when you hear "matrix" and can think of more than just keanu reeves, 
this library might be for you.

apart from lots of improvements, bugfixes and cleanups, iemmatrix 
includes the brand-new [mtx_convolver~] for adavanced MIMO-processing 
and the plethora of possibilities it opens up for 3D audio effects and 
the like.

as usual, packages are available on deken (and will be uploaded to 
Debian in a second).

if you happen to be around Düsseldorf (Germany) this weekend, there will 
be a workshop exploring the new features of iemmatrix during the 
Tonmeistertagung (Saturday, 11:00am), held by my colleagues Hannes 
Pescoller & Franz Zotter:

# Prototyping Interactive 3D Audio Applications in Pure Data with 
Multichannel Connections and [mtx_convolver~]

This tutorial shows how to arrive at 3D Audio implementations in the 
graphical audio processing language Pure Data. By the relatively young 
multichannel signal connections and the brand new [mtx_convolver~], Pd 
becomes a very exciting playground to implement immersive 3D audio 
effects and interactive environments. For instance, applications 
implementing convolution reverb or also binaural decoders for 3D audio 
in Ambisonics are easy to implement. Together with 
[mtx_spherical_harmonics], [mtx_*~], and multichannel signal connections 
as powerful tools, various applications, also interactive, time-varying 
ones, are shown in the tutorial. In particular, simple examples are 
shown for binaural decoding, for encoding from spherical microphone 
recordings, or for decoding to beamforming spherical loudspeakers, and 
last but not least, an Ambisonic shoebox-room image-source model.

happy patching.
