Building

mkdir build && cd build
cmake ..
make
sudo make install

Requirements

• C++17 compatible compiler (GCC 7+, Clang 5+)
• CMake 3.15+
• JACK Audio Connection Kit
• LADSPA DeepFilerNet SDK (optional, for more roubust noise removal)

Usage

Run tpipe from the command line to initialize the JACK node. Currently, the application only creates a stereo audio interface.

tpipe [options]

Options

• -c, --config <path>: Specify a custom path to a configuration file. (Defaults to /etc/tpipe/default.conf if omitted).
• -h, --help: Display the help menu and exit.

Routing Audio

Once tpipe is running, it will appear as a node within your JACK graph. To route audio, you can use a connection manager like QJackCtl:

1. Open the Graph/Patchbay in QJackCtl.
2. Input: Connect an audio capture source (such as your Microphone) and audio from any application to the tpipe input node.
3. Output: Direct the tpipe output node to your desired playback device (such as System Output) or another application.
