# DESCRIPTION

Beast is a digital synthesizer and music creation system. It has support
for Linux Audio Plugins
([LADSPA](http://wikipedia.org/wiki/LADSPA)),
multi-track editing, unlimited undo, real-time synthesis, MIDI and various
free audio codecs.
Bse is the Beast Sound Engine, a library providing the synthesis and
audio functions used by Beast.

# REQUIREMENTS

Beast is a soft realtime application which needs elevated CPU scheduling
priorities to avoid audio glitches and drop outs. For this purpose, it
installs a small uid wrapper which acquires nice level -20 for the
synthesis threads and then immediately drops privileges.
For Linux kernels of the 2.6.x series and later, this enables the
low-latency scheduling behavior needed to avoid audio artefacts.

In order to build release tarballs, `Rapicorn`, `GnomeCanvas`,
`Ogg/Vorbis`, `libflac` and `npm` are required.
Support for MP3 files is optional and requires `libmad` (MPEG audio
decoder library) when compiling Beast.
Compilation requires `g++-5.2.1` or later and a recent Linux
distribution like Ubuntu-14.04.


# INSTALLATION

In short, Beast needs to be built and installed with:

	./configure
	make
	make check         # run simple unit tests
	make install
	make installcheck  # run audio tests

Note that Beast has to be fully installed to function properly, and that
the binaries built in the launchers/ directory have to be installed with
permissions of the root user.

# BINARY PACKAGES

New source code pushed to the Beast repository is automatically built
and tested via Travis-CI. Ever so often we create release candidate
packages and later release packages after a stabilization phase.
Some of the release candidates and the stable versions are provided
as binary packages which can be installed via apt:

    # Enable HTTPS transports for apt
    apt-get -y install apt-transport-https ca-certificates wget
	# Recognize signatures from the Beast-Team
	wget -qO- https://beast.testbit.org/apt/archive.key | sudo apt-key add -
    # Add Beast release packages to the repository list
    echo "deb https://beast.testbit.org/apt xenial/stable/" |
      sudo tee -a /etc/apt/sources.list.d/beast-team.list
    # Update package list and install Beast
    apt-get update && apt-get -y install beast

The directory `xenial/stable/` holds end user release packages, and
the directory `xenial/rc/` holds temporary release candidates.
