{#image172}A memorable show during the Elektrafestival was the Laser Sound Performance by Edwin van der Heide. He used two lasers and (I think) motorized mirrors and filters to create laser patterns on the wall and in the smoke filling the space. The sound was mostly sine tones, sawtooths and various types of noise at an extremely loud level (even with ear plugs). Not really sure how he did it, but there was a really tight synch between the movement of the lasers and the sounds....

{.imagelink}The installation Spatial Sounds (100dB at 100km/h) by Marnix de Nijs and Edwin van der Heide. Spatial Sounds 100 dB at 100 km/h was set up at Usine-C during the Elektrafestival. A speaker is mounted on a metallic arm, rotating around at different speeds dependent on the people in the room. Ultrasonic sensors detect the distance to people in the space and changes the sound being played as well as speed of rotation (more technical info here)....

Came across the web page of Frank A. Russo, and found a very interesting paper on Hearing Aids and Music discussing the auditory design of hearing aids: Whether the hearing aid wearer is a musician or merely someone who likes to listen to music, the electronic and electro-acoustic parameters described can be optimized for music as well as for speech. That is, a hearing aid optimally set for music can be optimally set for speech, even though the converse is not necessarily true....

From the web site of the Wireless Networking in the Developing World project: The massive popularity of wireless networking has caused equipment costs to continually plummet, while equipment capabilities continue to increase. By applying this technology in areas that are badly in need of critical communications infrastructure, more people can be brought online than ever before, in less time, for very little cost. We hope to not only convince you that this is possible, but also show how we have made such networks work, and to give you the information and tools you need to start a network project in your local community....

{#image164}We are currently working with the Phantom Omni haptic devices at McGill, but unfortunately they are rather expensive. I have been looking forward to test the Novint Falcon which is supposed to sell for around $100, but after being in touch with the company it seems like they will not start shipping devices before next year. I really think such devices will change the way we work with computers. The computer experience has been 2-dimensional way too long, and from my initial testing of 3D haptic devices shows how much potential is lying in this type of human computer interaction....

It took me a couple of weeks to discover that much-rumoured Google Calendar has finally been released. I have tested it, and it looks and works very well. As many other Google services it is ajax based, so that the whole page does not have to be reloaded every time you do an edit. Not entirely as functional as a standalone application, but a dream to work with compared to other online calendars....

In a blog note questioning Web 2.0 Tim O’Reilly writes that Web 2.0 is the era when people have come to realize that it’s not the software that enables the web that matters so much as the services that are delivered over the web. Web 1.0 was the era when people could think that Netscape (a software company) was the contender for the computer industry crown; Web 2.0 is the era when people are recognizing that leadership in the computer industry has passed from traditional software companies to a new kind of internet service company....

 I am reading e-mail using IMAP, and don’t want to store large attachments on the server. Depending on the computer and platform I am working on, I use several different clients (Firefox, Opera, Pine, SquirrelMail), but I am using Apple Mail as my main client. For some time I have been annoyed that there was no way to remove attachments from e-mails. This was based on the assumption that all necessary and relevant features are available in the contextual menus that popup when right-clicking on a message....

In a discussion on using OSC to communicate over networks, Darryl just mentioned that OS X (apparently starting from Tiger) has the possibility to send MIDI messages over the network. I wonder how I have managed to oversee this feature, since it is sitting there as an option right in the Audio MIDI setup. The help file reads: You can use the MIDI network driver to send and receive MIDI information between computers over a network....

My post over at the Open Sound Control forum: I guess we are all trying to get rid of MIDI, but as long as we have tons of gear around, it would be good to have a generic way of describing MIDI information in OSC. Perhaps I am missing something obvious, but I have looked around and haven’t found any suggestions for a full implementation of MIDI messages as an OSC address space....
