Robbert van der Helm d42fd41007 Buffers for zero channel plugins are always valid 2022-05-22 22:48:55 +02:00
Robbert van der Helm 937842d2c5 Suggest copying {Bus,Buffer}Config as needed 2022-05-22 13:39:19 +02:00
Robbert van der Helm 783dc2245e Store the processing mode in BufferConfig 
Instead of having a function on ProcessContext.
 2022-05-22 13:33:38 +02:00
Robbert van der Helm ee3b0bf8e6 Store the minimum buffer size in BufferConfig 2022-05-22 13:21:39 +02:00
Robbert van der Helm e1d4be2a03 Change NON_AUTOMATABLE semantics and add HIDDEN 
This now lets you have parameters that cannot be automated but that are
still changeable through the generic UI.
 2022-05-22 12:37:30 +02:00
Robbert van der Helm 985db44503 Allow marking CLAP plugins as hard realtime 2022-05-22 01:01:59 +02:00
Robbert van der Helm 2ac013df64 Fix warnings 2022-05-22 00:59:04 +02:00
Robbert van der Helm 665108721a Add a way to fetch the current processing mode 2022-05-22 00:58:53 +02:00
Robbert van der Helm 9601c9c0c1 Fix modulating non-smoothed parameters 
And also get rid of duplicate code here.
 2022-05-20 16:12:48 +02:00
Robbert van der Helm 4587c1405f Move VST3 buffer initialization 
This was left over from the last commit.
 2022-05-18 19:41:43 +02:00
Robbert van der Helm 024307872a Move VST3 initialization to set_active() 
Because the host may still change the channel layouts at this point.
 2022-05-18 19:29:48 +02:00
Robbert van der Helm 8239169aaf Add some pointers for getting started to the docs 2022-05-13 15:08:05 +02:00
Robbert van der Helm 6fc0b2e148 Call Plugin::initialize() for runtime preset load 
It's the plugin's responsibility to not do any realtime unsafe work here
if they support runtime preset loading.
 2022-05-13 14:46:25 +02:00
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.
 2022-05-12 13:50:45 +02:00
Robbert van der Helm 6a40cc9916 Remove debug print 2022-05-12 13:44:22 +02:00
Robbert van der Helm f3d02f6210 Fix updated exponential smoothing 2022-05-12 13:44:01 +02:00
Robbert van der Helm 1fea9f94df Deduplicate the smoother implementation 
By introducing a new trait for conversion to and from floating point
numbers.
 2022-05-12 13:34:02 +02:00
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.
 2022-05-12 13:21:32 +02:00
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.
 2022-05-12 02:22:12 +02:00
Robbert van der Helm 222036b335 Get rid of unnecessary loop in ExponentialIIR 2022-05-12 01:56:16 +02:00
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.
 2022-05-12 01:35:01 +02:00
Robbert van der Helm 0355ed3168 Add flush-to-zero support for AArch64 2022-05-10 23:12:52 +02:00
Robbert van der Helm c141314e30 Update for CLAP 0.25 2022-05-09 16:50:24 +02:00
Robbert van der Helm 55eeb689dd Add a padding option to StftHelper 2022-05-08 02:12:37 +02:00
Robbert van der Helm d0fcc9878e Add a Blackman window function 2022-05-08 00:47:20 +02:00
Robbert van der Helm 77b9dd3404 Reuse hann_in_place() for hann() window function 2022-05-08 00:31:55 +02:00
Robbert van der Helm ffe4642aa5 Implement IProcessContextRequirements 
This is needed for VST 3.7. We claim to be a VST 3.6.14 plugin, but
implementing this anyways seems like the safe bet. I doubt many hosts
would, but under VST 3.7 hosts are allowed to not send any transport
information unless this interface is implemented.
 2022-05-07 13:24:17 +02:00
Robbert van der Helm f05e31d9e3 Sort additional VST3 interace implementations 
The sensible order would be IComponent, IEditController,
IAudioProcessor, and then everything else.
 2022-05-07 13:18:20 +02:00
Robbert van der Helm a74d8264fb Support CLAP transport information events 
This will cause the buffer to be split when the transport information
changes.
