In current the sub is actually an additive synthesis engine.fmr wrote: Mon Oct 16, 2023 11:16 amNeither do you see anything like that in Current, AFAIK. You need a very powerful and extensive Additive Synthesis Engine to do that.kraster wrote: Mon Oct 16, 2023 10:54 amYeah.Jac459 wrote: Mon Oct 16, 2023 10:28 am
Spent 15 minutes, can't see anything related to spectral synthesis.
I generally think of spectral resynthesis when someone mentions spectral.
Spectral resynthesis is usually analysis of the spectral content using FFT and then resynthesised using partials and residuals (filtered noise). As you said above the most common form of reconstruction is using additive synthesis.
I don't see anything like that in Skydust. It's a subtractive/FM hybrid with some fancy sound field capabilities (depending on the version)
Alchemy is a good example of a synthesizer capable of Resynthesis, due to its powerful additive synthesis engine (that's its original synthesis engine). Some wavetable synthesizers also perform a kind of resynthesis (again, when their wavetable is additive based as was the case of the PPG/Waldorf. Tone 2 Icarus is a good example of a synthesizer that performs sample analysis and wavetable creation with very good quality. Serum also performs resynthesis through wavetable creation, as do Pigments, and almost all of the wavetable synthesizers. But I personally don't classify that as spectral synthesis.You can do instantaneous spectral analysis in Msoundfactory with the additive oscillator and modal filter. But it's not dynamic.
Alchemy has a pretty good spectral engine.
I think the upcoming Sumu by Madrona labs (if it ever sees the light of day) looks like it will be the big Kahuna of spectral synths.
Arturia Fairlight and Synclavier both perform resynthesis as well (these in a more traditional analysis and resynthesis through additive way). Virsyn Cube (unfortunaley now abandonware) was perhaps the most powerful analysis and resynthesis synth I ever knew. That's what I would classify as a fully featured spectral synth: https://www.virsyn.net/desktop/cube.html
Regarding SkyDust, it has Oscillator Modifiers, which alter the waveform spectrum and work in real-time. That's what brings SlyDust close to Current, IMO. Here's a description:
"Waveform modifiers, also known as waveform shaping, are techniques and tools that enable you to modify the shape and characteristics of a waveform generated by an oscillator. These modifiers provide the means to sculpt and manipulate the timbre of the waveform, allowing you to create complex and distinctive sounds that go beyond the standard waveforms. Within SkyDust, you have access to a variety of modifiers that greatly enhance your ability to manipulate and shape sounds. These modifiers include Silence, Amplitude Offset, Wave Folding, Positive Wave Folding, Clipping, Bit Crusher, Time Shift Up, and Time Shift Down. By utilizing these modifiers, you can expand your creative possibilities and explore new dimensions in sound manipulation."
The modifiers of SkyDust are NOT spectral. The wace shaping is immediately applied to the wave.
In Thorn, Europa or Current, the wave is first decomposed in partials sin waves and then processed. The difference for the user is much more flexibility of processing.
