raveberry 0.9.0

A multi-user music server with a focus on participation

Raveberry

Raveberry is a multi user music server that allows democratic selection of songs.

It provides an intuitive interface for requesting songs and changing their order according to the rating that users have made. It supports YouTube, Spotify, Soundcloud and local files as sources for music.

A live demo is available at https://demo.raveberry.party/.

Installation

Try it out!

You can test a slim version of Raveberry like this:

sudo apt-get install -y python3-pip mopidy redis-server ffmpeg gstreamer1.0-plugins-bad
pip3 install raveberry[run]
raveberry run

You might need to write ~/.local/bin/raveberry run instead. Now you can visit http://localhost:8080/ and play a song of your choice.

This method uses a development server, with limited performance and a restricted feature set.

Installation

In order to gain access to all features of Raveberry, perform a system installation:

pip3 install raveberry[install]
raveberry system-install

If you get raveberry: command not found you need to run export PATH="$HOME/.local/bin:$PATH". Raveberry was developed for the Raspberry Pi. If you need help setting yours up up, visit this guide.

The installer will ask you to confirm the config file it uses. The default install supports YouTube and local files. To customize (e.g. to use Spotify), cancel the installation, edit the config at the provided path and rerun raveberry system-install.

Although everything should work fine, I recommend taking a backup of your system. On a Raspberry Pi this can be done by creating a copy of its SD card.

The installation will take at most 30 minutes, most of which is spent on installing/updating packages. You might need to reboot afterwards for all changes to take effect.

Docker

Alternatively, you can use docker-compose:

wget https://raw.githubusercontent.com/raveberry/raveberry/master/docker-compose.yml
docker-compose up -d

For more information, consult docs/docker.md.

Remote Installation

You can also install Raveberry on a remote machine you have ssh access to:

pip3 install raveberry[install]
cd "$(pip3 show pi3d | grep Location: | sed 's/.*: //')/raveberry"
ansible-playbook --user <user> --key-file <private_key> -i <ip>, -e "config_file=/path/to/raveberry.yaml" setup/system_install.yaml

If omitted, config_file defaults to config/raveberry.yaml. --user and --key-file can be omitted if the target host is configured in your ssh config.

Passwordless sudo is default on a Raspberry Pi. For most other systems, sudo requires a password, then you have to add --ask-become-pass.

First Steps

After the installation has finished http://raveberry.local/ is up and ready to play music (go ahead and try now!). If this does not take you to the musiq landing page, use the IP of the device (hostname -I to find out).

You can visit http://raveberry.local/login/ and log in as the admin user with your provided admin password. If you take a look at http://raveberry.local/settings (which is also linked from the dropdown) you can see various configuration possibilities. For more information about these settings and privileges in general refer to docs/privileges.md.

An introduction to basic functionality can be found in docs/functionality.md. Or just visit find out for yourself ; )

Updating

Webinterface

At the bottom of the /settings page, click "Upgrade Raveberry". A Log will be written to /var/www.

Manual

Update the PyPi package and rerun the system installation.

pip3 install -U raveberry[install]
raveberry system-install

Your database will be preserved, unless you specify a database backup in your config file.

Docker

Update all of your containers in the docker-compose file:

docker-compose pull

Features

• Live Updates: Web page content is updated instantly using websockets.

• Remote Streaming: With icecast, it is possible to remotely listen to Raveberry. See docs/streaming.md.

• Bluetooth Support: Use your bluetooth speakers with Raveberry, removing the need for an audio cable.

• HiFiBerry Support: Attach your HiFiBerry board for a high quality audio experience.

• Hotspot: Provides a WiFi network for access in areas without proper infrastructure. Can double as a repeater.

• Remote URL: Specify a domain to make your Raveberry accessible from the world wide web.

• Local Files Support: Play all the files you already have in your local filesystem. Various filetypes supported.

