/ SC Reverb
This VST plugin is
implemented for performance evaluation of the
Switched Convolution Reverberator structure, which is proposed in the
AES paper1. This
reverberator algorithm requires little memory and low computational
complexity and readily generates high echo densities, so that it is
appropriate for mobile devices and the like.
Reverb has some controllable parameters as shown below figure. It
consists of mix level, reverberation time in time/freq., pre/late-delay
time, etc. Among them, 'Method', 'Noise Type' and 'Late Only' are used
for demonstrating the performance of each structure in the AES paper1.
Display panel provides three different views, which can be switched
using the 'display panel selector'.
For the details of 'Method' and 'Noise Type' parameters, please
refer to the
project page on the switched convolution reverberator.
- IR: Impulse response in the time domain. It consists of
direct sound(red), early reflection(green) and late-field reverb
- RT: Reverberation time in the frequency domain. it can be
controlled using low freq RT, high freq RT and transition freq.
- EQ: Reverb EQ filter response. It has 1st-order IIR
Shelving filter structure.
This VST plug-in is
implemented using VST audio plug-in SDK v2.4 and VSTGUI lib.

This plug-in is developed for academic purposes. For the
professional use, it might have to be more optimized in computational
complexity; e.g., using Intel's Streaming SIMD Extention (SSE).
