Acoular

Supports Python 3.7, 3.8, 3.9, 3.10, 3.11 on Linux, MacOS, Windows

* New class MetricEvaluator to evaluate the performance of source mapping methods according to Herold and Sarradj (2017)
* New class PointSourceConvolve to blockwise convolve an arbitrary source signal with a spatial room impulse response
* All filter classes derived from Filter use SOS filters now
* No more version restrictions for scikit-learn
* Speedups for numba jitted functions by enforcing C-contiguous arguments and the efficient use SIMD processor instructions
* Class BeamformerOrth now reimplements orthogonal deconvolution to be even faster and has a slightly different interface
* Simple benchmark suite to compare the performance of Acoular core routines on different computers
* Some internal rework in grid and sector classes
* Test coverage is improved
* Bugfixes:
* minor bugfix for convective amplification in BeamformerCleantTraj and BeamformerCleantTrajSq
* bugfix in some attributes of ImportGrid

New class FiltWNoiseGenerator

New classes SphericalHarmonicSource, Linesource, MovingPointSourceDipole, MovingLineSource

New class TimeConvolve

Speedups:

CSM works now in parallel and is faster

frequency domain beamformers are abaout 30% faster

time domain beamformers and CLEAN-T is now about 10 x faster

Unittests for all major features, much better coverage

Bugfixes:

integration sectors

new grid classes from 20.10 are now imported into module namespace
