I’ve started working on adaptive filtering a long time ago, but could never figure out why my simple implementation of the RLS algorithm failed. Well, there was a typo in the reference book!
Now that this is fixed, let’s see what this guy does.
Series: Audio Toolkit algorithms
Exposition of some of ATK algorithms.
Last week, I published a post on adaptive filtering. It was long overdue, but I actually had one other project on hold for even longer: allowing a user to specify a filter template and let Audio Toolkit figure out a FIR filter from this template.
Vinyl has become trendy again, and as such, I’ve been asked to add some new filters in Audio ToolKit. Here is a small dive in RIAA land.
In release 2.2.0, ATK gained new EQ filters that are vectorized. These filters cannot be used to filter different bands from the same input signal (yet), but they can be used to filter in the same way several channels.
