Project: Change AirPlay Speakers, Change EQ

I don't fiddle much with iTunes EQ settings. I most frequently send audio to a receiver and, if necessary, tweak the tone settings there. But I realised that if you're using AirPlay, you may want a different EQ setting for a selected AirPlay device. If you don't mind firing a script whenever you want to change AirPlay speakers—and you don't mind doing some of the script-writing yourself—here's a simple way to acomplish that.

And I do mean simple. This script is pretty basic and could be finessed much more thoroughly. It will only allow you to select a single AirPlay device (I don't believe there can be a different EQ for each active AirPlay device simultaneously) but it'll get the job done.

Here's the script. Open it in AppleScript Editor:

tell application "iTunes"

set listOfAirPlayNames to (get name of every AirPlay device)

set chosenAirPlayName to (choose from list listOfAirPlayNames with prompt "Change AirPlay Speakers to:")

if chosenAirPlayName is false then return -- user pressed Cancel

set chosenAirPlayName to (chosenAirPlayName as text) -- coerce to text from list

# This is the part you have to code:

if chosenAirPlayName is "Computer" then set chosenEQName to "Rock"

if chosenAirPlayName is "Apple TV" then set chosenEQName to "My Customized EQ"

if chosenAirPlayName is "Bedroom Airport Express" then set chosenEQName to "Classical"

# and so on...

# apply the changes

set current AirPlay devices to AirPlay device chosenAirPlayName

set current EQ preset to EQ preset chosenEQName

end tell

You will have to supply the names of your AirPlay devices and the name of the EQ setting you want to use with each. The latter is easy, just use the name of an EQ preset as it's displayed in the Equalizer Window. To get the accurate names of the Airplay devices, just run the script from AppleScript Editor and then right away click the "Cancel" button in the choose list dialog. In the AppleScript Editor Event Log window you'll see the names listed. Use these names in each of the repeating lines of code in the script. You may have fewer or more than the three example lines in the original script. Edit accordingly.

When those edits have been made, "Save" the script as "Script" and named whatever you like and saved in your [home]/Library/iTunes/Scripts/ folder. And, like my Mom always says, add a keyboard shortcut to launch it.

Remember: if you manually change your AirPlay speakers in iTunes, without using the script, the EQ will not change. That only happens when you run the script.

So also: smarties can probably figure out how to set a discrete volume for each chosen device using the Airplay device sound volume property.

UPDATE: Just to be clear, it is the main iTunes EQ setting that is changed, not the EQ setting for individual tracks.

More Airplay stuff

Earlier, I posted a way to hardcode the Airplay devices in a script. But if you only have one computer, AirPort Express, or Apple TV kind of Airplay device you can forego using the name property and do something like this, which sets my lone Apple TV as the current Airplay device:

tell application "iTunes"

set current AirPlay devices to (get AirPlay devices whose kind is Apple TV)

end tell

Even though there is only a single item result from Airplay devices whose kind is Apple TV, it's returned as a list which is what current AirPlay devices takes.

The other kind values, AirPlay device and unknown, are too generic to use this way—unless you know you only have one of them.

Hardcode Airplay Device Speakers

Correspondent Matt Stevens sent the following, which illustrates how to hard code your Airplay device names:

tell application "iTunes"

set computerSpeaker to (first AirPlay device whose name = "Computer")

set kitchenSpeaker to (first AirPlay device whose name = "Kitchen")

set current AirPlay devices to {computerSpeaker, kitchenSpeaker}

end tell

The current AirPlay devices application property accepts a list—even if the list is only one item.

Airplay device properties

These are the new Airplay device properties accessible via AppleScript:

active (boolean, r/o) : is the device currently being played to?
available (boolean, r/o) : is the device currently available?
kind (computer/AirPort Express/Apple TV/AirPlay device/unknown, r/o) : the kind of the device
network address (text, r/o) : the network (MAC) address of the device
protected (boolean, r/o) : is the device password- or passcode-protected?
selected (boolean) : is the device currently selected?
supports audio (boolean, r/o) : does the device support audio playback?
supports video (boolean, r/o) : does the device support video playback?
sound volume (integer) : the output volume for the device (0 = minimum, 100 = maximum)

Notice that all the properties are read-only (r/o) except for selected and sound volume, meaning only those two properties can be changed; the others can only be polled.

Basic Airplay script

This is a pretty basic use of the new Airplay stuff. Select and set your Airplay devices:

tell application "iTunes"

set apNames to (get name of AirPlay devices)

set apDevices to (get AirPlay devices)

set rez to choose from list apNames with prompt "Select Airplay:" with multiple selections allowed

if rez is false then return

set apPlays to {}

repeat with i from 1 to length of apNames

if item i of apNames is in rez then set end of apPlays to item i of apDevices

end repeat

set current AirPlay devices to apPlays

end tell
