Until now, Mixer not only was responsible for rendering audio buffers
but also managed writing them to audio backend (through a FIFO) and
handled various quality related parameters.
All this functionality has been moved into the new AudioOutputContext
class. It glues together AudioBackend (formerly called AudioDevice),
global quality settings and the Mixer.
The AudioOutputContext class creates a FifoWriter which calls
Mixer::renderNextBuffer() and writes the output into the BufferFifo of
the AudioOutputContext it belongs to. The BufferFifo is read by the
according AudioBackend which belongs to the AudioOutputContext as well.
The AudioOutputContext also handles resampling in case the AudioBackend
wants the buffers in a different samplerate.
During this rewrite the Mixer class and the according source files have
been renamed from "mixer" to "Mixer". This results in small changes
all over LMMS' code base.
All versions of OS X except Snow Leopard ship GCC 4.0 which does not
understand the "-finline-functions-called-once" flag. Therefore do not
use this flag when building for OS X.
This reverts commit dd260245ec.
The commit fixed the compilation problem but according to upstream
causes new problems because of the huge data structures on the stack.
Upstream provided a better patch which will be applied next.
The std::vector::data() method is a special feature of GCC and
therefore not portable. This causes a compile failure of CALF plugin
on OS X. Therefore I replaced the code with standard arrays
allocated on stack.
Upstream needs to be informed about this patch.
Thanks to Daniel Klaffenbach for pointing out this issue.
Source directory structure of the CALF plugin shipped with LMMS was
not equal with original one which makes cherry-picking commits from
CALF Git impossible.
We can safely make fillDescriptionWidget() and listSubPluginKeys()
const methods. Furthermore descriptor pointer to listSubPluginKeys()
can be const as well. Might allow more optimizations by the compiler.
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.
After (exactly) 5 years of silence, there's a new relase of TAP LADSPA
plugins. It fixes issues on 64 bit machines, uninitialised variables
and denormal issues.
As per popular demand I added CALF LADSPA plugins to be shipped with
LMMS. After some minor modifications the plugins compile and work on
win32 platform too.
* cleaned up code and improved coding style
* removed old SINGLE_SOURCE_COMPILE macro relicts
* use QString::toUtf8() instead of QString::toAscii() wherever possible
Updated CAPS plugins to version 0.4.3 - changes:
* basics.h cleanup / comments
* minor Makefile cleanup
* comment cosmetics
* Eq and Eq2x2 per-band Q changed to 1.414 (= 1 octave)
* Eq lowest band default value fixed to read 0
* Niclas' fix for the bessel function implemented
* uninitialised plugin states eliminated thanks to Damon
* linker options for OSX added to the Makefile

The new CPU framework replaces the old BasicOps framework. It is more
flexible and the build process isn't such a mess anymore (pre-compiled
assembler files etc.). It will hopefully see some improvements and
extensions soon.

There were various (trivial) problems with settings of the build system
which prevented LMMS from being built on OS X.
Thanks to Daniel Klaffenbach for providing his Mac for development
purposes.

When global samplerate changes, settings of a LADSPA effect are stored in
a temporary object, the effect is reloaded and the settings are restored.
However, controller connections weren't restored properly as the connections
were not finalized. This commit fixes the issue.
