Gestural Processor

Frahm is a multi-spatializer, using force fields.

Built on top of a particle-based force field system, Frahm takes the movement of particles that it simulates and treats them as sound sources in three dimensional space.

Frahm allows you to select from ten different force-field algorithms, adjust their parameters and even mix two of them together for your desired result.

When multiple instances of Frahm are layered on top of each-other in your DAW, you can create highly intricate  soundscapes, all in real time.

Frahm is able to operate it’s spatial engine in multiple different modes depending on your intended application. Binaural for headphone-optimized listening, and stereo for conventional speaker setups.

The heart of Frahm is it’s “force field” particle system. Essentially, these functions take in a position of a particle and return a direction for the particle to move in. The particle then gets nudged in that direction.

Each of one of Frahm’s force-field algorithms have their own parameters which can uniquely affect the behavior of the algorithm. Couple this with the ability to cross-fade between two different functions, Frahm can create sound movements in almost any fashion.

Outside of the individual algorithm parameters, Frahm also features “Meta parameters”, such as movement speed,  movement basis (that is, which axis particles will be travelling along), and simulation size.

Optimized Doppler Shift

Spatializing with doppler-shift sounds great. What sounds better is doing it for every single particle, all the while using only a fraction of the CPU usage as other plugins doing fractional delays.

Made for Performing

Resize, freeze, and alter Frahm’s internal audio buffer with minimal artifacting all in real time.

Peek Into the Chaos

Frahm’s OpenGL 3d viewport lets you see exactly how your particles are moving. Use the X / Y sliders to change the view angle of the space, or just drag your mouse.

It it gets better though; Enable “Force Field” display mode in the viewport’s options to get an understanding of what movements will occur depending on where your particles are located.
