Rush Hour

In 2015 Bitsphere was working on the project “Rush Hour”. Here is the first description as found on the website:

The installation “Rush Hour” renders sound according to image data gathered from a distant camera in public trespassing knots to an array of loudspeakers in an exhibition space in real time.

Intended for an outdoor installation the receiving unit may be installed in closed spaces too. This piece deals with the displacement of perception transformation of surveillance data and tracking of movement in formerly public spaces.

The detailed project description will be published later on.

Musical Biosensor by Marco Donnarumma

note_symbolIn the recent days Bitsphere did some hardware assembling due to the great open source work of Marco Donnarumma called x-th sense. An open hardware project which aims to amplify muscle sounds. The local hardware distributor here in Switzerland offered all the pieces need for the assembly except the “protokit” mentioned in the xth-sense documentation and the sensor is build in less than an afternoon by a newbee to hardware assembling for the on-line documentation is really detailed.

Bitsphere replaced the protokit with a “Hammond Manufactoring 1593KBK Handheld Box”, sawed a piece out of an epoxy fibre-glass labor card (the RE523-LF by Roth Elektronik) which fits in the box and screwed it into the box. That is about the pieces the original kit consists of.

To get the software running was the harder part. It was not that easy to get the required version of puredata extended. Finally it turned out there is a repository for the beta builds with the required versions. Then the directory names mentioned in the x-th sense how-to have to be created on the local disk the very same.

For those interested in readings about body sounds you find an article about biomusic in the Journal of Sonic Studies.

QR code sonification video and sound file

bitsphere_microAs announced in January Bitsphere created another oneminute video. Other than planned earlier this year it is not an augmented reality video but a study of a QR code acting as a sequencer and visuals related to this topic. Lack of evidence in the earlier concept led to this change of concept. Sonification of a QR code was on Bitsphere’s wish list for a long time. As usual the video will be posted on the youtube channel as soon as the oneminute festival in Aarau is over.

In the meanwhile Bitsphere is very proud that the Amsterdam oneminute foundation accepted last year’s video for occasional use in various contexts. So far no screening seems planned but you will be kept up to date when this changes.

Furthermore there is an uploaded example of a QR sonification on soundcloud. The root is the micro QR code in the post header image you find at the top left of this post.  Thoughts on QR codes you may find here on this blog. As usual you are invited to leave a comment in the comment section!

Bitsphere One Minute Video 2012

Once again Bitsphere wrote an animation video for the Oneminute video festival in Aarau, Switzerland. This years video consists of colors and music which change in an algorithmic pattern:

Bitsphere decided not to let the video run in the competition blocks, so it was screened only once in Aarau. If anyone knows about a one minute video festival anywhere else in the world, please drop a line so Bitsphere can send it there.

Is there such a thing like abstract music?

Music always is in time as a given function thereof. The invention of the recording machine has added recursion to this formula and changed music as a we perceive it and how it is accessible. Some musicians used to bring loopers or other devices on stage during the last decades. Some play music which they call ‘musique sérielle’ which provides some answers to the new listening habits.

When comparing the shift in the audio world before music recording as it might was and afterwards to the painting world before and after inventing photography there is obviously one big difference: In painting there was a shift to abstract painting which cannot be found as such in music.

What do you think? Is this observation true? Please leave a comment in the comment section below this post if you have any thought about this subject!

Guerrilla Web Sounds

Most of the websites are silent. This means that there is no sound. There is no technical obstacle which hinders people to add sound or even music to their websites and there are enough sound designers out there who would be glad to do some work for websites.

The reason web designers do not use sounds is that users often get disturbed by the sounds. Everyone who worked in a strict office knows that people do not only hide their surfing abroad work tasks from their boss but also from their co-workers (they could tell the bosses). At some offices but mainly at home people tend to listen to music while using their computer. In both cases users of a website do not need an acoustic signal. And yes, it also decreases download speed of the site.

The solution to this problem might be “guerrilla sounds”: Very short and vague sounds that might as well come from another source. They would be small enough to download quickly and not annoy but amaze people visiting your site.

So, what do you think about the idea? Please respond in the comment section or post links to any “Guerrilla Sound Page” found out there! Thank you.

Realtime Composing

The “Blind Ear Music” project comes with a new and fresh approach to computer aided composing. They compose music in real time and let human players interpret the music:

This new approach to live performing music does not care about sample rates or room sound as it works with formal assignement of music to each individual human players with classical instruments.
