[RELEASED] JACK4U - Route audio from a DAW to Unity with JACK Audio

Hello Unity Community. We are happy to anounce the release of our new Asset :

JACK4U


With JACK4U you can route the audio data from any ASIO capable Digital Audio Workstation (Ableton Live, NI Traktor, Pure Data...) to Unity with the JACK Audio System (Windows only atm. Requires Unity Pro)
​

A first video should show you what is possible with JACK4U in combination with Ableton Live:

​

Here is a video that shows the installation process and setup:

Any feedback is welcome!

great

 

Just uploaded a video that shows the installation process and setup.

 

JACK4U is finally released on the Assetstore !

Submitted version 1.1:

• Unity 5 support

- PortAudio plugin structure changed to x86/x86_64
- added a 64 Bit version of the PortAudio.dll
- removed the options for Sample Rate, DSPBuffer and DSP Buffers as this is now handled via the
AudioSettings from your Unity Project
- The AudioListener is now attached to the main camera as you can't have an AudioSource and an
AudioListener on the same GameObject if you use a custom DSP filter script.​

• Documentation update

Unity 5 changes the way of some audio related settings. You can't set the DSPBuffer settings and the Sample Rate anymore on the component. You have to go to the AudioSettings under 'Edit/Project Settings/Audio' to set the Sample Rate! (Windows uses 48000 per default), so if you have problems with your audio please check this.
You also have to remove any Audio Listener that are on your JACK4UConnection gameobject.(It will work in the editor, but when you publish an app there will be a console messages that this doesn't work anymore when you use custom DSP filter scripts.)

Until now i had some missconception about the way the JACK system works with ASIO soundcards. I changed the documentation so you now should be able to route the audio to your ASIO soundcard when using JACK4U.

 

We got the JACK4U asset, but we're unable to get spacial 3D working.

With a regular AudioSource you can hear it pan from side to side depending on where it's located relative to the camera, with JACK4U-AudioSource the volume for both channels decreases/increases but there's no panning. Is there a setting somewhere that allows it to behave like a regular 3D AudioSource?

 

Hi,
it seems that this is an old Unity issue . I investigate this to get a solution.

 

If I don't enable the JACK4U Connection script, the audio source (with an audio clip) is played using spatial 3D. Not sure how the old Unity issue applies. I've also tried to use a DSP spatializer plugin (3Dception by TwoBigEars) which works properly (applying binaural effects) using an audio clip, but not with JACK4U.

 

Thanks to @Nifflas there is a little hack .
In the next version i will make some tiny modification that when you have attached an AudioClip to your AudioSource it will multiply the values.

 

Hello, i wanted to know if with this asset i can pick up a guitar link input usin ASIO drivers?

 

I'm not familiar with routing instruments into the audio chain but if you use Ableton Live for example and manage to get the signal from your guitar into the mixer then it should be no problem as the output from Live could be routed via JACK to Unity

 

This looks very cool, any chance of Mac support in the future?

 

Sorry at the moment i have no plans for Mac support. But i added a poll to get feedback if there is a interest.

 

Hello,
looks good,
Is it possible to use it the other way around :
To get the Unity audio in JACK and to redirect it to an software/audio card?

Thanks

 

Hi,
you can only pass through the audio that comes from JACK into Unity to another JACK receiver, but you can't sent the Audio that is created in Unity.

 

Thanks for the quick reply !

 

Is it possible with JACK4U to have multiple live audio inputs in Unity? So if I wanted to visualize the vocals separate from the guitar using Visualizer Studio for instance, I could have 2 different inputs and independently visualize each audiosource?

 

Unfortunately you can only route one stereo input into Unity. I didn't managed to read more channels without problems.

 

Theoretically could I create multiple client instances of an app that has JACK4U (similar to your YouTube sample) and connect all of them to a local "server" Unity client that collects all the data streams and visualizes them?

 

Hello monoflow

I want to use JACK4U to retrieve the audio of my mic in realtime with no latency on Unity.
I need to connect Jack Audio to the system and start it.
But as soon as I use a frame/period under 1024, the audio is glitchy. Do you know an idea why the problem occurs? (Unity 5.5.1f1)

 

Do you have a lot of processes running on the machine? To get the best settings without any glitch you have to carefully tune your system so that only the essential processes are runing (stop all programms and background processes that are not necessary) But it could also depend on your CPU power.

 

I made some tests and I became able to use it (dont't really know what I really do). But even if I set the frame/period to 64, I always have a small latency when I use the mic. Can I have zero latency or my hardware ?

UPDATE :
Now the connection seems to dont work anymore. Jack4U connection send the error message : Queue Full!

here my settings :

 

Do you have an example of using JACK4U with puredata on Windows?

 

I suddenly had this problem too after having everything work for a while. Did you find a solution?

 

Each time I had the "Queue Full" Error, I needed to kill all process relate to jack4u. Then I reloaded my app.

 

Dos this plugin support asio output for low latency audio in games? I don't think this is clear by the discription..

 

I am a REASON (DAW) user.
I have some trouble in developing a music game..
I wonder this asset can help me or not...
like most of music or rhythm game.
When background music starts to play.All of the notes go forward to target where the player will press the button in right bit time.
Sometimes this notes arrive in times.Sometimes overhead...and Sometimes they are not fast enough...
How can fix the issue?? This asset will be helpful??any guys ??any solution??

 

Is this asset dead? I added a new connection, start the jack server, and press play in unity... but unity crashes.

 

I just bought this asset and tried running it with unity 2019.3.0b12 and it keeps crashing everytime I play the example scene. Can I get some help? Was really looking forward to using this, would be totally worth the price if I can get it running.
