Phazor is a free effect plugin, which emulates the phaser effect found in the Virus synthesizers, which helped make its characteristic sound. A lot of time was devoted to make it sound very close to the original and every control has been carefully adjusted to behave just like the phaser from the Virus. It has selectable 1 to 6 stage all-pass filters controlled by an LFO, with spread and feedback controls. The plugin is highly optimized and its CPU usage is minimal, allowing for multiple instances to be used in a project.

Credits go to J. Bradford Hunter for his help with the coding and optimization!



Available for Mac and PC, 32 and 64 bit. Ported by Andrey Starostin.

    Hi Adam
    My Imac does not seem to want me to download this?
    Is this usual?
    Best wishes—Jim

      Have you perhaps tried a different browser to download the file?
