file size by about 2% using the default 1,500 kbps option. Much better than the 50% increase with PCM.
Now, my end goal is to not only have some remuxed demo scenes on the plex server for hassle free presentation but now I have another goal....remux our favorite blu-rays and burn them back onto BD-R for the family to enjoy hassle free BEQ movies when I'm away.
Just need to decide what format to use now....flac or EAC3.
Hope some of this helps and sorry for getting a bit off topic.
