# 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](https://github.com/clangen/musikcube/wiki/installing) to get up and running.

be sure to also read through a [the user guide](https://github.com/clangen/musikcube/wiki/user-guide), which describes app's navigation paradigm and lists all the default keyboard shortcuts.

if you want to build it from source, [the instructions are here](https://github.com/clangen/musikcube/wiki/building).

# 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](https://github.com/clangen/musikcube/releases) page.

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

- `brew tap clangen/musikcube`
- `brew install musikcube`
- `musikcube`

on freebsd musikcube can be installed as follows:

- `pkg install musikcube`

on windows, you can install via chocolatey:

- `choco install musikcube`

then run using shell, Win+R dialog or by typing in Start Menu `musikcube` or `mcube`.

# raspberry pi

musikcube runs well on a raspberry pi, connected to your home stereo. [see here for detailed setup instructions](https://github.com/clangen/musikcube/wiki/raspberry-pi).

# compiling

if you'd like to compile the project yourself, you can check out the [build instructions](https://github.com/clangen/musikcube/wiki/building).

# keyboard shortcuts

a list of all keyboard shortcuts can be found in the [user guide](https://github.com/clangen/musikcube/wiki/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](https://github.com/clangen/musikcube/wiki/ssl-server-setup). 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](https://github.com/clangen/musikcube/wiki/remote-api-documentation).

# 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/musikcore/sdk

# dependencies

musikcube would not be possible without the following excellent free, open source, and (in the case of some macos and win32 APIs) non-free projects and libraries:
