Loading

• Select an input mix track to create an audio source
• The audio source uses the selected mix track as input and allows various filters to be applied
• Allows selection of mix tracks as output, excluding the mix track selected as input
• Buffering causes a minimum delay of 1024 samples (21 ms at 48 kHz)
  • If even greater delay is unacceptable, enable Low Latency Buffering Mode in OBS Settings > Audio > Advanced

Install

Please download the archive file from the Releases page.

Windows

After extracting the archive file, place the mix-track-to-source folder in the following location:

C:\ProgramData\obs-studio\plugins

Run the mix-track-to-source-<version>-macos-universal.pkg file to install it.

Ubuntu

Run the following command:

sudo dpkg -i mix-track-to-source-<version>-x86_64-linux-gnu.deb

Usage

• Add Source > Mix Track to add an audio source
• Select a mix track to use for input from Track 1 to Track 6
• Select outputs for added audio track in the Advanced Audio Properties window
  • Cannot select the same track for both input and output
  • Deselect the output from other sources as needed

Usage example

After applying a limiter to the input on Track 1, the settings for outputting the audio to Track 6 for distribution are as follows:

• When adding an audio source, set the input to Track 1
• Add a limiter to the filter of that audio source
• Enable the output of Track 6 for that audio source and disable the output to Track 6 for other audio sources
• Select Track 6 in Settings > Output > Streaming > Streaming Settings > Audio Track
