Significantly worst audio quality with the EXCEPT option enabled

Significantly worst audio quality with the EXCEPT option enabled.

Using 2.2.2 beta. Not tried with other versions

Here is a comparison, using Teardown, the video game. comparison.zip I have seen this happen in a couple of games I've tried, but for some reason some programs, e.g. iTunes, do not exibit this behaviour.

indeed bro，i tried recording in CSGO and do a comparison,its obviously downgrade the audio quality,so i wouldnt really use this version until the problem fixed

I'm having the same issue, but I wouldn't call it "worse", just missing levels. It sounds to me like sometimes it's just chopping all the high frequency noises off, and sometimes it sounds like the audio has been "doubled" and just sounds kind of buzzy.

My current solution is just to every single executable I can think of that would be on the "EXCEPT" track to a capture and use that. Really annoying though, please fix.

Have the same issue. When I use the "Capture all audio EXCEPT sessions...." the sound captured becomes tinny for lack of the better word. Its like it has lower bitrate? maybe? Hard to explain. Essentially some Audio Quality drops when using the EXCEPT option. Would definately appreciate a fix cause putting all games and stuff manually into that is a bit annoying

[zolgs]

yup im having the same issue right now

[MevliN]

same issue here aswell

This is happening due to the API's behaviour of capturing audio render streams from the child processes of the process that is specified in addition to the audio of the parent. For example, the plugin will try to capture the audio stream of both the steam.exe process and whatever game is running as a child of it when matching something else in exclude mode, but the audio captured from steam.exe will already include that of the game leading it to be duplicated.

There is no good fix here - say if you exclude capture one steam game then the only reasonable course of action is to not capture steam itself but do capture the child games, but the audio from steam will go missing.

Some level of de-duplication should be possible with parent/child elimination, although querying parent PIDs will probably need tlhelp32 or WMI.

Same bad audio for me that sounds muffled but it only does it occasionally

people may not necessaryly need audio from steam itself，i guess at most situations
