Release of TASCAR for ARM Linux / Raspbian Buster.
TASCAR 0.213 released
A parametric HRTF simulation binaural receiver type was
added. The parametrization is based on the Spherical Head
Model (SHM) by Brown and Duda (1998) and includes three
further low-order filters. This receiver is an outcome of the
bachelor thesis of Fenja Schwark.
TASCAR 0.212 released
Source directivity defaults now to omni-directional for
volumetric (diffuse) receiver types. This can be overwritten for
new source directivity types, e.g, to account for average
diffuse radiation frequency response.
TASCAR 0.211 released
A partitioned convolution for for rendering diffuse
reverberation based on recorded B-format impulse responses was
added, and the simple feedback delay network (FDN) was
TASCAR 0.210 released
A receiver type for rendering to ITU 5.1 speaker layouts was
added. Furthermore, a new diffuse reverberation concept was
developed, to allow diffuse reverb also in offline simulation
and without recursive signal routing. A simple feedback delay
network (FDN) was added as a prototype algorithm.
TASCAR 0.209 released
Addition of A weighting to level metering, some GUI improvements and bug fixes. Switching of meter weighting at run-time is now possible.
TASCAR 0.207 released
Improvements of the content authorship and right management system.
TASCAR 0.205 released
Implementation of arbitrary order 3D HOA encoding and decoding, with mode matching and ALLRAD decoder.
