Ramsete 3.02 Novel Full Release (with bugfix) in now available (05/01/2018)!!!
Please go to the
download directory and get the
new complete installation package - no
password is required, and the program works
in "demo mode" also without the new USB memory stick!
the first publicly available software for
acoustical simulations based
on the Pyramid Tracing computing scheme,
which is quite different from traditional
Ray Tracing or Cone Tracing schemes.
Briefly, the Pyramid
Tracing algorithm is capable of solving the
sound propagation problems in large
enclosures or outdoors, following the
Geometrical Acoustics assumptions. It takes
into account specular and diffuse reflections over sound
absorbing surfaces, being the absorption
coefficient and the scattering coefficient defined over 10 octave bands.
Furthermore, it takes into account
diffraction over free edges of screens,
energy passing through the panels (sound
insulation), holes in large surfaces,
windows or doors made of a material
different from the surrounding surface.
Ramsete is also equipped with
a powerful tool for auralization: the results of the
simulation can be converted in a pressure impulse response, emulating
carefully an IR measured with an omnidirectional microphone
or with a binaural dummy head. By convolving anechoic speech or music
with these IRs, one gets an audible rendering of the acoustical
behaviour of a design.
