DRC generates digital room correction FIR filters to be used within HiFi systems in conjunction with real time convolution engines like BruteFIR. License: GNU General Public License (GPL) Changes: A new method for the computation of the excess phase component inverse has been introduced. Sample configuration files for 48 KHz, 88.2 KHz, and 96 KHz sample rates have been added. The homomorphic deconvolution procedure has been improved to avoid any numerical instability. A new Piecewiswe Cubic Hemite Interpolating Polynomial (PCHIP) interpolation method, providing monotonic behaviour, has been introduced in the target response computation. All the interpolation and approximation procedures have been rewritten from scratch to provide better performance and accuracy.
