Cut sound when music is too loud

[lenskaraoke]

Is it possible (Or does anyone know of a script that already does this) to write a script where the sound can be cut completely when music is played too loud. I want it to work regardless of the app that’s playing the music, in other words I want the computer volume to be turned off so the user has to manually turn it back to an acceptable level where the sound isn’t getting turned off. The music is played through an external amp.

Hi lenskaraoke,

There is the StandardAdditions osax that allows you to get and set the sound volume. Here’s the dictionary part:

get volume settings‚v : Get the sound output and input volume settings
get volume settings
→ volume settings : a record containing the sound output and input volume settings
see also
set volume.
volume settings‚n : Reply record for the ˜get volume settings’ command
properties
output volume (integer, r/o) : the sound output volume
input volume (integer, r/o) : the sound input volume
alert volume (integer, r/o) : the alert volume (as a percentage of the output volume)
output muted (boolean, r/o) : Is the sound output muted?
set volume‚v : Set the sound output and/or input volume
set volume [number] : the sound output volume, a real number from 0 to 7 (This parameter is deprecated; if specified, all other parameters will be ignored.)
[output volume integer] : the sound output volume, an integer from 0 to 100
[input volume integer] : the sound input volume, an integer from 0 to 100
[alert volume integer] : the alert volume, an integer from 0 to 100
[output muted boolean] : Should the sound output be muted?

get volume settings.

It’s pretty straight forward. First get the sound volume. Then, if it is too loud then set it to zero. It can get more complicated.
