Marazmator 2.0

Marazmator 2.0, a freeware experimental virtual synthesizer .

Marazmator was written in Delphi and the developer spent over ten years making it (according to the info available in the official product announcement). The fact that the plugin was in the making for such a long period of time is probably the reason why the GUI is so small by today’s standards (only 560 pixels wide). On the other hand, Marazmator is a very stable plugin, which is obviously a positive result of such a long development cycle.

DQ65 Free Dynamic Equalizer

DQ65 is a 5-band dynamic equalizer with a simple yet quite effective workflow. The plugin features two gain controls per band, one for louder one one for quieter parts of the signal. By controlling the value of this two parameters, it is possible to process the signal in ways which wouldn’t be achievable with a standard parametric EQ.
