atkAudio Plugin​


PluginHost​

  • VST3 plugin host for OBS
  • MIDI & Sidechaining
  • Direct audio hardware routing
  • Optional multithreading
  • Also AU/LV2 plugins on macOS/Linux

PluginHost2​

  • as PluginHost
  • Build filter graphs (complex signal chains) with multiple plugin instances
  • Internal multithreading
  • Saving and loading of filter graphs as files
  • OBS Source volume MIDI control
  • etc
PluginHost2 can interface directly with audio and MIDI hardware, OBS audio sources, and output audio as new OBS sources, allowing for complex audio processing setups. E.g. use ASIO interface as audio device, take additional audio from OBS sources, route monitoring to ASIO outputs and/or different audio drivers/hardware, use plugins and create final mix, and output the processed audio as a new OBS source for recording and streaming. Or e.g. create OBS audio mixer MIDI controller, or a simple soundboard with a sampler plugin and a MIDI keyboard.

DeviceIo(2)​

  • Send and receive audio directly into and from audio devices
  • "Anything from/to anywhere" device routing
  • ASIO, CoreAudio and Windows Audio devices

Audio Source Mixer (OBS Source)​

  • Mix audio from OBS sources into a new OBS audio source
  • E.g. allows creating new submixes
  • Can be used as 'dummy' audio source e.g. to host DeviceIo or PluginHost2 filters

MIDI Control​

  • In Tools menu
  • Use MIDI controller to control OBS
    • Source Volume, Monitoring and Mute
    • Scene switching
    • Transitions
    • Effect parameters, also in PluginHost(2)
      • Last Touched, with history
    • ...
  • Internal Bank/Preset model
    • Use MIDI to switch between banks/presets
    • Build your own virtual MIDI control surface
  • Some tips
    • Put motorized controller into MIDI mode
    • Absolute for faders/limited range knobs
    • Toggle/Trigger for buttons
      • Absolute for push functions
    • Inc/Dec(2) for endless encoders
      • Lower scale to add more precision

Manual/portable installations​

Extract .dll|.dylib|.so file from installer and copy it to OBS plugins directory. For example on major Linux distros, extract atkaudio-pluginforobs.so from .deb file and copy it to ~/.config/obs-studio/plugins/atkaudio-pluginforobs/bin/64bit/.

So I wanna say that this plugin does work and being able to use VST3 plugins on my audio results in a major noticeable improvement in livestream audio quality. But I have been having an issue since I added this plugin to my obs crashing mid stream which I find unusual. I'm running an AMD Radeon RX 9070 XT which should be strong enough to run this plugin,

If anyone else has this issue or an idea what I should do Id appreciate it cause I would really like to get this working.

hi! Most, if not all, of audio processing is done by CPU. And some realtime audio processing can be very CPU heavy.

For me, this is the REAL DEAL and it might be the only audio plugin anyone will ever need for their audio routing/setup in OBS.

The PluginHost2 is just too powerful of a filter! Once you learn using its simple graph interface and explore the plugin nodes and their routing capabilities on the graph, you'll have a great time making your audio setup for a podcast or music production livestream/recording.

I love how I was able to use DeviceIo2 as a node in PH2. It was so versatile I was able to use it as an extra I/O, its input passthrough like feature and for monitoring and to whatever you want to route it from/to.

Everything is smooth and there's really no issue performance-wise!



P.S.
Just a concern when creating an OBS Output node in PH2. It will automatically make an OBS Source named "Ph2Out" but you won't be able to reroute the Output node to a specific "Ph2Out" source. I realized this when it was possible to add another OBS Output node which was then named "Ph2Out 2". I don't know if it's supposed to be like that but if it is, I guess it's good for me to have a single graph with, for example, a preset for a vocal and instrument mix.

Very powerful and well-designed audio plugin for OBS. You can:

- Load VST3/AU plugins directly inside OBS
- Create submixes or a master bus for your audio sources
- Have audio routing with low latency
- Have audio matrix for flexible routing (juste like Loopback or Voicemeeter Banana)

It’s especially useful for live streaming and podcast workflows. The plugin is clearly built with real audio use cases in mind and has become an essential part of my setup. I’m sure the developer will add this in the future, but for now, the only feature I’d still love to see is the ability to monitor audio even when a source is not in the program scene.

