AudioDSP Add-On Chains

[AchimTuran]

Detailed Description

Within this issue the AudioDSP processing chain will be reactivated to allow multiple algorithms to be processed in series.

Context

Your setup might require a complex processing chain and you would like to use an equalizer, dowmixers ... at the same time to tweak your sound like you want.

Possible Implementation

I'm pretty sure a lot of code from the past can be reused to achieve the goal of this issue. Furthermore it is damn pretty cool if you can setup a processing chain with your personal preferences.

I do have something similar in mind, which I wrote back in the past in this forum thread.