• YouTube Support: With youtube-dl as a media provider, all of YouTube is available to play.

• Spotify Support: Raveberry's music player mopidy can play songs from Spotify, if you to log in with your account. Spotify Premium is required.

• Soundcloud Support: Songs from Soundcloud are also available for you to play.

• Privilege Levels: Grant people additional permissions like playback control.

• Graphical Admin Interface: Raveberry features a convenient way of modifying the behavior of the server, like hotspot configuration or download limitation.

• Complementary App: Shareberry lets you share songs directly from your phone to Raveberry.

• Discord Integration: Control your Raveberry instance from the discord chat with the Raveberry bot

• Audio normalization: Raveberry uses replaygain to analyze the volume of songs and prevent sharp volume transitions.

• Screen visualization: With the tool cava, the current music is split into its frequencies and visualized on a connected screen (See screenshot below). Can also be configured to run in user mode.

• Audio visualization: Using the same tool, Raveberry can also make connected LEDs flash to the rhythm of the music.

Optional Hardware Additions

Some of Raveberry's features rely on additional hardware. If you want to use all of them, consider upgrading your Raspberry Pi with one of these one of items:

• WiFi Dongle: To provide a WiFi network for users to connect, you have to set up a second network interface. If disabled, your users have to be in the same network as Raveberry, or you have to configure an external URL.

• LEDs: For audio visualization, Raveberry uses the i2c and spi protocols to control connected LEDs. They will automatically be used if they are detected at server startup. For more information see docs/leds.md.

• USB Sound Card: The quality of the internal Raspberry Pi sound card varies from model to model. For a better music experience I recommend using a small USB sound card.

• USB Stick: If you don't want to use the Raspberry Pi's internal filesystem, you can insert an external medium like a USB stick. Its label can be specified in the config file and is then used to cache the songs.

Tested Hardware

Raveberry is known to work on the following Hardware:

• Raspberry Pi 4
• Raspberry Pi 3B+
• Raspberry Pi Zero W

If you have something to add to the list, please let me know!

Although it is possible to install and run Raveberry on the original Raspberry Pi (after a very long installation), the hardware is just to weak for audio decoding and can not provide a pleasant experience at all.

Uninstall

During installation a backup folder is created. It contains all files that were overwritten outside of the raveberry/ folder. To undo installation, move these files back to their respective locations using the following command. Take care of changes you made in the meantime!

sudo cp -r backup_{timestamp}/* / 

To remove files created during the setup run

sudo scripts/uninstall.sh

FAQ

Where are my YouTube files?

If you specified a path in your config file before installing, you will find them there. If no path was given, it will default to ~/Music/raveberry. If you run it as pi using raveberry run, this will be /home/pi/Music/raveberry. If Raveberry was installed on the system, the process is running as www-data and you will find the directory at /var/www/Music/raveberry.

Streaming doesn't work (there is only silence)

This is a known issue on Ubuntu 20.04. To fix it, downgrade libshout3:

cd /tmp
wget http://mirrors.kernel.org/ubuntu/pool/main/libs/libshout/libshout3_2.4.1-2build1_amd64.deb
sudo dpkg -i libshout3_2.4.1-2build1_amd64.deb
sudo apt-mark hold libshout3

I want to use the visualization without doing a system install.

Install the required python packages

pip3 install raveberry[screenvis]

Install cava (Instructions from the repository)

sudo apt-get install git libfftw3-dev libasound2-dev libncursesw5-dev libpulse-dev libtool automake libiniparser-dev
export CPPFLAGS=-I/usr/include/iniparser
git clone https://github.com/karlstav/cava
cd cava
./autogen.sh
./configure
make
cp cava ~/.local/bin  # or add the binary to your PATH

comment out the following line in the used cava config (add the #):

# source = cava.monitor

Now you should be able to start the server with raveberry run, login with admin:admin at localhost:8080/login and enable the visualization at localhost:8080/lights.
