Matthieu Brucher updates Audio Toolkit to v1.4.0

Matthieu Brucher has announced an update to Audio Toolkit, a BSD-licensed audio processing library based on a pipeline concept. This release focused on efficiency on IIR filters as well as adding SVF filters, triode filters and support for the Intel compiler and ARM platforms.

Changes in 1.4.0:

• Added a LeachTriodeFunction for simpler tube filters.
• Added Intel Compiler support.
• Vectorized FIR part of IIRFilter.
• Refactored gain filters to enable vectorization.
• 256 bits alignment of internal arrays (with or without delay, the first element to process will be 256-bits aligned).
• Starting support for ARM platforms (not optimized yet).
• Added a FlushToZero class used in Python interface so that it is activated when process () is called.
• Added a 1 - input filter with Python wrappers.
• Removed the old SD1 filter, replaced it definitely with the SVF version.
• Added a TS9 overdrive filter (SD1 without the asymmetry) with Python wrappers.
• Added a Tube2Filter with wrappers, adding the plate-grid capacitor in the equations, stabilizing them better (requires Eigen).
• Added a family of triode preamplification filters with Python wrappers (requires Eigen).
• Added a class A NPN preamplification filter with Python wrappers (requires Eigen).
• Added a buffer filter with Python wrappers.
• Added a new Diode clipper with trapezoidal rule with Python wrappers.
• Added a new version of the SD1 distortion with ZDF mode and Python wrappers.
