# musikcube

a cross-platform audio engine and player written in c++.

# musikbox

a curses frontend to musikcube.

musicbox 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.

it looks something like this on windows:

and this on macos:

and on linux:

you can also stream audio from, or remote control musikbox using the `musikdroid` android app, which can be downloaded in the `releases` section above. it looks like this:

# raspberry pi

want to run musikbox on a raspberry pi, connected to you home stereo? [see here](https://github.com/clangen/musikcube/wiki/raspberry-pi).

# streaming server documentation

if you're interested in writing your own frontend, [api documentation is available here](https://github.com/clangen/musikcube/wiki/remote-api-documentation). the streaming server api uses a combination of websockets and vanilla http, and is included in every `musikbox` distribution.

# compiling

## windows

- grab the [Visual Studio 2017 Community Edition](https://www.visualstudio.com/en-us/downloads/download-visual-studio-vs.aspx) and install the 32-bit c++ compiler.
- clone the musikcube sources: `git clone https://github.com/clangen/musikcube.git`
- install the [32 bit version of boost 1.64](https://sourceforge.net/projects/boost/files/boost-binaries/1.64.0/boost_1_64_0-msvc-14.1-32.exe/download). ensure it shares the same parent directory with musikcube. e.g: `c:\src\musikcube` and `c:\src\boost_1_64_0` -- the project's solution will reference it via relative path.
- open `musikcube.sln` and build/run. 

## mac

you'll need [homebrew](http://brew.sh/) to install the required dependencies. 

### automatic

- `brew tap clangen/musikbox`
- `brew install musikbox`
- `musikbox`

### manual

- `brew install cmake boost libogg libvorbis flac faad2 libmicrohttpd lame`
- `git clone https://github.com/clangen/musikcube.git`
- `cd musikcube`
- `cmake .`
- `make`
- `cd bin`
- `./musikbox`

## linux

- install the following libraries and their development packages: `cmake boost libogg vorbis flac faad2 ncurses zlib asound pulse libcurl libmicrohttpd libmp3lame`
- `git clone https://github.com/clangen/musikcube.git`
- `cd musikcube`
- `cmake .`
- `make`
- `sudo make install`
- `musikbox`

## keyboard shortcuts

the hotkeys listed below can generally be used at any time; however, if an input field is focused some may not work. you can enter command mode by pressing `ESC`, which will highlight the bottom command bar and accept all hotkeys. command mode may be deactivated by pressing `ESC` again.

you may also change hotkeys by editing `~/.musikcube/hotkeys.json` and restarting the app. a hotkey tester is provided in the settings screen.

- `TAB` select next window
- `SHIFT+TAB` select previous window
- `~` switch to console view
- `a` switch to library view
- `s` switch to settings view
- `i` volume up 5%
- `k` volume down 5%
- `m` toggle volume mute
- `j` previous track
- `l` next track
- `u` back 10 seconds
- `o` forward 10 seconds
- `v` show / hide visualizer
- `r` repaint the screen
- `.` toggle repeat mode (off/track/list)
- `,` (un)shuffle play queue
- `CTRL+p` pause/resume (globally)
- `CTRL+x` stop (unload streams, free resources)
- `CTRL+d` quit 

and a couple hotkeys that are specific to the `library` view: 

- `b` show browse view
- `n` show play queue
- `f` show album/artist/genre search
- `t` show track search
- `1` browse by artist
- `2` browse by album
- `3` browse by genre
- `x` jump to playing artist/album/genre in browse view
- `M-ENTER` show a context menu for the currently selected item (album, artist, genre, track)
- `SPACE` pause/resume

these only work in the `play queue` view:

- `M-s` save current queue as a playlist
- `M-l` load a previously saved playlist
- `M-x` delete a previously saved playlist
- `M-r` rename a playlist
- `M-UP` move the selected track up
- `M-DOWN` move the selected track down
- `DEL` delete the selected track

a couple important **notes**:

- on macos make sure you configure your terminal emulator to treat your left alt key as "+Esc" or "Meta"
- `ALT` is the `M`odifier key in the windows build

# 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 refined. you can see what they currently look like here: https://github.com/clangen/musikcube/tree/master/src/core/sdk
