Thicker sound, same character. Tetraplopia is a four-voice stereo doubler that adds density without adding color, movement, or wash… unless you want it to.
Own the stereo field
Tetraplopia takes you far beyond basic double-tracking. It lets you craft your stereo image exactly the way you want it.
You get four independent voices, each with Level, Spread, Delay, and Detune controls. Position them in time and space, adjust their intensity, and detune them as you like.
Even at default settings, the difference is immediate. Here's an electric guitar running through Amp Squeezer and then into Tetraplopia.
Amp Squeezer only
Amp Squeezer + Tetraplopia
Global macros
Tetraplopia exposes global Spread, Detune, and Delay macro controls to quickly adjust all amounts at once.
Then there's an Fx parameter that does more than simple dry/wet mix: it smartly scales all voices and their settings simultaneously, giving you a cohesive, musical effect.
Input
Global macros at 100% (default)
Global macros at 200%
Studio-grade upmixing
Tetraplopia is based on studio-grade upmixing technology for high-end immersive audio. That is why it can deliver almost colorless widening, free of bad phasing and combing artifacts… unless yo choose otherwise.
For example, using two centered voices with no detune or delay, it stays remarkably close to the input signal.
Input
2 voices, centered, no delay, no detune
Otherwise, hard-panning those two voices to extreme left and right gives you a result that is really close to traditional double-tracking.
Input
2 voices, hard-panned, no delay, no detune
Using the same settings on four voices evenly distributed across the stereo field creates a more subtle, organic widening.
Input
4 voices, evenly spread, no delay, no detune
Sounds great, plays fast
Tetraplopia is built to meet the highest sound quality standards while maintaining maximum playability.
Specifically:
- Its near-linear operation generates no audible aliasing.
- It adds absolutely no latency.
- It is based on advanced upmixing technology borrowed from high-end immersive audio production.
Go get it!
Curious to hear what you do with it.
