Invert polarity of sampler

Is there any way to invert the polarity of audio in a sampler? AKA phase filp? I don't see a button on the sampler or any FX.

I think I'll add this to the SimpleGain module, but you can already do that with a scripted FX:

This patch contains two sine generators and a scripted FX that flips the phase of one of them (resulting in silence). It's not super efficient but it should work for now.

@christophhart thanks! Ill check that out

@ChristophHart found this old post (@Jay remembered it)
What's the range for those values. +1 to 1 ? Or it's in radiants?
Im trying to add phase value to my sinewaves generators
Also can this be used as phase shift?

No a phase inverter simply multiplies the signal with 1 so you can get only 180 degrees or nothing.
I suggest you play with the start offset parameter in your event processing, with a little bit of math you should be able to make sample perfect phase adjustments for every synthesised waveform in HISE

@ChristophHart Thanks!!! was trying to do it with Delay in SimpleGain FX.
Start offset should be calculated for every note then? due offset will be different for every frequency (note) right? or there's a simple way to do it?

Yes, but you just feed the frequency into your formula and it spits out a sample value that you need. Iβll write a example when I get back in a few hours.

@ChristophHart AWESOME!!!!! I'll be picking frequencies from a pitch table with some breakpoints, Can you do your example using this snippet? Otherwise I will figure it out later

This is the most boring example you'll ever get  if it works correctly, you should hear nothing, because the two sine waves cancel each other out
The interesting part is this script:
const var phase = Content.addKnob("Phase", 0, 0); phase.setRange(0, 360, 0.1); phase.set("suffix", "Β°"); function onNoteOn() { local offset = phase.getValue() / 360 * 2048; Message.setStartOffset(parseInt(offset)); } function onNoteOff() { } function onController() { } function onTimer() { } function onControl(number, value) { }
Just drop it on every sine generator where you want to adjust the phase and set the phase knob to your likings (you might run into performance issues if you use 100 of these modules though).
The formula is even easier than I thought  the reason is that the sine wave generator internally uses a look up table with linear interpolation and a fixed "wavetable" size of 2048, so you even don't need the exact frequency for it.

@ChristophHart AWESOME!!!!!!!!!!!!!!!
Will be awake all the night I guess!!!!

@ChristophHart works absolutely fine!!!!. You just made the perfect additive synth
A question: This script takes sine frequency after or before a pitch modulator? I do use pitch tables on every sinewave module

@hisefilo ok now you are going to have to define how I might make an additive synth using this...

Same, I don't understand where you need this in additive synthesis?

@Lindon LOL nah is just a part of it. You need to add a bunch of sinewaves by yourself. But now with this you can control phase on those sinewaves adding this script to each one of them

@ustk AFAIK additive synthesis is the summation of pure sinewaves. Displacing them over Y axis (phase) will affect the generated waveform. I use it to get timbres cannot be done without displacing phase (phase shift). To be honest don't know if it's a feature a real additive synth comes with

@hisefilo I got it
A real synth is a synth you make

The phase is independant from the frequency because they all use the fixed wavetable length of 2048 samples.
But to be honest the experiments I made with additive synthesis lead me to discard any efforts of reproducing the phase of harmonics because you simply donβt hear it  but I am curious about your findings

@ChristophHart I can hear the difference, but is much more obvious looking at the waveform. These are the 16 same sinewaves played together.
No phase:
Phase shifted:
I guess nature planed the waveform to look like last one

Yes, that the waveforms look different is obvious, but as far as I know, human ears have a very hard time to distinguish phases between harmonics.
