Robbert van der Helm 1424b98e38 Break PolyModulation into that and MonoAutomation 
This is needed to properly support polyphonic modulation, since the
modulated value may still be automated in the meantime and the
polyphonic modulation must act as an offset for that value. This does
mean that the plugin must add the normalized value and normaliezd offset
by itself. The `PolyModulation` event now also contains a description of
how this can be used. It would have been nicer to be able to send
polyphonic automation-style events instead (like the PolyModulation was
doing before), but that's sadly not feasible without NIH-plug being
involved in the voice management.

Robbert van der Helm e8764e7327 Use double precision for exponential step sizes 
Otherwise you will get issues with rounding errors if someone ever tries
to have smoothing times over a second or so.

Robbert van der Helm 1fea9f94df Deduplicate the smoother implementation 
By introducing a new trait for conversion to and from floating point
numbers.

Robbert van der Helm dc5dfb06c6 Reach 99.99% of target for exponential smoothing 
Instead of 99.97%. Both numbers are not based on anything, but this
calculation makes more sense.

Robbert van der Helm 28c7ea4843 Rename ExponentialIIR -> Exponential 
The suffix was added to denote that this could do some funny things
because of the snapping to the target value, but in practice that
snapping distance will likely be so tiny that it is likely not
noticeable.

Robbert van der Helm 116d245149 Add an exponential smoothing style 
Based on a one-pole IIR low pass filter that reaches 99.97% of the
target value in the designated time before snapping to that value. This
will be less efficient than the linear FIR smoothing style.

Apparently it showed this text verbatim, and not in monospace.

Robbert van der Helm 3122c0cb41 Pass block references to the block smoother 
So you can't mess this up by passing the maximum block size instead.

Robbert van der Helm fd3f4c2c48 Allow skipping steps in the smoothers 
I'll need this for Diopser since it's going to have a parameter to
control the automation's granularity.

Robbert van der Helm 2486368d08 Use AtomicF32 for the smoothing 
This should at least not have a big performance impact since we can use
relaxed memory ordering here. AtomicCell always uses acquire/release
ordering.
 2022-02-06 03:43:59 +01:00
Robbert van der Helm bf070fce5a Use atomics in the smoother 
This is needed so we can share the params with the editor, but it isn't
great, is there a better alternative?

Robbert van der Helm 073fe743c2 Split up set_target and reset in smoothers 
This makes it a bit less awkward to use in user code, if you need a
separate smoother there.
