Greetings All, Two items which may be of interest to those who have interest in convolution reverb and/or physical modelling for audio: 1) The following C++ sample and impulse response function generators are now available with PyGtk GUI: Boxster version 0.0.2 --- 3-D parallelepipeds (rooms) Drumster version 0.0.2 --- 2-D membranes (rectangular drum heads) Hammster version 0.0.2 --- 1-D hammered strings (e.g. piano strings) Pluckster version 0.0.2 --- 1-D plucked strings (e.g. guitar) The sample and IR generation are based on Green's function techniques. (Green's functions are used extensively in mathematical physics.) --------------------------- 2) The following program can be used to convolve IR's generated by the programs above with WAV files and to perform tasks related to convolution reverb: Mixster version 0.0.1 --- simple mixer and convolution reverb workbench Please see: http://home.earthlink.net/~davidrclark for links to detailed announcements. Please note that these are prototype programs, not production codes. I have recently developed these task-oriented versions from my research class libraries. Thank you for your attention.
