286e62adf5 Simplify sample frame operations (make it a class) (#7156)
* Remove the struct StereoSample

Remove the struct `StereoSample`. Let `AudioEngine::getPeakValues` return a `sampleFrame` instead.

Adjust the calls in `Mixer`  and `Oscilloscope`.

* Simplify AudioEngine::getPeakValues

* Remove surroundSampleFrame

Some code assumes that `surroundSampleFrame` is interchangeable with `sampleFrame`. Thus, if the line `#define LMMS_DISABLE_SURROUND` is commented out in `lmms_basics.h` then the code does not compile anymore because `surroundSampleFrame` now is defined to be an array with four values instead of two. There also does not seem to be any support for surround sound (four channels instead of two) in the application. The faders and mixers do not seem to support more that two channels and the instruments and effects all expect a `sampleFrame`, i.e. stereo channels. It therefore makes sense to remove the "feature" because it also hinders the improvement of `sampleFrame`, e.g. by making it a class with some convenience methods that act on `sampleFrame` instances.

All occurrences of `surroundSampleFrame` are replaced with `sampleFrame`.

The version of `BufferManager::clear` that takes a `surroundSampleFrame` is removed completely.

The define `SURROUND_CHANNELS` is removed. All its occurrences are replaced with `DEFAULT_CHANNELS`.

Most of the audio devices classes, i.e. classes that inherit from `AudioDevice`, now clamp the configuration parameter between two values of `DEFAULT_CHANNELS`. This can be improved/streamlined later.

`BYTES_PER_SURROUND_FRAME` has been removed as it was not used anywhere anyway.

* Make sampleFrame a class

Make `sampleFrame` a class with several convenience methods. As a first step and demonstration adjust the follow methods to make use of the new functionality:
* `AudioEngine::getPeakValues`: Much more concise now.
* `lmms::MixHelpers::sanitize`: Better structure, better readable, less dereferencing and juggling with indices.
* `AddOp`, `AddMultipliedOp`, `multiply`: Make use of operators. Might become superfluous in the future.

* More operators and methods for sampleFrame

Add some more operators and methods to `sampleFrame`:
* Constructor which initializes both channels from a single sample value
* Assignment operator from a single sample value
* Addition/multiplication operators
* Scalar product

Adjust some more plugins to the new functionality of `sampleFrame`.

* Adjust DelayEffect to methods in sampleFrame

* Use composition instead of inheritance

Using inheritance was the quickest way to enable adding methods to `sampleFrame` without having to reimpement much of `std::array`s interface.

This is changed with this commit. The array is now a member of `sampleFrame` and the interface is extended with the necessary methods `data` and the index operator.

An `average` method was added so that no iterators need to be implemented (see changes in `SampleWaveform.cpp`).

* Apply suggestions from code review

* Fix warnings: zeroing non-trivial type

Fix several warnings of the following form:

Warnung: »void* memset(void*, int, size_t)« Säubern eines Objekts von nichttrivialem Typ »class lmms::sampleFrame«; use assignment or value-initialization instead [-Wclass-memaccess]

* Remove unnecessary reinterpret_casts

Remove some unnecessary reinterpret_casts with regards to `sampleFrame` buffers.

`PlayHandle::m_playHandleBuffer` already is a `sampleFrame*` and does not need a reinterpret_cast anymore.

In `LadspaEffect::processAudioBuffer` the `QVarLengthArray` is now directly initialized as an array of `sampleFrame` instances.

I guess in both places the `sampleFrame` previously was a `surroundSampleFrame` which has been removed.

* Clean up zeroSampleFrames code

* Fix warnings in RemotePlugin

Fix some warnings related to calls to `memcpy` in conjunction with`sampleFrame` which is now a class.

Add the helper functions `copyToSampleFrames` and `copyFromSampleFrames` and use them. The first function copies data from a `float` buffer into a `sampleFrame` buffer and the second copies vice versa.

* Rename "sampleFrame" to "SampleFrame"

Uppercase the name of `sampleFrame` so that it uses UpperCamelCase convention.