Excellent plugin for anyone that wants to combine multiple audio sources inside OBS and stream them as one track!

This is the best audio plugin ever written for OBS. It flawlessly blends ASIO tools and the ability to use powerful plugins. This dev is the obs allstar of the year

Insanely powerful plugin, the ability for VST3 alone is huge (only other solutions are super janky or a heavy proprietary app that's windows/mac only).

The fact that you can entirely re-route OBS audio and avoid some of the pitfalls of the way it handles things as well as have actual submixes or an actual master track to apply filters and stuff to is CRAZY!

I can also tell I'm only really scratching the surface here and need to learn significantly more to truly utilize this gem.

Thanks! It's a kind of "from audio people to audio people" project, so nice to know it's working for you.

This plugin is excellent. The best way to load standard Audio Unit (macOS) or VST3 plugins into OBS. Before this plugin, the only way to achieve this was to use tools like Element from Kushview as a plugin host with the native OBS SVT2 plugin filter.
This plugin makes it much easier. It works also quite reliable. There were some glitches in between, but they were fixed with updates even before I could make an error report.
The GUI of this plugin is also better than the VST2 plugin version of OBS and it even allows for directly selecting a side chain from any OBS source. Wonderful.
The ATK device IO works for me better even than Exeldro's audio monitor. Less audio glitches when the CPU has some more work to do and on Windows there seem to be less problems when the audio source gets restarted (TV, XR18 etc.).
I haven't used the ATK mixer function a lot, as well as the newer ATK plugin 2 (patch bay) version, so I can't make any review on these functions.

I suggest this ATK filter to everybody who wants to improve their audio quality in OBS, it can take it to the next level, while still being quick and easy to use (compared to using an extra VST2 plugin host). Definitely worth leaving some donations for on their website, although, unfortunately, it only allows for a monthly/yearly donation subscription instead of a one-time donation. Maybe they change this in the future.

BTW:
In the current screenshots of this plugin, the author included the Audio Unit plugin "AUSoundIsolation" (from Apple, only available on MacOS).
This is a very good option for voice isolation. It removes background noise and even reverb from vocal content.
We use this A LOT, on every single microphone we are using in our setup. Very low CPU usage compared to Waves Clarity VX and similar plugins while keeping the original voice unmodified as in contrast to Accentize DXRevive or (even worse) the Crumplepop voice enhancer. Less artifacts than the OBS build-in noise reduction options (when used below 95% in AUSoundIsolation - don't set it to 100%) or Bertom Denoise. But it adds around 40ms extra latency, which is kind of standard for this kind of plugins (except Bertom etc).

Thank you for your review, hatibo3504. Glad to hear the plugin has been useful. Feel free to take Plugin Host2 to the range. Plugin Host2 also allows you to basically bypass OBS for software-based audio monitoring. Options > Change Device Settings and switch driver from OBS to e.g. ASIO/CoreAudio. Audio Input and Audio Output modules are now directly connected to selected device driver. Build your mix and routings etc. Add plugins. Use Device Io to input|output audio from|to other device drivers. Use OBS Source module to read audio input from regular OBS Sources, e.g. Window Capture. Finally, add OBS Output module and route your 'final mix' to it. OBS Output module shows as regular audio source Ph2OutN in OBS audio mixer, and ensure this is your only active source for stream/recording output. So, Plugin Host2 combines Plugin Host, Device Io and Source Mixer into one graph interface plus adds extensive routing capabilities and direct access to audio devices.

Also needed to show some love for this plugin. I use a lot of programs in tandem with OBS in order to do music creation and process my mic, but being able to load VST3 and even get access to my audio hardware inside OBS is a MASSIVE help.

No real issues yet, and stable performance so far!

I just had to login to leave a review and say thank you for actually making an Audio Plugin system that can actually loads VST3 (and so much more) with a proper UI. You're a hero. So far I haven't encountered any serious issues it seems like.
