Audio Toolkit: Create a FIR Filter from a Template (EQ module)

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.

Announcement: ATKChorus 1.1.0 and ATKUniversalVariableDelay 1.1.0

I’m happy to announce the update of the chorus and the universal variable delay based on the Audio Toolkit. They are available on Windows and OS X (min. 10.11) in different formats.

This release fixes the noises that can arise in some configuration.

Audio Toolkit: Recursive Least Square Filter (Adaptive module)

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.

AudioToolkit: creating a simple plugin with WDL-OL

Audio Toolkit was started several years ago now, there are more than a dozen plugins based on the platform, applications using it, but I never wrote a tutorial explaining how to use it. Users had to find out for themselves. This changes today.

Playing with a Bela (1.bis): Compile last Audio Toolkit on Bela

A few months ago, I started playing with the Bela board. At the time, I had issues compiling Audio ToolKit with clang. Since then and thanks to Travis-CI, I figured out what was going on. Unfortunately, the Beagle Board doesn’t have complete C++11 support, so I’ve added the remaining pieces, and you need also a new Boost.

Playing with a Bela (1): Turning it on and compiling Audio Toolkit

I have now some time to play with this baby:

Beagleboard with Bela extension

The CPU may not be blazingly fast, but I hope I can still do something with it. The goal of this series will be to try different algorithms and see how they behave on the platform.
