I've watched alot of videos about multiple audio tracks but none of them seem to help. I'm doing everything right (i think) and follow every single step in the videos but they simply do nothing.
I'm using track 1 (desktop audio) and track 2 (Mic capture),
in the settings, output tab i've selected the advanced output mode,
and i have selected the two audio tracks that I'm using, but it'll only record the desktop audio. However if i switch those two places so my mic would be on track 1 and desktop audio on the second and start recording again, I could hear only my mic audio and not the desktop audio.
In the mixer it shows that both are working and the bars go up if use the mic or have some desktop audio.
I don't want to use VLC because it doesn't work with sony vegas pro 16.
How do i fix this problem?
 
Most video players will only play back one audio track at a time.

People will suggest using VLC to play back your recorded file because it will let you verify whether both audio tracks recorded-- you can choose which available audio track to use during playback from the Audio menu.

If that menu only shows a single audio track, or plays back an empty track, then you know something went wrong while recording.

If VLC plays back the audio tracks the way you expect, but your editing software does not see it, then the problem is with the editor.

It is my understanding that many users have difficulty getting certain files to work properly with Vegas.

I don't use Vegas myself but I might be able to comment further if I could see a logfile.
 
I tried using VLC and the both track were in there so I know it works, but you can not edit VLC files with Vegas there is nothing wrong with it but it does not support VLC files (to my knowlage). I need both tracks to work ok mp4 (which Vegas does support)
 
VLC is a media player, not a video file format, so there is no "VLC file". You just configured OBS to produce a file type your video editor doesn't understand. If you need the video file to be mp4, go to Settings->Advanced->Recording and activate "automatically remux to mp4 (record as mkv)". With this, OBS will record to *.mkv and if you end the recording, it will convert it to *.mp4 which you can use in your video editor.
 
Except that a lot of the times, it is the problem. People expect all audio tracks to play simultaneously.
Media players NEVER do this.

OBS 23.1 is borked. The media player is NOT the problem when people record MULTIPLE tracks for POST processing before final rendering.

This for example is a recording I literally JUST recorded that has multiple audio tracks in it.

Are they discreet audio tracks that can be selected individually and only have their singe respective source in them? Because I've been farting around with this for several days now after the upgrade to 23.1 and no matter how many input tracks I select, they all end up being muxed into every track. That is to say I have 3 different input tracks set. Yeah, all three tracks are there but they're all identical. Each one is a duplicate with ALL the sources in it.

Can you please show me your multi-track settings?

HERE is the link to the post I made yesterday: https://obsproject.com/forum/thread...record-multiple-discreet-audio-tracks.107435/
 
I cannot comment in the Linux thread, since I don't know if the interface of the Linux version of OBS behaves differently to the Windows version, but in the Windows version you direct audio to several audio tracks this way:

In this setup, every source is mixed into track 1. Additionally, you write Desktop Audio to track 2. Guild Wars Audio to track 3, Headset to track 4 and Mikrofon to track 5. To make this with that many tracks, you have to check tracks 1-5 in Settings->Output->Recording.

This way you have a quick overview of all sources in track 1 and have all sources separately in addition for postprocessing. You don't need to write everything to track 1 this way if you intend to postprocessing anyway, but it's convenient for quickly checking the recording without having the need to switch audio tracks in the media player.

In the picture in your other thread, no audio sources were checked for track 2, so a completely silent track 2 is written by this setup. And no tracks were checked for Mic/Aux, so Mic/Aux isn't written to any track by this setup.

That setup window is identical to what it looks like in Linux. What is happening is no matter how many tracks I set, everything gets instantly mirrored across all of them. In the example you show I would end up with 4 tracks but each one would be identical with all 4 sources combined on each one. And a selection for "mic" no longer appears anywhere in any source selection drop-down. Even the ones specifically for microphones.
 
In this case it seems the player software you're using doesn't actually switch or distinct between tracks but always only accesses the same track - the track you consider being mirrored.
I just created a test recording with my above setup, and I was perfectly able to hear in track 1 all sources mixed, in track 2 the desktop audio (my music player and Windows sounds) only, in track 3 game audio only, in track 4 headset only, in track 5 the microphone only.

OBS 23.2.1 is behaving perfectly well in this regard.
 
I have this issue too. I've set things up as suggested:

1. Use a format that supports multiple audio tracks,
2. Check the tracks I want to record, in Settings,
3. Select which sources go to which tracks - i Advanced Audio Properties.

No matter which sources I assign to which tracks, the result is:

1. The source assigned to track 1 gets recorded,
2. The source assigned to track 2 does NOT!

Any ideas would be welcome.

Many thanks
 
Ok, just to follow up om previous post. I find that, as usual, OBS is not at fault.

The Recording DOES in fact contain both the tracks I specified in OBS.

What I didn't fully believe/understand is that they are hard to use in various media players/DAWs etc.

I tried VLC, my goto, and it would only find track 1, I then tried "exploding" all audio tracks in my DAW (Reaper) but again it only found track 1.

In desparation I delved into ALL the various settings in VLC and finally found one that allowed me to select Track 1 or 2 to play.

It work, it did record after all. Relief!!!

What I need now is an app/DAW/whatever, that I can use to EDIT my recording as my WIFE has a deadline of this morning to record an item (video & her talking and me on keyboard for inclusion in a fellow churches Sunday service stream AND I need time to mix it AND she only wants to do one take as it's impromtu .

I would like to use Reaper if possible as this is my goto DAW and supports video and audio well. I just need a way to access both audio tracks SIMULTANEOUSLY.

HELP!
 
I know this post is old, but I figure I can at least leave an alternate solution any how for those who come here.

I use an editing software that has yet to properly accept a video file with multiple audio tracks correctly, and so a workaround is needed for me to work on my projects.

What I've done so far is input the video into a audio editing program called Audacity using the FFmpeg library add-on. This submits all of the tracks into Audacity, after which i can export each track individually to place into the editing software afterwards.

Since they are being directly ripped from the video, placing the audio back under the video in the software doesn't require any kind of re-syncing, while still keeping the tracks separate and open for whatever kind of audio balancing/editing you could ever need.

This option is free as well, so no harm in trying it yourself.
