You need an Extension Manager to install 3rd party add-ons. Try this one from Anastasiy.
Unfortunately, we can't help you with support for 3rd party widgets. Also Muse is discontinued. Use at your own risk.
Which Audio Trigger widget did you buy? If one did sell you a muse widget that ends with a .zxp it might be wrong. The only advice I can give from far away - talk to the vendors of this widget. Is it a widget inside a theme/template you purchased?
As Muse is under EOL it is very difficult to get reliable widgets, simply because most vendors were made to change the horse, if you know what I mean. From my own experience I know only muse-themes.com, but only because I almost never used other vendors (musegrid.com has moved over a year ago) and also because I tried to avoid 3rd party widgets as much as possible.
One final advice, although Muse will work for quite a long time - try to change as soon as possible, means, be aware that OS (like windows 10 for example) or browsers might change their settings quit unexpectedly and at a time when you with Muse probably can´t cope with it.
