Robbert van der Helm fdbff129f8 Use linear gain params in gain examples 
Using the new skewed coefficient calculation function for gain ranges
from a couple commits ago.

Closes #18.

Robbert van der Helm 44b9a4cad0 Add a way to compute skew factors for linear gain 
Needed for #18.

Robbert van der Helm 42c42dff9b Never compress the DC bin in SC 
This just results in more problems than it solves for small window
sizes.

Robbert van der Helm 6b26828839 Default both offsets to 0 dB again 
Otherwise the UI just looks weird.
 2022-07-24 19:01:28 +02:00
Robbert van der Helm 692b1051ad Avoid compressing DC bin on larger windows 
Even if the DC filter is disabled. We do want to compress this on
smaller windows as it covers the entire bass range.

Robbert van der Helm 2a464c478c Default SC global threshold to 0 dBFS 2022-07-24 18:30:20 +02:00
Robbert van der Helm ce0aa0079c Slightly lower the threshold parameter 2022-07-24 18:26:57 +02:00
Robbert van der Helm ce72dc5f03 Fix disabled DC filter behavior 
This fixes a NaN from taking the logarithm of zero, and the lower bins
are not actually compressed when this option is disabled. This is useful
when using tiny window sizes as the first bin will span quite a chunk of
the spectrum.

Robbert van der Helm 74b33af7d7 Fix DC bin skipping being off by one 2022-07-24 18:00:15 +02:00
Robbert van der Helm dffc169c99 Skew slope and curve more towards 0 
Especially positive curve values can get out of hand quick
 2022-07-24 17:48:02 +02:00
Robbert van der Helm d53d03c5cf Default downwards hi-freq rolloff to 0.25 
Sort of makes sense to have these two be symmetrical

Robbert van der Helm 22dcbdf4a9 Make the default parameters a bit more gentle 2022-07-24 17:25:58 +02:00
Robbert van der Helm c06b134e93 Show the upwards parameter on the left 
It makes more sense this way.
 2022-07-24 17:17:28 +02:00
Robbert van der Helm 126cf3b141 Add a disclaimer to the GUI 
Because there's a good chance things will change later and patches may
not sound exactly the same anymore.
 2022-07-24 17:13:09 +02:00
Robbert van der Helm 0b1d9b60db Also skew the slope parameter 2022-07-24 17:07:35 +02:00
Robbert van der Helm 3fe1769a43 Change the global threshold range 
This should go lower and it doesn't need to exceed much past 0
dBFS (since full 0 dBFS in the frequency domain will peak pretty hard in
the time domain).

Robbert van der Helm 455ab0364a Skew the threshold curve parameter 
Since the center values will be most interesting useful range.

Robbert van der Helm 7b02217ad4 Map from the Params object in GenericUi 
Otherwise reactivity doesn't work.

Robbert van der Helm 4f62ebd2ea Wrap nested Params structs in Arcs 
So we can use the generic UIs. Vizia needs these to be 'static.
 2022-07-24 15:15:47 +02:00
Robbert van der Helm 2fbf4ca00d Remove Copy requirement from Vizia generic UI 
This now uses a dummy lens to map to the parameter.
 2022-07-24 15:15:47 +02:00
Robbert van der Helm 4327828e6b Move the Params implementation to CompressorParams 
So now CompressorBankParams can just derive Params.
 2022-07-24 15:15:47 +02:00
Robbert van der Helm dc97fb1019 Implement Params for Arc<P: Params> 
This is useful for partial generic UIs.

Robbert van der Helm 278ae227a7 Make the Spectral Compressor editor a bit wider 
Next up is splitting this up in four generic UI panes to make it a bit
easier to use. That was why all of the previous commits moved parameters
around.

Robbert van der Helm 6ae1c55f76 Deduplicate compressors with custom Params impl 
This now also finally serves as an example on how to do this.

Robbert van der Helm 3c1a1c8f14 Move global parameters to their own struct 
We'll temporarily split the generic UI into four panes to make it a bit
easier to use.

Robbert van der Helm 06694683d3 Move the frequency center parameter down 
Somehow this is always where I'm looking for it.

The minus was missing here.
 2022-07-24 15:15:47 +02:00
Robbert van der Helm c2003879cb Store ratio reciprocals instead of ratios 
We're doing linear space compression, so we need the reciprocal of the
actual ratio.
