How do I fade every audio file that is currently playing?

Question

Hello!

First of all: I use the current version of Twine (2.2.1) and SugarCube 2. And I've read the audio macro list, but I still don't understand how to do that.

What I want is to fade out whichever audio file is currently playing while starting to play a new one. A simple transition, basically. But apparently you can't use "fadeout" for whole audio groups, just for playlists. So what I tried is creating a playlist with every audio file in it (in StoryInit as recommended) and then say in the passage: <<playlist "AllCachedAudioFiles" fadeout>> <<audio "NewAudioFile" play loop>>

It doesn't work, it doesn't fade out. Could it be that it doesn't work because "NewAudioFile" is also within the "AllCachedAudioFiles" playlist?

I'm unsure how you got that the fadeout action was only usable with playlists.  The <<audio>> macro documentation clearly lists it as an available action.

Regardless.  To fade out all currently playing audio, which hasn't been copied into a playlist, and also start a new track playing looped, you want something like the following:

<<audio ":playing" fadeout>><<audio "track that is not playing" loop play>>

 

Also.  Do not confuse playlists, created with the <<createplaylist>> macro, with either the built-in groups or custom groups, created with the <<createaudiogroup>> macro.  A playlist is a queue of tracks to play in some sequence, controlled via the <<playlist>> macro.  A group is simply a list of tracks which allow you to issue commands to multiple tracks simultaneously, controlled via the <<audio>> macro.
