Music Synchronization And Uniform Relaying

---

Update 08/09/2016: Version 1.5 released!

• Updated to the latest version of caddy
• Updated to latest version of howler.js

---

Want to sync up your music on multiple computers? This accomplishes exactly that - using only a simple program and a browser. Simply run the program, and open up a browser on each computer you want to sync up - that's it!

This program is powered by the excellent howler.js library from goldfire. Essentially all the client computers sync their clocks and then try to start a song at the same time. Any dissimilarities between playback are also fixed, because the clients will automatically seek to the position of the server.

Tested on Android, Windows phone, Windows, OS X, and Linux.

Setup

If you don't want to install anything, just download the compiled version. Otherwise, read on ->.

git clone https://github.com/schollz/musicsaur.git
cd musicsaur
go get ./...
go build

Then copy the configuration file

cp config-go.cfg config.cfg

and edit line #5 with your music folders. Then simpily use

./musicsaur

to start up the server!

I suggest using ffmpeg as it will make syncing much faster. Installation is easy:

sudo add-apt-repository ppa:mc3man/trusty-media
sudo apt-get update
sudo apt-get install ffmpeg

Some notes

• If you don't hear anything, the client is probably trying to synchronize. The browser automatically mutes when it goes out of sync to avoid the headache caused by mis-aligned audio. You can see synchronization progress in your browser console.
• If you still dont' hear anything, and you're using Chrome browser on Android you need change one of the flags in chrome to allow audio without gestures. To do this, copy and paste this into your Chrome browser:

chrome://flags/#disable-gesture-requirement-for-media-playback

• If you want to play music from a Raspberry Pi, just type this command (works on headless):

xinit /usr/bin/midori -a http://W.X.Y.Z:5000

OR

xinit /usr/bin/luakit -u http://W.X.Y.Z:5000
