OS X WiFi Volume Remote
A web-based html5 / node.js app to control OS X system volume from iPhone, Android, etc
Installation & Usage
-
Get Node.js
-
Open Terminal
-
Install
osx-wifi-volume-remote
like sonpm install -g osx-wifi-volume-remote
-
Start the server like so (and note that it shows the name of your computer)
osx-wifi-volume-server 4040
-
Type the
http://<your-computer-name>.local:4040/
whatever onto your phone's browser (NOTE: Your phone or whatever device must be on the same WiFi or ethernet network as your computer) -
Enjoy controlling your MacBook's volume over wifi!
API Example
npm install osx-wifi-volume-remote
(function () {
"use strict";
var applvol = require("osx-wifi-volume-remote");
// All callbacks have the same arguments
applvol.get(function (err, volume, muted) {
console.log(
"Volume is set to " +
volume +
"% and is " +
(muted ? "" : "not ") +
"muted"
);
});
})();
API
get(cb)
read the current volume level and mute statusfade(cb, level, duration)
specify a volume level to fade tofadeBy(cb, difference, duration)
specify a positive or negative difference in volume to fade tomute(cb, duration)
fades to 0, mutes, then restores volume while mutedunmute(cb, duration)
sets volume to 0, unmutes, then fades back in to volume levelset(cb, level)
hard set a volume without fading- all callbacks have the arguments
err, volume, muted
NOTE: The callbacks all must come first (it was just easier to write the code that way).
Development
If you want to develop, here's the clone and build process:
git clone https://github.com/coolaj86/osx-wifi-volume-remote.git
pushd osx-wifi-volume-remote
npm install -g jade
jade browser/index.jade; mv browser/index.html public/
npm install
node app 4040
AppleScript
I had to learn a bit of AppleScript to get this all together. I'll give the gist of it below an you can also read the article on my blog.
# Check volume level and mute status
osascript -e "output volume of (get volume settings) & output muted of (get volume settings)"
# Mute
osascript -e "set volume with output muted"
# Unmute
osascript -e "set volume without output muted"
# Mute status
osascript -e "output muted of (get volume settings)"
# Set volume by 100ths
osascript -e "set volume output volume 51 --100%"
# Set to 0% without muting (the secret lowest possible setting)
osascript -e "set volume without output muted output volume 0 --100%"
# Set to non-0 without unmuting
osascript -e "set volume with output muted output volume 42 --100%"
# Decrement the current volume by 1
osascript -e "set volume output volume (output volume of (get volume settings) - 1) --100%"
It turns out that AppleScript takes about 80ms to start up and run, so for the fade I actually create a file with the whole loop unrolled and it looks like this:
set volume without output muted output volume 18 --100%
delay 0.033
set volume without output muted output volume 17 --100%
delay 0.033
set volume without output muted output volume 16 --100%
