Plug-ins / SC Reverb

This VST plugin is implemented for performance evaluation of the Switched Convolution Reverberator structure, which is proposed in the AES paper¹. This artificial late-field 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.

Description

SC 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.

SC Reverb Description

Display panel provides three different views, which can be switched using the 'display panel selector'.

IR: Impulse response in the time domain. It consists of direct sound(red), early reflection(green) and late-field reverb sound(yellow).
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.

For the details of 'Method' and 'Noise Type' parameters, please refer to the project page on the switched convolution reverberator.

[Note]
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).