 2022-05-05 17:23:46 +02:00
Robbert van der Helm 7cb671319e Properly define all predefined note expressions 
This is apparently how you're supposed to do it in VST3. How would you
know? You'd ask Steinberg.
 2022-05-05 15:35:14 +02:00
Robbert van der Helm 06c5e4b04a Make parameter modulation stick after automation 
This is how it's supposed to be implemented in CLAP.
 2022-05-02 15:46:57 +02:00
Robbert van der Helm 10ae8e1d05 Enable modulation for CLAP parameters 
Everything else has already been implemented, but this is kind of
important.
 2022-05-02 11:51:56 +02:00
Robbert van der Helm a4b251e5ef Support monophonic modulation for CLAP plugins 
This avoids the potential for state corruption caused by modulation and
modulation can be displayed differently on the GUI.
 2022-05-01 19:05:51 +02:00
Robbert van der Helm ddbaffc0bb Add ParamMut method for setting modulation offset 
This will be used in the CLAP wrapper to handle `CLAP_EVENT_PARAM_MOD`.
 2022-05-01 19:03:04 +02:00
Robbert van der Helm 1d3ac1b2af Move param setting functions to new ParamMut trait 
This makes things slightly less confusing because these functions should
never be called from user code.
 2022-05-01 18:45:35 +02:00
Robbert van der Helm a17c63bf71 Add parameter getters for unmodulated values 
This is needed to be able to support modulation events in CLAP. There an
offset gets applied to the parameter's actual current value. That way
GUIs don't have to move around when parameters are being modulated and
save states cannot get influenced by modulation.
 2022-05-01 18:30:30 +02:00
Robbert van der Helm 6451555f85 Add missing #[inline] attribute 2022-05-01 17:56:20 +02:00
Robbert van der Helm 2026257561 Get rid of Default implementations on ranges 
These also don't make any sense anymore and will likely lead to more
problems than they solve.
 2022-05-01 17:40:53 +02:00
Robbert van der Helm d6bdfd7391 Get rid of Default implementations for params 
These don't make any sense anymore with the builder API.
 2022-05-01 17:40:26 +02:00
Robbert van der Helm cd628e80ee Store normalized values on the param structs 
This will be necessary to implement CLAP modulation later.
 2022-05-01 17:34:59 +02:00
Robbert van der Helm 54d2a4cd2c Hide param fields other than value and smoothed 
Direct initialization was no longer recommended anyways since now you
need to keep the default value in sync. The next couple of commits will
add a normalized value field and two more fields to help with
modulation.
 2022-05-01 17:08:08 +02:00
Robbert van der Helm 40b555bfbd Document how values work in the Param trait 2022-05-01 16:40:18 +02:00
Robbert van der Helm 48d0f87e4c Mark param value getters as inline 2022-05-01 16:40:16 +02:00
Robbert van der Helm 98876670f8 Re-export debug macros from the debug module 
This makes it easy to import just the macros without having to use the
oldschool `#[macro_use] extern crate ...;` syntax.
 2022-04-30 02:10:54 +02:00
Robbert van der Helm 3d454bfc9c Don't process audio at all with invalid buffers 
If the host does some kind of flush this way with num_samples > 0 but
without any outputs or with zero output channels then we should not try
to read from the now invalid pointers from the previous cycle.
 2022-04-30 02:00:09 +02:00
Robbert van der Helm ddc28eef5e Clarify the VST3 output .take(num_outputs) 2022-04-30 01:52:53 +02:00
Robbert van der Helm e35886c216 Move window function handling out of StftHelper 
And apply the window function only once at the end of the process
function for the plugins that used it.
 2022-04-28 17:20:39 +02:00
Robbert van der Helm 4fb67a720b Add a todo for fallback DPI scale detection 2022-04-27 19:26:39 +02:00
Robbert van der Helm b89b4dfbb2 Add a .previous_value() method to the smoothers 2022-04-27 17:43:40 +02:00
Robbert van der Helm 6185909ddf Also safeguard against zero channel counts in CLAP 2022-04-27 17:06:19 +02:00
