### Additive Synthesis ### Additive Synthesis
To tame the harsh sound of the basic waveforms, we can set the `n` control to limit the overtones of the waveform: Periodic waveforms are composed of several [harmonics](https://en.wikipedia.org/wiki/Harmonic) above a fundamental frequency, lying at integer multiples. These overtones combine to give a sound its unique timbral quality.
For the basic waveforms, we offer you control over these harmonics with the `partials` and `phases` functions.
#### Partials
`partials` refers to the magnitude of each harmonic relative to the fundamental frequency. They can thus be used to spectrally filter these waveforms and tame some of their harshness:
<MiniRepl <MiniRepl
client:idle client:idle
tune={`note("c2 <eb2 <g2 g1>>".fast(2)) tune={`note("c2 <eb2 <g2 g1>>".fast(2))
.sound("sawtooth") .sound("sawtooth")
.n("<32 16 8 4>") .partials([1, 1, "<1 0>", "<1 0>", "<1 0>", "<1 0>", "<1 0>"])
._scope()`} ._scope()`}
/> />
When the `n` control is used on a basic waveform, it defines the number of harmonic partials the sound is getting. `partials` can also be used to construct _new_ waveforms not present in our basic set with the 'user' sound source:
You can also set `n` directly in mini notation with `sound`:
<MiniRepl <MiniRepl
client:idle client:idle
tune={`note("c2 <eb2 <g2 g1>>".fast(2)) tune={`note("c2 <eb2 <g2 g1>>".fast(2))
.sound("sawtooth:<32 16 8 4>") .sound("user")
.partials([1, 0, 0.3, 0, 0.1, 0, 0, 0.3])
._scope()`} ._scope()`}
/> />
Note for tidal users: `n` in tidal is synonymous to `note` for synths only. We may algorithmically construct lists of magnitudes with Javascript code like:
In strudel, this is not the case, where `n` will always change timbre, be it though different samples or different waveforms.
<MiniRepl
client:idle
tune={`const numHarmonics = 22;
note("c2 <eb2 <g2 g1>>".fast(2))
.sound("saw")
.partials(new Array(numHarmonics).fill(1))
._scope()`}
/>
which acts as a spectral filter. Or:
<MiniRepl
client:idle
tune={`note("c2 <eb2 <g2 g1>>").fast(2)
.sound("user")
.partials(new Array(50).fill(0)
.map((_, idx) => ((-1) ** (idx + 1)) / (idx + 1))
)
._scope()`}
/>
which recovers a familiar waveform.
`partials` is also compatible with pattern functions designed to produce lists, like `randL` or `binaryL`:
<MiniRepl
client:idle
tune={`note("c2 <eb2 <g2 g1>>").fast(2)
.sound("user")
.partials(randL(10))
._scope()`}
/>
and with lists _of_ patterns:
<MiniRepl
client:idle
tune={`note("c2 <eb2 <g2 g1>>".fast(4))
.sound("user")
.partials([1, 0, "0 1", "0 1 0.3", rand])
._scope()`}
/>
Note that the first value in the `partials` array controls the magnitude of the fundamental harmonic rather than the DC offset, which is fixed at 0.
#### Phases
Earlier, we mentioned that periodic waveforms can be broken into a set of harmonics above a fundamental frequency. Each harmonic has two defining properties: its magnitude (how loud it is) and its phase, which determines where in its cycle that sine wave starts when the waveform is built.
These phases too can be declared in Strudel and can give your sounds interesting depth.
<MiniRepl
client:idle
tune={`s("saw").seg(16).n(irand(12)).scale("F1:minor")
.penv(48).panchor(0).pdec(0.05)
.delay(0.25).room(0.25)
.compressor(-20).vib(0.3)
.partials(randL(200))
.phases(randL(200))`}
/>
