Installation guide

  • Register on
  • Once registered log in and click on Download tab
  • Download either windows or Mac OS depending on your system. Win users will need an ASIO sound device. If not existing please download the ASIO4ALL driver as well and install it:
  • Extract and open the downloaded file.
  • Run the soundjack application by doubleclicking on the binary file (Win: soundjack.exe / OSX: - Important: A small XLR Icon in your dock will show up. This confirms the soundjack engine is running and working fine. On Windows you will see an additional DOS-type console.
  • Once the plugin is running on your machine return to the sound jack website and click the stage tab



  • Once you have successfully ran the application you will need to set your drivers/settings within the web browser. This may take some tweaking.
  • Select your current driver IN/OUT (on Windows for most it will likely be some form of ASIO driver)
  • Select a Sample Buffer (If you’re experiencing audio issues try raising the sample size to the next higher)
  • Select send channels. These should correlate to the inputs of your interface. Example inputs 1+2 would use 2 send channels. If you had a mic on in1 and a guitar on in3 you’d most likely need to select 4 channels here.
  • Lastly choose your network buffer and OPUS bit rate. The higher the OPUS bit rate the higher the quality but subsequently the more data will be transmitted which could cause issues with slowing internet connections.


Lower network buffers will lower latency but could also create issues with streaming quality. Network buffers will correspond to peers’ sample buffer. For example, if they have a higher sample buffer (512 for instance) you may not need as large of a network buffer your end (perhaps 128). The opposite would also be true if the sender is sending smaller packets (say 128) the network buffer may need to be increased. Unfortunately, due to the nature of the internet and individual hardware setups, there is no straight forward way to determine the optimal settings for everyone so you are encouraged to tweak these settings to find out what works best for your session. OPUS bit rate in short the higher the bit rate the better quality the audio. Linear is uncompressed. 96 kbps is compressed by a factor of 8, 48 kbps by a factor of 16 etc. One thing to keep in mind is that this is the quality of each individual track so the more tracks you have sending the greater the speed requirements. Example one track at 96 kbps will be sending as much information as 4 tracks at 24 kbps.

Apart from this you can communicate what your problem is right in this chat.

Functionality correlates with the user's knowledge of what he/she is doing with the system.

hey guys

stringer - 16:11

thank you Dr. Alex

Sometimes the server receives SIP messages, which belong to VoIP calls. After the reception the server thread is blocked and I currently cannot tell why this happens. Have some ideas though-will try.

JamTuner - 07:20

mysterious, ? Can you explain a little ?

JamTuner - 07:19

thanks , Alex

jazzalex - 06:04

Strange howerver, the reason for the shutdown is really mysterious - need to verify. Thanks for reporting.

jazzalex - 06:03

Hi guys, this happens when one of the servers stops working. Restarted - all fine now.

stringer - 04:04

I'm lie musicmann... can log in but crashes on trying to connect

JamTuner - 04:04

yep. alex should be awake . lets hope to hear from him

stringer - 04:03

tried firefox and chrome

JamTuner - 04:01

every time someone tries connecting sj client crashes

stringer - 04:01

hi alex... app crashing continuously

Musicmann - 04:00

tried chrome and safari same issuwe

stringer - 04:00

no go lol

JamTuner - 03:59

crashed me

Musicmann - 03:59


Musicmann - 02:08

back to jk for

Musicmann - 02:07

Hi Alex...looks Like Andy and attempt to connect

stringer - 02:06

not working lol
