Audified has released a bundle of new and improved summing tube processing plug-ins based around its proprietary Summing Tube Amplifier (STA) technology.

The namesake STA (Summing Tube Amplifier) technology that the original and second-generation STA Effects bundle of summing tube processing plug-ins both benefit from uses two signal paths: one being processed by modulation or spectral change while the other remains unprocessed. Those two signals are mixed via vacuum tube circuitry models.

There are six second-generation STA Effects plug-ins — including an all-new, self-explanatory STA Delay addition with convenient control over TEMPO, DECAY, STEREO, PING PONG, HPF (Hi-Pass Filter), and LPF (Low-Pass Filter) parameters. All are available to purchase as a bundle for $129 from Audified’s online shop (https://shop.audified.com/products/sta-effects). STA Delay and STA Preamp can be bought separately for $49 each.

STA Effects are available to download directly from Audified as 32- and 64-bit AAX-, AU-, VST2-, and VST3-compatible plug-ins for Mac OS X (10.9.5 or newer) and 32- and 64-bit AAX-, VST2-, and VST3-compatible plug-ins for Windows (7-10).
