Since I’ve been using it quite a bit lately and it’s the top result on Google for “WAV Builder”, I’ve added some new features to WAV Builder, which are: selectable bit depth: you can now create WAV files with a bit depth of 8 bit, 16 bit, 24 bit or 32 bit floating point more… Continue reading New features in WAV Builder

Radial Vector Image Processing in JavaScript
I’m a noob when it comes to image processing algorithms. But when I tried to do something in GIMP that I could not find the right button for, I decided to create an image processing algorithm myself. Maybe there is a much simpler solution to this and maybe you can do it with one click… Continue reading Radial Vector Image Processing in JavaScript
Luhmann? Zettelkasten? Digitalisierung?
Heute wäre der bekannte deutsche Soziologe Niklas Luhmann 90 Jahre geworden. Entsprechend ist das Medienecho zurzeit groß: https://www.welt.de/kultur/literarischewelt/article171257947/Das-hoelzerne-Privatinternet-von-Niklas-Luhmann.html http://www.tagesspiegel.de/wissen/niklas-luhmann-zum-90-er-dachte-mit-dem-zettelkasten/20683794.html https://www.nzz.ch/feuilleton/das-genie-der-gesellschaftstheorie-ld.1335385 In den Artikeln ist auch von der zur Zeit stattfindenden Digitalisierung seines berühmten Zettelkastens die Rede. Ich betreue seit gut zwei Jahren am Cologne Center for eHumanities das technische Zusammenspiel dieser Digitalisierung, entwickle die Software… Continue reading Luhmann? Zettelkasten? Digitalisierung?
SEven – A Science Fiction Event Graph Generator
Create relativistic and non-linear timelines of Science Fiction stories. The web editor supports time travels, time dilation and alternate realities. Science fiction narrations often incorporate non-linear and relativistic timelines that occur because of phenomena such as Time Travel Time Dilation Frozen time Alternate realities/parallel universes Opposite direction of time flux relative to a reference system… Continue reading SEven – A Science Fiction Event Graph Generator
Stopping a Web Audio oscillator at cycle completion (or zero-crossing)
When calling osc.stop(), a running oscillator is stopped immediately, which can result in a nasty click. This is because the oscillator is stopped right in the middle of a cycle. Here’s a nice tutorial on how to get rid of the click, using automation curves for smooth gain fade-outs: http://alemangui.github.io/blog//2015/12/26/ramp-to-value.html But there’s another way: When stopping… Continue reading Stopping a Web Audio oscillator at cycle completion (or zero-crossing)
A piano sustain pedal to MIDI USB adapter
I like my MIDI USB keyboard. But unfortunately, it does not have a sustain pedal jack. That is why I built an adapter, which translates the pedal input into MIDI messages. All it took was an Arduino Leonardo (Pro Micro module with ATmega32U4), a breadboard, a 7-segment LED display, two resistors, 2 toothsticks, a 6,3mm mono… Continue reading A piano sustain pedal to MIDI USB adapter
Martina Gödel, Johannes Schmidt, Sebastian Zimmer – Niklas Luhmanns Zettelkasten: ein “preadaptive advance” digitaler Datenbanken?
On September 26, the Luhmann team and me will be talking at Basis Zwei in Hannover about the challenges of creating the Niklas Luhmann Archive. Please find more details here: http://basiszwei.tumblr.com/post/148837338530/die-verfl%C3%BCssigung-der-archive
Der Ton beim Tatort ist NICHT schlecht! Er ist zu gut!
Im Netz mehren sich die Beschwerden bezüglich einer vermeintlich schlechten Tonqualität beim Tatort: http://www.spiegel.de/kultur/tv/christian-ulmen-entschuldigt-sich-fuer-schlechten-tatort-ton-a-1011036.html http://www.t-online.de/unterhaltung/tv/id_77213226/mieser-ton-beim-tatort-t-online-de-erklaert-die-gruende.html Nun fordert Prof. Ingo Kock, Dekan der Fakultät Ton an der Filmuniversität Potsdam-Babelsberg, dass 70-Jährige den Tatort-Ton abmischen. Dabei gibt es auch andere Lösungen.
Uni Köln Campus with VR View
Boris Smus and Google have released another great little helper for putting VR content on the web: VR View. VR Views allow you to embed 360 degree VR media into websites on desktop and mobile, and native apps on Android and iOS. Source: https://developers.google.com/cardboard/vrview I tried it out today during a coffee break. I captured a “photosphere”… Continue reading Uni Köln Campus with VR View
Should your web audio app have a limiter?
Did you come across digital clipping in web audio apps? I certainly did several times (mostly in my own apps though). This undesired effect occurs when you play several sound sources at the same time, which results in a signal that is louder than the maximum of 0 dBFS. Since a digital system is unable to… Continue reading Should your web audio app have a limiter?
