Latest news

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 improved.

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.
