OldSkoolVerb (Windows/Mac, VST/AU) by Voxengo is a freeware algorithmic reverberation for professional music production applications, and implements a kind of “classic” stereo reverb algorithm, the result being a very clear spatial image that blends well with the mix. Works on almost every audio material and is well suited for modern music productions. It features a very diffuse and modulated vintage reverb sound, being capable of fast build up time, also with long reverb sounds. TAL-Reverb-4 (Windows/Mac, VST/AU) by Togu Audio Line is an easy-to-use reverb plugin drawn from the high quality reverb implemented in TAL-Sampler.
