Req: How to eliminate clicks/pops with Selector

[sunsynth]

I use Selectors for disable/enable Effects.

When i switch an Audio-Stream in action the selector produces distortions!

My 1st Idea is: bridge the selector and after timer-delay open the bridge...

The reason 4 this is - i don't want to mute a live signal!

Are there any other technics to avoid these artifacts? DC-Filter etc. ?

you could use the code component to build a smooth fade-in of the effect signal.

But there is a disadvantage: the effect section is always on, so it uses a lot of CPU power even if it is switched off.

This is something that bugged me in the past - ideally the devs could write a new selector for stream signals with a user-definable fade-out/fade-in time when switching between signals

I had a look into this, using a code component after the selector you can cause the new signal to fade in when the selector changes. That's pretty easy, the hard part is fading the old signal out. By definition when the signal path changes in the selector you no longer have access to the old signal so there's no simple way to fade it out! You need AFAIK both the old and new signals running at the same time in order to fade one out and the other in without clicks.

I've got an idea that uses two selectors both connected to the same streams. One selector routes the main stream, the other routes the previously chosen stream if that makes sense. Then you can fade between them easily. The downside is this requires two streams to be running continuously. Then again if you did it all in code you have all of the streams that would have been connected to the selector running so there's still the chance to reduce CPU if you have more than 2 streams connected to the selector!

Whew! Don't know if any of that makes sense, I'll try to build a schematic to do it - unless someone else has a more elegant solution

Thanks MyCo & Shifrin...

@MyCo: 1. i don't know how 2 code this, 2. i want 2 reduce cpu-use

@Shifrin: Yes - 2 me that makes sense!
Please try to build a schematic to do it

I'll give it a go, can't promise if/when I'll post anything though

Fine... I'll try it also, but with my little knowledge...

[Shifrin]

Just a little update, I've tried to do what I described but I still get clicks. So either there's some error with what I've done - or this is down to the selector switching not being sample-accurate - or maybe both - or something else entirely due to the nature of the relinking of code when using a selector

If I can't get it to work I'll post what I've done and maybe someone else can fix it - I know people have asked about this in the past but the fact I'm not aware anyone has posted a solution to this (including the devs) makes me think it might not be possible. Then again maybe someone's worked it out but wants to keep it private for commercial endeavours

Hmm...

I'm fiddeling with Triggers...Triggers...Triggers...
FlipFlop...timers...Sliders...Switches...Led's...Selectors...

i think i must not only write down some notes...
a Timesheet is needed 4 this more and more growing Project...

It's done: (1st Version)


and:


blender mono source: rl

i left the diagnose Led's just for fun!

Who has a better Name for this beauty? she don't like big Level dif.

After 6 days trial my 1st Module

P.S: Who want's .OSM? PM me... Say what...

Ooops i forget: YYEESS - this Beauty reduces the CPU Load!
