I had to learn to walk again.
I had this feeling, when at the end of June I started work with the audiofiles which are going to form the basis of Time Lapse China. As if I were jumping, stepping from one discipline into another.
The sound to which I was listening I knew already. They are recordings which I made in 1986 (on cassettes) and in 2015 (digital) in China. In both cases I was using a special technique, called binaural recording, which gives a 3D sound sensation provided that one is listening with earphones.
In May this year I asked Leo de Klerk, inventor of the OMNIWAVE, a revolutionary loudspeakersystem, if it was possible he would grant the usage of these speakers.
He was keen with interest. Because of his ‘inauble’ loudspeakersystem it became possible to walk around in STEIM Studio 3 in a soundfield as if I was crossing the street in China, an effect that I only know from my own recordings when I am wearing earphones. Magical.
How exciting, new and different working with all sort of loudspeakers is has become clear to me in my STEIM period. The knowledge and experience that I have gained in the 30 years I made soundworks for earphones has seemingly become obsolete.
Now I am investigating in a studio how I can create a reality. I place audio files not after one another, but next or opposite to one another. I am constructing an environment, which does not excist yet: soundfile for soundfile and speaker for speaker.
Besides the OMNIWAVE system I use mini speakers with ‘local ‘ reach, so that I can create a dialogue between the spacial sound field and isles of contrasting or additional sound.
New for me.
I work with a sound chart which holds 24 tracks, of which I use multiple tracks at any one time, and play with mono stereo omni, with volumes and sound colours.
The choices I can and eventually have to make out of a hundred hours of sound are endless. There are no laws for it. So it is just tossing with speakers (except the Omnis). Per the chosen audio file checking out the variety of speakers, and then listening to how everything sounds, alone or together. Listening to what is happening, what it evokes. A giga search.
In a log I am keeping up with what I have done on one day, what worked and did not work. Which combinations of sounds and speakers I still want to try. And I have defined sound themes which are going to help with the definite selection and order.

There are advisors which support me. Sound designer Evelien van der Molen is teaching me more about my digital audio workstatio as well as how to create space in between the sound layers.
Robert Bosch Audio is giving particularly sound technical advise and is constructing the needed devices.
Collegue Justin Bennett comments more from the side of sonology.
Dramaturge Robert Steijn came with an important question: what are you trying to achieve, a documentary or an esthetic experience?
I am deliberating on that. And on the final presentationform. Has it a beginning and an end? Is it going to be a loop, or is it going to take hours and has the listener just have to see how long he/ she wants to stay in the studio?
In the meanwhile I have finished my first phase in the STEIM Studio and am working in my pop up ‘homestudio’, temporarely without the Omni’s. I have positioned myself in the centre of my living room and have organised around me a set up of fifteen (mini) speakers, lying on side tables or on top of a cupboard. On this way I investigate which sound is doing what in this colourful collection of sound sources.
Concluding my residency
From October 20, 2017, I will be back in STEIM Studio 3.
A public Pilot will conclude my residency (November 1-4 from 14:00 – 18:00). Hope to meet you there.
During THE STEIM ‘Open Days’ and during the Amsterdam Museum Night my studio will be open as well. Please check out the openings hours of the STEIM programs. And don’t forget to check out the current directions to STEIM because of road works all over the place!
