musikcube

a cross-platform, terminal-based audio engine, library, player and server written in c++.

musikcube compiles and runs easily on windows, macos and linux. it also runs well on a raspberry pi with raspbian, and can be setup as a streaming audio server.

check out the installation guide to get up and running.

be sure to also read through a the user guide, which describes app's navigation paradigm and lists all the default keyboard shortcuts.

screenshots

it looks something like this on windows:

and this on macos:

and on linux:

here's a demo (made with asciinema):

while the main musikcube app runs in the console, you can also stream audio from (and even remote control) musikcube using the musikdroid android app, which can be downloaded in the releases section above. it looks like this:

installation

binaries are available in the releases page.

while macos binaries are provided, you can also install via homebrew as follows:

• brew tap clangen/musikcube
• brew install musikcube
• musikcube

raspberry pi

musikcube runs well on a raspberry pi, connected to you home stereo. see here for detailed setup instructions.

compiling

if you'd like to compile the project yourself, you can check out the build instructions.

keyboard shortcuts

a list of all keyboard shortcuts can be found in the user guide

streaming server

musikcube ships with a streaming audio server enabled by default. it runs a websocket server on port 7905, used for metadata retrieval. an http server runs on port 7906, and is used to serve (optionally transcoded) audio data to clients.

it's important to understand that, out of the box, the server (and remote api) should NOT be considered safe for use outside of a local network. the websockets service only supports a simple password challenge, and the audio http server just handles Basic authorization. it does not provide ssl or tls. the server also stores the password in plain text in a settings file on the local machine.

you can fix some of this using a reverse proxy to provide ssl termination. details in the ssl-server-setup section. while this improves things, you should exercise caution exposing these services over the internet.

if you're interested in writing your own frontend, api documentation is available here.

sdk

the musikcube sdk is a set of small, pure-virtual c++ classes and a handful of enums and constants. they're still in the process of being slimmed down. you can see what they currently look like here: https://github.com/clangen/musikcube/tree/master/src/core/sdk
