+The \tascar{} toolbox is designed for the creation and rendering of virtual acoustic environments \citep{Grimm2015a,Grimm2016a,Grimm2019}. With \tascar{}, users have the capacity to construct virtual acoustic `scenes', which can be rendered in real-time and experienced through almost any sound playback system.
 
 Notably, these acoustic scenes can be manipulated and explored interactively by the user in real-time, such as through the use of headphones and a joystick for directional control within the acoustic space. Both direct sound paths and image sources, created through a geometrical image source model, can be rendered dynamically.
 
-However, it's essential to clarify that \tascar{} is not intended to function as a room acoustics simulator. Rather, its aim is to offer a rapid and perceptually credible approach for representing virtual acoustic environments in real-time. \tascar{} is adept at creating dynamic, interactive environments suitable for a range of applications, from hearing aid development and assessment, adaptive changes in spatial configuration psychophysics, soundscape simulation, to computer games.

 %\tascar{} -- toolbox for acoustic scene creation and rendering -- is a software designed for rendering virtual acoustic environments \citep{Grimm2015a,Grimm2016a,Grimm2019}.  In \tascar{} we can design virtual acoustic environments, here called {\em scenes}, which are then rendered in real time and can be played using any playback system.  These virtual acoustic scenes created with \tascar{} can also be explored interactively by the user in real time, for example using headphones and a joystick to control movement in the acoustic space.  Direct sound paths as well as image sources generated by a geometric image source model can be dynamically rendered.  It should be noted, however, that \tascar{} is not a room acoustics simulator, and the goal of \tascar{} is not to accurately reproduce the sound field in a room, but to provide a fast and perceptually plausible method for representing virtual acoustic environments in real time.  The \tascar{} software is suitable for building dynamic and interactive environments that can be used in hearing aid development and evaluation, psychophysics with adaptive changes in spatial configuration, soundscape simulation, and computer games.
