HISE Meet Up

[VirtualVirgin]

Something happened with the Jitsi meeting,
It stopped broadcasting the video conference and now it seems to think I'm the only one in the meeting.

Is the meeting still going on or did everyone get kicked out somehow?

[Chazrox]

Great meetup! Thank You @Christoph-Hart for everything & @d-healey for hosting!

I love the new visual profiler feature. I was literally doing this on paper the other day trying to figure out the flow of one of my scripts trying to figure out where its choking. This should help.

[d.healey]

@VirtualVirgin Yeah I got kicked into my own little personal chat at one point too and wondered where everyone had gone.

By the way, what you were saying about audio morphing, this is what I brought up many years ago and would still like to see. - https://forum.hise.audio/topic/188/smoother-dynamic-crossfades/6?_=1743624726883

Someone in the call mentioned using Loris for this and I said it can't be used in real-time, but actually now I think about it you might be able to use Loris if you did all the heavy lifting during development and then it just read from some kind of look-up table during realtime.

[HISEnberg]

@d-healey I somewhat take back what I said. I don't think you could do spectral morphing in realtime. Loris can definitely do spectral morphing and very well at that, but I think you would have to render your samples offline then bring those into HISE.

[HISEnberg]

Also great meeting and many applause to @Christoph-Hart for his work on the new sampler engine and profiling tools, both of which look extremely promising.

Eager to watch the meeting when avail.!

@d-healey Ah, apologies, I meant spectral morphing with Loris in HISE realtime, not realtime spectral morphing in general!

This plugin really caught my attention when it came out, though I am not sure it is completely spectral morphing or some other way of interpolating between samples:

Visco – Forever 89

Ah ok, yeah I think probably some form of look up table, perhaps generated by Loris, would be the most efficient way to go. Actually it's kind of like what we can do with the wavetable synth isn't it.

@ustk

It's been done in real time recently using loris.
But it's what David said: you need to make your own engine for playback, using Loris for analysis and creating your own optimized way of synthesising the result from the loris partials array.

Check out Sumu.
The synth does exactly that.
Mind though, that it uses 30% cpu per instance right off the bat...

@griffinboy said in HISE Meet Up:

Oh nice, they are using Loris and their analysis tool is open source.

[griffinboy]

@d-healey

This is what spurred me to make my own additive spectral in c++. I couldn't beat Lori's sound wise yet. But I did beat Sumu in terms of efficiency.

I wish we had efficient additive but I think we are a ways off from that lol. I can never bring myself to use plugins that use more than 10% CPU. I run out of CPu headroom too fast. It's a real shame. Because Sumu sounds awesome.

[d.healey]

Here's the recording from yesterday. We lost a couple of bits in the middle when the recording stopped and had to be restarted, we also lost about 10 minutes from the end because the audio cut out.

I think in future we should use zoom as the recording system is better. @Simon as you know I also prefer foss but since we're using a remote service with either jisti and zoom the openess of jitsi makes little difference - unless you're self hosting. I always use the browser version of zoom so no need to install anything or even make an account. However if you want to keep searching for another foss solution, or something self hosted I'm happy to give it a try too.

[Simon]

@d-healey My FOSSy convictions drive me to figure out the nextcloud recording backend, which is probably gonna be the most reliable zoom replacement. Sorry for the audio :)

[Oli Ullmann]

@d-healey Thank you! :-)

I find the Kyma to be rather convincing for smooth morphing:

I would love to hear this kind of thing used to interpolate between sample sets for articulations that have capabilities for continuous control of timbre:
bow position, fluttertongue, growl, stick position on percussion etc.

There are a few different algorithms to choose from for morphing on the Kyma, and I don't know the details, but I think these are precomputed FFTs for resynthesis.

[VirtualVirgin]

It looks like the Kyma may use Loris, or some aspect of Loris in its system.
Kyma is mentioned in both of these papers on Loris:

@d-healey sorry I couldn't make it in time to the meet, checking the youtube video now.
how did Kyma come into discussion? used this decades ago, didn't even know it still existed

We were discussing audio morphing/interpolation

[Morphoice]

@d-healey back in the days Kyma was the king of that, it's what they used for the podracers in Episode 1, I can't think of a better tool however back then you needed special hardware to use it
