THE ENGINEERING TOOLS
Each filter type provides a method of accessing and utilising the
DSP resources of the Huron system. Filters play off latency,
length and the number of buffers available within the Convolver
tool with the DSP resources in the system.
1. Click the located to the right of the Filter Type Box.
2. Select the appropriate filter from the drop down menu.

Tip: A single Convolver can only use
one type of filter. To have a system
using different types of filters, simply
invoke more instances of the
Convolver from the VRack.
Creating Programs
↓ To create a program
Table 1 — Filters available to the Convolver
The list contains the number assigned by Lake to the filter type,
the length of the filter in samples, its latency in samples (ie.
how many samples delay there is between data arriving at the
filter and leaving the filter), its latency expressed in
milliseconds (assuming a 48kHz sample rate), the number of
DSP processors this filter uses when running and the number of
buffers, or concurrent programs which can be held in memory
to allow fast switching.
The Convolver calls a collection of filter structures a Program.
Up to 512 of these Programs can exist within the Convolver,
however only one will be active at a time.
1. Click on Add in the Program List.
