Lowender

Lowender is a powerful audio plug-in designed to be a subharmonic synthesizer reminiscent of classic analog dual-band bass enhancer circuits. More than a simple EQ, the Lowender creates new bass content from your existing audio material.
From post-production houses to disco floors, from high-powered live sound to rock, dub, and metal studio productions, the characteristic rumble of the subharmonic synthesizer has been an engineer’s best-kept secret for years. Now, finally, you can get those low lows from within your favorite DAW application!
While taking the classic “Boom Box” sound as its core, the Lowender expands on the concept in several ways. First, it offers switchable frequency ranges, so that the low end frequencies generated can be selected to fit the program material.
Second, the generated subharmonics pass through a gate tailored for low frequencies, which is useful for cleaning up unwanted bass rumble (e.g. from between kick drum hits in a drum loop).
Third, the Lowender passes the bass material through an output section comprised of an overdrive circuit and a lowpass filter. Driving or compressing the newly generated low frequencies is essential for evening out their dynamics, and will allow them to sit well in a mix. The variable lowpass filter is provided to shave off the higher harmonics of the overdrive and create a smooth low end - or you can leave some of them in, for raspier bass sounds.
