DirectShow Audio Source Plugin

If u have a double audio card such as turtle beach headphone, you must download VB-cable, set playback sound of your program such as TS to direct sound and VB Cable input, then set up in recording device to listen your virtual audio cable to your communication device.
Now to obs add a global source with cable output(VB-audio virtual cable) and done. all works fine.

I hope you can understand, my english is really bad.

I'm trying to use this to play music from WinAmp in specific scenes along with VB-Cable. However, for some reason the audio cracks sometimes (it's not the files - it doesn't happen when I'm listening to it through my Realtek device) which annoys me like crazy. I don't know if it's related to the DShow Audio plugin or VB-Cable or the WinAmp DirectSound Output plugin (I'm running v2.6) or WaveOut plugin (it happens with both). but I was hoping if anyone would have an idea on how to solve my problem... It's not the stuttering that others had a few pages back, in my case it's like you're listening to an old, mildly scratched record. It doesn't matter whether I use 32-bit or 64-bit.

Edit: It also happens when I try foobar and VAC. It also happens when I have it set to 'output to stream only'... ._. I'll reinstall the plugin and see if that helps...

For anyone else experiencing the audio stuttering issue, in my (exhaustive) testing and troubleshooting, I've discovered something that seems to solve the issue, at least for me.

This is wild speculation because I haven't actually looked directly at the source code and I'm not familiar with the DirectShow API(s), but I think what is happening is that the scene attempts to capture the DirectShow devices too soon after initializing them for use, and as a result is unable to capture the audio source properly. This would be strange since I assume that OBS itself uses the same APIs to access those devices, but there might be some sort of conflict/race condition between the plugin and OBS accessing DirectShow sources at the same time. As I said this is completely wild speculation, I would love to hear from the developer to see if this sounds like a possible cause.

What worked for me was increasing the "scene buffering time" under Advanced in the settings of OBS (v0.637b as of writing). I had previously modified this to be 400ms, but I think that might be too short. I've increased it to 1200ms and have since had zero issues recording microphones properly. Your mileage may vary (I imagine it depends heavily on both your CPU and the devices themselves), so try playing around with various delays and see if it works for you.

This worked the first time I used it, bumping it up to 1200. Then a few relaunches of the stream later, it was back to messing up still at 1200. Just to test, not to keep it permanent, I pushed it to 1500 and it started working again.

Again, a few restarts of my stream later, it was right back to it.

And idea as to why? This issue makes my stream completely unusable!

Thanks!

Hey mate, any chance we could get a separate Gain control for the DShow plugin channels? x) Sadly I am having to do some jiggery-pokery to get things working since, for some reason, OBS muffles sound recorded via my Wave-out while your plugin records the same sound clearly. This makes me want to mute the internal sound, and use your plugin for the game sound. The drawback of this is that the volume is, of course, tied to my windows volume. To get the proper sound out I need to keep it at 100% which makes me deaf :P. So therefore a separate gain control would be handy to counteract this!

HUGE thank you to Altair for this. I've been trying to get audio from my DAW (SONAR) to OBS for a few days with nothing but trouble. Turns out this minor change in value was the little fix I needed to pull it all together.

THANK YOU.

Hi there,

as I don't know what exactly the problem is, I will post here and on the thread of the Microphone DSP Plugin (even though I think that the latter on is the problem - not your plugin. But just being sure and stuff...)

I'm using your source in an "AFK Scene", where I plan to play music coming in from a different input (AUX In on my Soundcard) while this scene is shown.
But as soon as I switch to said scene, OBS crashes - at least as long as I have the Microphone DSP Plugin enabled and your plugin active in the scene as a source.

Here is the Crashlog:

Code: 
OBS has encountered an unhandled exception and has terminated. If you are able to
reproduce this crash, please submit this crash report on the forums at

a description of what you were doing at the time of the crash.

This crash appears to have occured in the 'c:\program files\obs\plugins\obs_mic_dsp-1.1-x64.dll' module.

Hi guys! I can't seem to get asio working with Ableton Live 9. I've messed around with all of the possible settings. I'd like to be able to use an audio interface (Focusrite i2i) while streaming an Ableton Live production session but if i cant that's OK i guess... Has anyone been able to get this to work, if so what combo of settings did you use in OBS's settings and DirectShow's settings? I've tried MME/directx but the latency is really bad.

Thanks!
Sean

Hi, i'm trying to get game audio, music(both over my speakers) and skype(over my headset) in my stream. I can't add my headset to the output sources because obs crashes. Can someone help me?

Playback devices cannot be used with this plugin (see the red text in the info section). I would recommend to use OBS-MP which lets you select more than one audio device by default.

I spent a few hours messing around with this plugin. My goal was to set it up where my broadcast would have music playing that I personally could not hear. So my viewers could be entertained without affecting my focus on teamspeak and gameplay.

I made a short guide on how I made it work, your situation may be entirely different but it could inspire your own solution. Give it a look guys.

So I recently downloaded this pluginand I followed the directions to install it. I couldn't extract directly to my plugins folder for some reason, so I extracted to my downloads folder and moved the files into my plugins folder. Now what? I look in the plugins menu in OBS and the plugin isn't showing up, I can't add an audio source to a scene, like the plugin should let me do. What am I doing wrong?

Did you copy the plugin to the correct OBS install?

If you're using 64 bit OBS and the 64 bit plugin, it needs to be installed to C:\Program Files\OBS\plugins\
If you're using 32 bit OBS and the 32 bit plugin, it needs to be installed to C:\Program Files (x86)\OBS\plugins\

EDIT: Nevermind, it seemed I needed to restart windows audio as Listen to this device wasn't working properly.

Hey all. I had this all working fine until I reinstalled my OS and forgot how I set it up. Any help appreciated.

I have two audio outs, desktop/games/everything on my speakers and then everything voice such as Skype, Teamspeak etc coming out of my headphones. I have VAC Input and Output set up and I can get my OBS to pickup Teamspeak using VAC but then I can't hear it out of my headphones.

Can someone point me in the right direction? Forgot what I did last time to make it work! Thanks very much.

Is there update coming up soon? I'd love to use this plugin for speaker source. I know there is OBS Studio out there, but i don't like it, so I better stay with OBS classic, but still would be pretty awesome to have features of STUDIO OBS. Can you fix this please? :O :)

The plugin author was last online in march 2016, this plugin is also for OBS Classic which means it probably will not see any updates.
OBS Studio comes with the option to add input or output audio device as sources right away.
