I am working on a drum trigger effect plugin that I want to use in a live setting, to enhance the kick drum by layering a sample on top of it.

I found this thread which talks about a particular snippet that can cause a drum recording to trigger a sine wave:

I want to change 2 things:

1. Instead of detecting audio from an audio loop player, I want to be able to detect incoming audio from the DAW (so that the plugin will be able to hear audio from the bass drum microphone).
2. Instead of triggering a sine wave, I want to trigger a kick drum one-shot. For now, I do not care about velocity settings or anything special like that.

I have been trying to tweak this snippet for hours, but I just don't have enough knowledge yet of the innerworkings of HISE to wrap my head around it. If anyone could point me in the right direction, I'd very much appreciate it!

Hello all,

I am attempting to build a drum trigger VST effect plugin inside HISE. As of now, I am using the file_player node and want to trigger it to only play when incoming audio exceeds a certain threshold. I originally thought to use a dynamics.envelope_follower to analyze the incoming signal and then use it to modulate the file_player's "gate" parameter, but this doesn't work as intended.

Any suggestions for how to trigger the file_player only when incoming audio reaches the threshold?

I want to create a plugin that eliminates feedback for live vocal microphones (plugin will be used in a live setting).

This would be a "last line of defense", to be used after ringing out the PA system and using traditional feedback reduction methods. I came across the following snippet, which analyzes the incoming audio and spits out the loudest frequency:

Perhaps we can then attenuate that frequency? -- although I predict there would be issues with using this method (how would we prevent reducing the fundamental freq. of the vocal?)

And I assume that the processing needed to make this work could also lead us to potentially creating a "Soothe" clone in HISE as well (FFT based processing, reducing resonant frequencies)

Any other thoughts?

@ustk thank you, your suggestion of using the Math.mul node seems to work best for what I'm trying to achieve.

The dynamic range of 32 bit audio is 1528 dB. Perhaps setting the gain node to something -1600 (just to be safe) may work, but that seems a bit clunky for me. Weird things happening with the analyzer when I do it.

Would there be a way for me to create a UI slider on my plugin, where dragging it all the way down will make the audio silent, and dragging it up would increase the gain (just like a fader on a console or in a DAW)? Would I have to code something where, if the slider is in the lowest possible position, the Math.mul node becomes engaged? Or, maybe I should start using Math.mul nodes instead of Core.gain.

Thanks all for looking into this and for your help!

@d-healey in a perfect world I would want to set gain to -inf, so that placing any increment of gain (such as +100, even +1000) will not let us hear any signal at all. I will test it, but based on floating point theory the user should indeed be able to hear the unwanted signal in the DAW if they turn it up.

If it's not possible to set the min value on a gain node to silence, is there another way to achieve this using scriptnode?

@d-healey that's originally what I had assumed, but then I noticed that if you put a -100 gain node, followed by a +100 gain node, you end up still having signal. I assume this is because of 32 bit floating point. My concern is that the end user of the plugin in their DAW can end up raising the -100 dB signal as well since their DAW would be in 32 bit floating point also.

Hi, sorry for the stupid question, I just started using HISE recently. I want to use a gain node but how can I make the range of the knob go from silence to 0 dB? When I try to set minimum knob value to "-inf" HISE crashes.

@aaronventure that's great news. Just went through the whole thread -- I wonder if it would be possible to get this set up in HISE now, especially after the recent updates from Jatin. @Christoph-Hart would this be simple enough to add to HISE with Jatin's contributions? If not, would anyone be able to point me in the right direction as to next steps to get NAM distortion profiles up and running in HISE? Thank you!!

I am working on a guitar amp modeling plugin (distortion profile + impulse response) and came across Neural Amp Modeler, which is open-source. I am wondering if I could integrate the code from Neural Amp Modeler into HISE, and if so, how? I apologize for my lack of understanding when it comes to scripting and navigating github/other resources, I started very recently and still trying to grapple with the basics.

I just need the distortion profile from NAM, not the profile switcher or IR loader. I believe I can use the built in HISE convolution tool to load impulse responses. Would it be possible to hardcode a specific .nam profile into a HISE plugin? Thank you all for your help!
