Dual Acoustic Delay Line
Echo Cube is a dual delay plugin inspired by the Cooper Time Cube, a rare analog delay system that achieved echo without tape or electronic delay circuits scush as BBDs. The original unit created delay by sending audio through long coiled tubes, where time was defined by the physical propagation of sound through air.
Echo Cube recreates and expand this concept with two independent delay lines, A and B, each offering dedicated time, feedback, and level controls. Three models are available: Time Cube faithfully recreates the original hardware, while Garden Hose and Corrugated are experimental, DIY inspired variations designed for sound design, expanding on the physical principles of the original unit.
The delay lines can be combined using multiple routing modes, including serial, parallel, ping pong, mono sum, and mid/side, allowing precise control over delay interaction and stereo image shaping.
A Brief History of the Time Cube
The Cooper Time Cube was developed in 1971 by Duane H. Cooper and Bill Putnam as an alternative to tape and electronic delay systems. Rather than storing audio electronically, it created delay by sending sound through long coiled tubes, using air as the delay medium. This mechanical approach produced very short delays of approximately 14 ms on one line and 16 ms on the other, or a combined cascade total of around 30 ms. Short enough for doubling and Haas-type effects rather than long echoes. The result was a distinctive echo with acoustic filtering and phase character unlike anything achievable with contemporary tape or BBD designs. With only about 1,000 units ever made, the Time Cube became a rare studio fixture with a strong following for its unique sound.
This emulation is based on an original unit from the AudioThing collection, in excellent condition, fully serviced and carefully maintained.
While the delay times were fixed and very short compared with contemporary tape echoes or later digital units, the Cooper Time Cube’s acoustic transmission medium and transducer setup gave it a unique frequency response and tonal footprint. In practice this meant its output added a sense of width and presence more than pronounced repeat tails, making it especially useful for doubling, subtle spatial enhancement, and mix placement rather than obvious slapback echoes.
The physical construction contributed to its signature character and helped it earn a dedicated following among engineers despite its limited feature set.
