Setting up the System

Python Dependencies

pip3 install oscpy

SuperCollider

1: Build and install SC

2: Build a headless version of SC:

Follow https://github.com/supercollider/supercollider/blob/develop/README_LINUX.md but call cmake:

cmake -DCMAKE_BUILD_TYPE=Release -DNATIVE=ON -DSC_EL=no -DSC_ABLETON_LINK=off -NO_X11=ON -DSC_QT=OFF ..

Install SC3-Plugins:

https://github.com/supercollider/sc3-plugins

Install SC-HOA classes:

Quarks.install("https://github.com/florian-grond/SC-HOA")

Build Faust Reverb

Faust code for the Ambisonics reverb is located in Faust/reverb. The install script builds and installs the SuperCollider class and objects to the user extensions directory. Make sure install ruby before using the Faust to SC compiler.

Developer Mode

The scripts supercollider_gui.sh and supercollider_nogui.sh allow to switch between the standard SC install and the headless version by setting symlinks in /usr/local/bin

Once the standard version is lionked, scide can be started for development and debugging.

Seamless installation

For the installation of SeamLess the Meson build system is used.

Create build directory: 

meson builddir

Set SeamLess location (e.g. EN325, HUFO): 

cd builddir
meson configure -Dlocation=HUFO

Installation: 

sudo meson install

Create symlink to specific snapshot: 

cd /etc/seamless
ln -s snapshots/wfs1.snap aj_snapshot_config.xml

WONDER installation

WONDER also uses Meson.

meson builddir
cd builddir
meson configure -Dlocation=HUFO
meson compile
sudo meson install

Disable unneeded things

Turn off dbus activated jack

For using the seamless_jack system service it might be necessary to turn off the dbus activated jack daemon: 

jack_control stop

Comment out jackdbus auto in /usr/share/dbus-1/services/org.jackaudio.service: 

[D-BUS Service]
Name=org.jackaudio.service
#Exec=/usr/bin/jackdbus auto

Turn off pulseaudio

Pulseaudio runs as user service and should be masked.

systemctl --user stop pulseaudio.socket
systemctl --user stop pulseaudio.service
systemctl --user mask pulseaudio.socket
systemctl --user mask pulseaudio.service

Disable Automatic Updates

Automatic updates are not desired, since they can change the system behavior. In addition can disable the DANTE drivers.

Edit:

/etc/apt/apt.conf.d/20auto-upgrades

It needs to be:

APT::Periodic::Update-Package-Lists "0";
APT::Periodic::Download-Upgradeable-Packages "0";
APT::Periodic::AutocleanInterval "0";
APT::Periodic::Unattended-Upgrade "0";

Turn off graphical user interface

sudo systemctl set-default multi-user

Add user to audio group

Add the user to the audio group: 

audio:x:29:pulse,user
