Robbert van der Helm c748d79963 Temporarily remove slew compensation 
We should probably just upsample the slews as a control signal and use
that instead.

Robbert van der Helm 4e0a0d4cd5 Move smoothing scratch buffers to the heap 
This is probably a good idea to keep the stack sizes small. A couple 32
element buffers should be fine, but these fit 512 elements each and
Windows can be fussy about stack sizes.

Robbert van der Helm d3f820dc8c Set the default oversampling amount to 2x 
Oversampling is not always needed, so this is probably a better default.

Robbert van der Helm 913aa4bef9 Decrease Soft Vacuum output gain range 
-40 dB sounds reasonable. No need to go down all the way to -100.0. The
original version was in the linear domain.

Robbert van der Helm 4b5f52252a Make the oversampling in Soft Vacuum configurable 2023-04-05 18:40:40 +02:00
Robbert van der Helm c6765d91ac Modify oversampler to allow variable no of stages 
This is needed to be able to add a control for the oversampler amount.
 2023-04-05 18:22:28 +02:00
Robbert van der Helm 40db21277e Fix debug assertions in oversampling 
These were leftover from before the addition of delays.
 2023-04-05 18:22:28 +02:00
Robbert van der Helm 1711efa11e Add a basic 4x oversampled version of Hard Vacuum 
The oversampling amount should be configurable, and it would work better
if the slew signal was oversampled independently instead of doing this
compensation thing.

Robbert van der Helm 8a7100ac3e Add an OversamplingAware smoothing style 
This can be used to have an ergonomic way to do multi-rate smoothing
with variable oversampling amounts that only the `Arc<AtomicF32>` to be
updated from a parameter callback.

Robbert van der Helm a8fa8cde66 Slowly fade in SC envelope followers 
This is much more gentle.

Robbert van der Helm 144fafbed6 Swap log2 in Spectral Compressor out for ln 
The ln() implementation is usually faster, and there's no reason to
prefer a specific base.
 2023-03-21 22:56:49 +01:00
Robbert van der Helm ab66152f00 Allow evaluate_plain() to be unused 
We won't need this, but it being there makes everything a lot clearer.
 2023-03-21 22:51:55 +01:00
Robbert van der Helm ea4dd8ead2 Move curve calculation to a dedicated struct 
So we can reuse this in the analyzer.

This looks a lot clearer.
 2023-03-21 17:57:26 +01:00
Robbert van der Helm a4cac4b750 Fix GR overlay clamping 
Just the min/max isn't enough when the entire band is out of range.
 2023-03-21 17:16:10 +01:00
Robbert van der Helm 9f5d1dcf57 Draw GR overlay as a single path with no AA

Robbert van der Helm 6e3d2379b0 Add a start of a gain reduction display 
This needs to be drawn as a single mesh instead, and it should also use
the target curve or it looks odd.
