Overview of the Convolver Setup
The Convolver Tool
The Convolver tool provides a flexible and powerful interface
to long, low latency convolution technology.
Each instance of the Lake Convolver requires the creation of a
setup file, which defines a list of Filter programs. A Filter
program is itself a definition of both the structure of a
mathematical filter and its coefficients that are loaded from an
impulse response file.
The Convolver tool is organised so that users can quickly
switch between the coefficients in the list of Filter programs
using MIDI, keyboard or mouse inputs. This ‘fast switching’ is
made possible by loading the Filter program coefficients into
the DSP card’s onboard Dynamic Random Access Memory
(DRAM).
• The Convolver utilises low latency convolution algorithms
to provide real-time convolution.
• Provides up to 278,244 tap filters.
• Fully integrated with Lake Technology’s VRack
environment.
• Allows fast switching between Filter programs to allow the
A/B comparison of impulse responses.
A Convolver Setup can be thought of as a series of nested
elements. These nested elements are described in the diagram
below.
