Aphex Aural Exciter Type B

The Aphex Aural Exciter Type B brought one of the most talked-about studio processes of the 1970s into a more practical hardware format. Instead of simply boosting treble with EQ, it generated new upper harmonics and blended them back with the dry signal, making vocals, drums, and full mixes sound clearer, brighter, and more forward.

That difference matters. Where EQ can make a track louder or harsher, the exciter effect tends to feel more like added presence and intelligibility. The earlier Aphex process famously began as a rental-only service; by the time the Type B arrived, the idea had become a real product category and a studio staple.

How It Works

  • Filters a sidechain signal before sending it into a harmonic generator
  • Creates upper-frequency content rather than only boosting what is already there
  • Blends the processed signal back with the dry path for added presence and detail

Legacy & Evolution

The Aphex exciter concept moved quickly from expensive studio secret to mainstream mix tool. Engineers used it on lead vocals, guitars, drums, broadcast chains, and even full program material. Modern software versions still chase the same promise: more air and clarity without the brittle side effects that simple treble boost can create.
