windows upsample is worth it ?

[sohail14]

is there any difference ? can i set max ? it is good ?

If it's in the Sound properties, it doesn't upsample anything. It's just the maximum quality format that can be fed into the audio output hardware.

It is actually bad. Generally, you want to avoid sample rate changes if possible or use a high quality resampler instead.

windows default is best right ? this is my default

You want to match the sample rate of the content you are listening to, which is probably going to be either 44.1khz or 48khz.

 

Anyway, aren't you using dolby atmos for headphone? That locks you into a certain setting.

It gets resampled if you're using it in shared mode, which almost everyone is. Different programs may use their own resampler, but if there are multiple programs sharing one device they all have to use the same sample rate.

Luckily it's not quite that bad in most cases, only DirectSound (which is one of the many SRC options in Windows) uses that terrible interpolation. In most cases the individual programs detect the device's sample rates and do their own resampling (required by WASAPI). I believe the most commonly used method is Audio Resampler DSP (Resampler MFT), which does a lot better than Directsound.

 

I can't find any src-compare style digital measurements for it, but here's an RMAA loopback (limited by system resolution). Not a proper measurement per se, but you can also see that it's a proper FIR filter here.

The really bad resampling is for applications that use the directsound or mme interface. I think this is still the default interface of many applications like vlc, foobar2000, and the spotify app. Games that use xaudio2 will get the better resampler. Web browsers I think use wasapi and thus probably use the better resampler.

 

I am not sure about the overall popularity of the newer interfaces, but in any case, it still is best practice to avoid resampling or use a high quality resampler like sox if possible.

Use the same quality that you're listening to. upscaling or downscaling can cause aliasing.

game, tidal (master) , vlc movies can windows default is best ? different content can change sample rate automatically in windows ? i will use only if dolby games otherwise no cuz its compressed audio quality

[an actual squirrel]

with tidal, you can enable the "exclusive mode" option to avoid resampling. 

 

I suggest you use dolby atmos for headphone for games. It doesn't require atmos, it can also work with 5.1 and 7.1 surround sound. The audio will be less compressed with dolby atmos for headphones since you are working with more channels. Also, more channels means more directional information ,which is important for games.

where can i enable that exclusive mode in windows ? . im playing games like story games but but its compressed audio quality , between 16 bit and 24 bit . more channel great but this software  increasing sound and bass that means increasing some sound this actually decreasing from  actual headphone quality right ? sorround sound without any increase some sound or decrease its great . srry for my english hope u understand

exclusive mode setting in the tidal app. The dynamics are going to be improved more from having more channels than from selecting 24 bit.

so its not decrease sound quality using dolby atmos for headphone application right ? and i can use all games for better audio ? even non dolby supported games ? like hellblade and re 2

hellblade is a unique case because it has binaural assets, so in that case no. But re 2 yes. Re 2 even has atmos support, doesn't it?

for re 2 i received email from atmos and can i use dolby with binaural audio on in re 2 game settings ?

 

[an actual squirrel]

Turn the binaural audio option off when you use dolby atmos for headphone. And turn atmos on in the game.

actually re 2 have atmos support but not atmos for headphone , i see supported list  in windows store they not mention re 2 

[an actual squirrel]

That's how it is supposed to work. Atmos from the game goes into dolby atmos for headphones.

 

The name even tells you that it is meant to take dolby atmos and make it for headphones.

whats your opinion that which is best binaural audion in game like re 2 , hellblade  or dolby atmos for headphone 

[an actual squirrel]

With Hellblade, since it uses binaural recordings, those assets will always have the same position on every playthrough. They can not change dynamically. Do you understand? So this is not particularly good for gaming.

 

Whether you use the virtual surround sound option in re 2 called real time binaural or choose dolby atmos for headphone instead, either is better than playing in stereo. Direction of audio is poor in stereo.
