Even when comparing Audition 2019 to Audacity (Best Quality) on that SRC comparison site, there are no audible differences between them (differences only above 20500 Hz), Audacity is just as good.

Wrong thread, @PCU... this is about LAV Filters. Please stay on topic here, and create a new thread for all the unrelated audio questions.

Does Windows 10 offer native AV1 D3D11VA hardware decoding apart from Media Foundation?

Microsoft of course doesn't provide anything out of the box anymore except Media Foundation. But any software, such as LAV, can of course make use of D3D11VA to decode AV1. Once I get access to any hardware, of course.

Why don't I see such a playback glitch when playing DVD content? Both audio and subtitles are switched without stopping the video stream.

That topic is done. I will not waste countless hours redesigning something that spans potentially multiple components and may not even work fully since third-party components are involved (renders), which I do not perceive as a problem.

Downloaded the sample just for fun. Of course no source filter would play it, but I was a bit surprised to see MediaInfo reporting 10 audio channels.

Does this madness ever stop? Will the next generation videos have 20 audio channels so users need a home theater setup with this number of speakers?

I think that 8 channels are already overkill, more than 6 audio channels are just a bloody hype...

Just my 2 cents...

And then count in the different interference preferences of furniture and closet contents ... better you have a separate home cinema room in your basement.

I had already noticed LAV couldn't handle 10-channel audio when I tried testing some stuff with the Audio Creation mode of my X-Fi that allows up to 10 channels of "Multi-Channel Wave", but I figured it was a really niche case and no consumer file would ever use that. The additional two compared to 7.1 were 'Rear Center' and 'Top'. Is that standard in Windows' multi-channel wave layout?
I assume this sample here from Doom doesn't use that and it's rather two or more height channels like in Atmos?

I have an Intel i9 10900K cpu and an Nvidia 1080 gpu. I am currently the latest MPC-HC version (1.9.8 from clsid2) with LAV video version 0.74.1.75.

Would it be better to use D3D11 or just going directly for software decoding (none)?

Thanks!

I like D3D11 for 4K HEVC but for everything else software is better, even 4K HEVC is fine in software on a 10900K but it does heat up.

D3D11 is only beneficial if you use madVR or MPCVR. Because those renderers supports D3D11 native mode. With EVR-CP as renderer the best choice is DXVA2 Native (or None for <4K stuff).

I typically use hwdec on my old machine (intel hd4400 igpu).

However, with 4K30 8bit Hevc, software decoding seems to work better (avoids gpu @100% +frame stuttering).

Intel hd4400 only has partial acceleration for HEVC, which isn't very good. So with such GPUs you often get better results with CPU decoding.

Hi guys. I remember discussing this many years back on this thread, but I'm wondering has anyone come across a way to achieve this with lav audio or some other external filter.

I'm trying to filter out frequencies above a certain frequency from the LFE channel, because many blu-rays I have such as the Dark Knight, have some awfully strange, high frequency content in the LFE channel. AVRs must normally filter this but as I don't have an AVR, I can't get rid of them so the sound flutters/clips (it sounds like that) in some scenes. I actually only have a 2.1 channel system (Outputting as 2.0 to LS50W + it then outputting low frequencies from the 2.0 to a PB16 Ultra sub). I have until now been using LAV Mixing to mix to 2.0 with 0.71 as the mixing level for center/surround, and 1.58 for the LFE Mix level.

I'm now trying again to see is there a way to solve this as other family members noticed the problem last night when I was "showing off" my system. Do you know if LAV Audio would ever have the ability to filter these frequencies out before mixing, as its difficult to filter them after the mix is done. I'm thinking one way would be to send the audio without mixing, to ffdshow raw audio or some other filter, and let it do the filtering (via a convolver maybe) and then mixing to 2.0 after the filtering.

Any inputs welcome. It'd be great if LAV Audio could do it but not sure is there any plans?

Can anyone confirm new H.265 4K SAT channel Mooz 4K (here's my record 20201031-170739_Mooz 4K.ts (56 MB) https://yadi.sk/d/NngfIFAIVyK-hQ ) with LAV Video Decoder 0.74.1-75 (I didn't test earlier versions) as minimum on nVIDIA's videocards GM206 and newer can't be accelerated with DXVA2 (native and copy-back) or gives artifacts in Win7x64? With CUVID hardware acceleration works well. MPC-BE, Cyberlink and MainConcept accelerates via DXVA2 well too.
