Robbert van der Helm 3d6cad54dd Reset SC envelopes to sqrt(1/2) to prevent pops 2022-07-26 18:51:27 +02:00

 2022-07-25 16:47:42 +02:00
Robbert van der Helm 6da8756e31 Use unchecked access instead of zip 2022-07-25 16:33:24 +02:00

Using the new skewed coefficient calculation function for gain ranges
from a couple commits ago.

Closes #18.
 2022-07-24 21:21:13 +02:00
Robbert van der Helm 7b66145e8b Use correct gain skew factor for Safety Limiter 2022-07-24 20:48:13 +02:00
Robbert van der Helm e20b10d601 Store SC output gain as linear gain 
Using the new conversion function.
 2022-07-24 20:46:49 +02:00
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.
 2022-07-24 19:04:53 +02:00
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.
 2022-07-24 18:39:04 +02:00
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.
 2022-07-24 18:25:46 +02:00
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
 2022-07-24 17:43:31 +02:00
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).
 2022-07-24 17:06:20 +02:00
Robbert van der Helm 4a2373b664 Implement upwards compression 2022-07-24 16:56:01 +02:00
Robbert van der Helm 8ca66cf9bb Move the main threshold up in the list 2022-07-24 16:29:50 +02:00
Robbert van der Helm 455ab0364a Skew the threshold curve parameter 
Since the center values will be most interesting useful range.
 2022-07-24 16:24:31 +02:00
Robbert van der Helm 068549607d Add soft-knee downwards compression 2022-07-24 15:58:30 +02:00

Robbert van der Helm b3166e3977 Rearrange Spectral Compressor GUI into 4x4 grid 2022-07-24 15:15:47 +02:00
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 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 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.
 2022-07-24 15:15:47 +02:00
Robbert van der Helm 6ae1c55f76 Deduplicate compressors with custom Params impl 
This now also finally serves as an example on how to do this.
 2022-07-24 15:15:47 +02:00
Robbert van der Helm fa392e61f1 Move attack and release to global parameters 2022-07-24 15:15:47 +02:00
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.
 2022-07-24 15:15:47 +02:00
Robbert van der Helm c53726bf9e Move the global threshold down in the list 2022-07-24 15:15:47 +02:00
Robbert van der Helm 06694683d3 Move the frequency center parameter down 
Somehow this is always where I'm looking for it.
 2022-07-24 15:15:47 +02:00
Robbert van der Helm 7db5da7930 Make the slope parameter range wider 2022-07-24 15:15:47 +02:00

Robbert van der Helm eda842c6a9 Fix the envelope coefficients 
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.
 2022-07-24 15:15:47 +02:00
Robbert van der Helm ef3a7a76d5 Handle 0 attack and release 2022-07-24 15:15:47 +02:00
Robbert van der Helm dae9dc758c Implement the envelope followers 2022-07-24 15:15:47 +02:00

Robbert van der Helm e68bb8d632 Add a stub for a compressor bank 
This is what the compressor data structure will more or less look like.
The thresholds and ratios still need to be split up in their upwards and
downwards counterparts and the callback listeners should be updated
accordingly.
 2022-07-24 15:15:47 +02:00
Robbert van der Helm fdcf8f79bc Make the Spectral Compressor editor taller 
All the sliders.

This makes them too long otherwise.

Robbert van der Helm 6e89d3737b Change the scaling on Safety Limiter's threshold 
With the addition of negative values the linear scale doesn't work
anymore.
 2022-07-22 22:49:59 +02:00

Robbert van der Helm ba7b5a3b32 Fix examples for out of order events 
This would be a host bug, but in theory CLAP hosts could provide out of
order events this way.

Robbert van der Helm 097d6c9fc4 Terminate all matches voices in PolyModSynth 
This is needed for a single NoteOff followed by multiple NoteOns for the
same key/channel with different note IDs.

Robbert van der Helm c36f29e3ca Add basic voice management for PolyModSynth 
This of course still misses important things like amplitude envelopes,
so notes will never end on their own. Those will be added as part of
audio processing.
