This March was quite busy in terms of conferences. We have presented a number of papers at the
You can find the references and download some of the papers/presentations at my homepage.
In Matlab you can just type the first letters of a used command and press the arrow up key to get it back. In Bash you can do the same, but you have to press page up instead of arrow up.
If you want to have the same behavior in Bash as in Matlab, you can do it this way:
Create ~/.inputrc and add the following lines:
# Matlab like Bash history "e[B": history-search-forward "e[A": history-search-backward # Include system wide settings which are ignored # by default if one has its own .inputrc $include /etc/inputrc
Also add the following to your ~/.bashrc:
# Load inputrc export INPUTRC=~/.inputrc # Ignore multiple entries of the same command in history export HISTCONTROL=ignoreboth
Now the Bash history should work like the history in Matlab.
CTRL-C cleans the line, if you have searched for the wrong command.
In addition to that in Bash you can jump to last/next word in the command line by pressing CTRL-arrow left/arrow right.
…the full call for papers for the DAFX 2010 is here.
The DAFx conference is a meeting of all enthusiasts of signal processing, live-electronics, audio effects, music related disciplines, etc. who come together annually to discuss, present and publish their scientific and practical findings. To make it perfect, the schedule of the DAFx-10 also includes a social program with music, art, food, our city, and the countryside for its participants.

To simulate the behavior of the auditory nerve, you have to half-wave rectify your input signal.
If you have used an if statement in Matlab to do this, the following code is for you:
outsig = max( insig, 0 );

Time-reversal acoustic focusing and focused sources reproduced by Wave Field Synthesis (WFS) are closely related in the underlying physical concepts. However, the goal of time-reversal techniques is typically to concentrate acoustic energy at the focus point, whereas WFS aims at creating an acoustic impression. I have created two videos for my talk at the 127th Convention of the Audio Engineering Society in order to show the difference of the approaches.
The first video shows the reproduction of a focused source using a time-reversal technique on a very densely spaced loudspeaker array (illustrated by the black line). The speakers emit a bandlimited Dirac pulse with a bandwidth of 5 kHz.
Note, the video does not start at the time the pulses have been emitted by the loudspeakers.
The second video shows the reproduction of a focused source using Wave Field Synthesis
Note that the target listening zone is below the focus point.
Its clearly oberservable that the time-reversal technique creates two wavefronts that pass a listener, while WFS creates only the desired wave front within the target zone.
Alexander Lindau from the audio communication group of the TU Berlin has generated this amazing panorama of our circular loudspeaker array at Deutsche Telekom Laboratories:

The damping material has been added temporaily for measurement of binaural room impulse responses of our array.
Dear Visitor,
this is the BLOG of the audio group at the Quality and Usability Lab of Deutsche Telekom Laboratories. This BLOG discusses actual research topics and developments in spatial audio and audio signal processing. Please feel free to comment our posts!
