The settings od audio card is the same.
I attach the original audio file and the other one editated video by Edius 9. On the video there is a slightly too strong audio in the background but I didn't want to change the original settings.

I'm not an experienced guy but it seems there is a "Poor frequency response" on the edited voice.

With both files, the voice over is crystal clear on my system.
The big difference is the actual mix between the voice over and the NAT sound.

I would redo the mix and lower the volume of the NAT sound so that the voice over is more pronounced. When the voice over is not there, bring up the NAT mix. When the voice over returns, once again lower the NAT sound so it is in the background.

Hello,

I enclosed a WAV file - using your MP4 video - saved as WAV - and I only retain the dialogue (no background noise). If you play back the Provia audio.WAV and compare that to my "From MP4 (only voice)" - you can hear the difference.

Even more significant - you can see the spectrum from the same location in both files - the Provia audio has more bass whereas MP4 version is suppressed.

Also the AAC codec strips away the 12Khz and higher frequencies - you can see that very clearly - it is a function of the bit rate you choose.

Sometimes when using a motherboard sound card I get noise caused by interference somewhere in the system. Also a dedicated sound card can have ASIO drivers which may help in other programs (not EDIUS).
As I generally use a Blackmagic device with my system it does not really matter because in EDIUS the sound will come out through the BM card and ignore the sound card.

Sure, you are right. I'm not a fool who doesn't understand this. I had to take a filter out on the audio on the Edius 9 timenile and without that filter the violume of the voice went down.
Anyway I thank you.

Nice test, I understand. Thank you.

As I have mentioned before, if you want really great audio, don't use EDIUS audio filters. Manipulate your audio outside EDIUS - save as one WAV file at 24 bits, 48khz, stereo - and load that into EDIUS.

Remember, EDIUS is meant to be a VIDEO editor - not an audio tool.

Out of curiosity: do you think a DAC like it could be useful to me or it is so cheap and it is better to use the integrated audio card in Asus PRIME X299-DELUXE?

thank you!

I never liked the sound from the motherboard chip. The TIPS connector on most motherboards and builtin sound system gives problems like cross talk between the 2 audio channels.

I have one Focusrite Scarlett 2i2 too - cheap and very good sound too. Totally USB powered - no need for external power.

I have always had good experiences with Motu products for my desktop workstation, where multichannel audio was used with ASIO drivers.
As Jerry mentioned the are a bit higher priced.

For my current mobile system I use my Matrox breakout box to keep things simple...