* Move SampleFrame into its own file

Move the class `SampleFrame` into its own class and remove it from `lmms_basics.h`.

Add forward includes to all headers where possible or include the `SampleFrame` header if it's not just referenced but used.

Add include to all cpp files where necessary.

It's a bit surprising that the `SampleFrame` header does not need to be included much more often in the implementation/cpp files. This is an indicator that it seems to be included via an include chain that at one point includes one of the headers where an include instead of a forward declaration had to be added in this commit.

* Return reference for += and *=

Return a reference for the compound assignment operators `+=` and `-=`.

* Explicit float constructor

Make the  constructor that takes a `float` explicit.

Remove the assignment operator that takes a `float`. Clients must use the
explicit `float` constructor and assign the result.

Adjust the code in "BitInvader" accordingly.

* Use std::fill in zeroSampleFrames

* Use zeroSampleFrames in sanitize

* Replace max with absMax

Replace `SampleFrame::max` with `SampleFrame::absMax`.

Use `absMax` in `DelayEffect::processAudioBuffer`. This should also fix
a buggy implementation of the peak computation.

Add the function `getAbsPeakValues`. It  computes the absolute peak
values for a buffer.

Remove `AudioEngine::getPeakValues`. It's not really the business of the
audio engine. Let `Mixer` and `Oscilloscope` use `getAbsPeakValues`.

* Replace scalarProduct

Replace the rather mathematical method `scalarProduct` with
`sumOfSquaredAmplitudes`. It was always called on itself anyway.

* Remove comment/TODO

* Simplify sanitize

Simplify the `sanitize` function by getting rid of the `bool found` and
by zeroing the buffer as soon as a problem is found.

* Put pointer symbols next to type

* Code review adjustments

* Remove "#pragme once"
* Adjust name of include guard
* Remove superfluous includes (leftovers from previous code changes)

9b6e33aa5c Remove global oversampling (#7228)
Oversampling can have many different effects to the audio signal such as latency, phase issues, clipping, smearing, etc, so this should really be an option on a per-plugin basis, not globally across all of LMMS (which, in some places, shouldn't really need to oversample at all but were oversampled anyways).

9bdc8adf33 Inform effects about changes in enabled model (#7237)
Add the virtual method `Effect::onEnabledChanged` which can be overridden by effects so that they can react to state changes with regards to being enabled or bypassed. The call of this methods is connected to state changes of the enabled model in the constructor of `Effect`.

Implement the method in `DualFilterEffect` by resetting the history of the two filters. This is done to prevent pops that have been reported in #4612.

a1b355828e Allow sub plugins for instruments aswell
* Move m_key member of Effect into Plugin
* Pass key to Instrument ctors and instantiaters
* Add pluginKeys to all plugin selector widgets, and let them pass the keys
  when instantiating the instruments; or, if the keys must be passed over
  threads, pass the keys to the Engine using `Engine::setDndPluginKey()`
* As instrument plugin libraries now also need to get their key passed, their
  second argument, which was always the same as the first, is now used to pass
  the sub plugin keys. This affects *all* instrument plugins.
* Plugin.h: Add more virtuals to `SubPluginFeatures` in order to draw logos
  and images into instrument selector widgets
* LadspaSubPluginFeatures: Implement the `displayName` virtual because the
  new behaviour to resolve displayNames is to first look at the
  SubPluginFeatures, which, without override, returns the superior plugin's
  name (Plugin.cpp)

Additional:

* PluginFactory.h: Allow setting up search paths without discovering plugins
  yet
* Plugin.h: Add full documentation (should be checked)

1d5cb23385 File and class renames part 1
Most files and most of the core classes and their methods have been
renamed to match new coding style conventions:

391 files changed, 25400 insertions(+), 25598 deletions(-)

Furthermore splitted some files where model and view classes were
declared or implemented together in the same file.

Should be tested thoroughly as I might have missed renaming some virtual
methods or SIGNAL/SLOT parameters.
