[23.5.2014] Dr Damian Murphy from University of York, UK was visiting us for two months. Very nice and inspiring visit as always. Thanks, Damian!

[15.5.2014] Doctoral thesis viva of Craig Webb in Edinburgh University. Well done Craig - congratulations!

[2.5.2014] Hannes Gamper defended his doctoral thesis - congratulations! Brian Katz from CNRS/LIMSI acted as the opponent.

[3.4.2014] I had the pleasure to give a plenary talk on "Current Trends in Room Acoustics Modeling" in the EAA Auralization Symposium.

[2.1.2014] I started as the head of Department of Media Technology.

Old News

[30.8.2013] We have a PhD student opening in our team. The topic of the research is room acoustics modeling and optimization, and it is funded by this 4-year Academy of Finland project.

[13.5.2013] The AES Convention in Rome was very nice. Very good to see and discuss with people! In addition, I was awarded with the AES Fellowship Award there :-).

[24.4.2013] Dr. Stefan Bilbao from University of Edinburgh was visiting us for two weeks. Very good discussions and nice start to a new study!

[18.4.2013] Our manuscript "Room Impulse Response Synthesis and Validation Using A Hybrid Acoustic Model" was accepted to the IEEE Transactions on Audio, Speech and Language Processing.

[13.3.2013] The program for the ICA is online. The "room acoustics computer simulation" is divided into three sessions that will take place on Thursday and Friday morning. The "GPUs in acoustics modeling and DSP" is scheduled for Friday morning. So, those two are unfortunately overlapping, and both of them have very interesting papers! Hope to see many of you there!

[1.3.2013] Both of our submissions to ICASSP were accepted!

[1.2.2013] Prof. Jose Javier Lopez from the Technical University of Valencia arrived. He will be visiting us until the end of April. Welcome, Jose!

[15.11.2012] Deadline for the ICA abstract submission. We got 35 abstracts to the Room Acoustic Modeling Session (organized jointly with prof. de Vries) and 10 abstracts to the GPU computatoin session (organized jointly with Dr. Hursky). Thanks to all the contributors!

[1.11.2012] Professor Dinesh Manocha from UNC was visiting us, and he gave a very exciting presentation on crowd simulation.

[22.10.2012] I gave an invited presentation in the ASA Meeting in Kansas City. The presentation was an introduction to our JASA paper "Modeling incoherent reflections from rough room surfaces with image sources"

[20.9.2012] Our "Spatial High Frequency extrapolation" paper by Alex and me got a "level-2 best-paper nomination" in DAFx'12.

[17.9.2012] My tutorial on audio signal processing with GPUs at the DAFx'12 conference was well received.

[30.8.2012] The 'Room acoustics' session organized by Ning Xiang and myself in Internoise at NYC had 23 presentations! Thanks to all the presenters!
