Creating interactive systems specialised in generating sound/music based on algorithms or reacting to movement, scenery, color, etc.

Could be applied to any purpose such as academic research, education, art therapy, stage effects, game, ads or whatever. Flexibly available to be modified according to what you need.


Listening to Movement

A camera detects movement and transforms it into sound. It makes sound only when something is moving, and the pitch and volume depend on how fast it moves. It is a good idea to use it for dance which enables the dancer to adapt sound/music for a dance - the opposite of common ways. You do not need anyone to play sound/music as the system runs automatically.


Listening to Scenery / Light

A camera detects objects and transforms them into sound. It makes sound only when there is/are object(s), and the tone and volume depend on color and brightness of every object. The bigger the object is, the lower the sound becomes. It is a good idea to use it for the scenery seen from a train/vehicle window or a boat traveling on a river.


Audible Virtual Biosphere

Binaryosphere is a software that emulates "nature (an ecosystem)" - sound of rain, wind, waves, waterfall, thunder, and imaginary creatures reacting to the movement of people as well as according to time, temperature, humidity of the day, and seasons - which means the sound will be always different, just like real nature.

It runs anywhere there is a macOS or Windows computer with speakers and a camera(s) connected. At your shop, school, office, on stage, home - wherever you want. Every sound is generated by internal synthesizers and no recording is used.


Physical-activated Step Sequencer

Miohata is a software that turns something such as a wall or a table into an instrument. By recording a sound of any object around you and placing it on a cell of a table, Miohata recognises the object and starts making sound as a light belt comes along with the sound you have just recorded. Miohata has several tracks that can deal with different sounds at different times.

The word "Miohata" stands for "320" in traditional Japanese math - there are 320 cells consist of 2 bars of 16 beats when divided by 10 tracks. It runs anywhere there is a wall or table, and a macOS or Windows computer with speakers and a camera(s) connected. At your shop, school, office, on stage, home - wherever you want.


Acoustic Simulator for Disaster Warning System


This is a software aimed at training disaster warning announcement which reproduces what listeners (people evacuating) actually hear by simulating speaker properties, decay, reflection, ambience, and being indoors.

There are disaster warning systems for each local area in Japan, which does not really reach the inhabitants sometimes because of being far away from the speaker, being indoors, lots of reflections caused by buildings and mountains, and some noise such as rain or construction works. But it is known that changing the way the announcer speaks will improve conveying more accurate information and save more lives from disaster. To make it possible, the first thing is to know how the inhabitants actually hear the announcer's voice, which the simulator is aiming for.

  • Choose and play a background soundscape (rain, construction works, etc.)
  • Choose and play a single tone (chime, etc.)
  • Play a siren
  • Choose and play announcement recording
  • Record and play announcement
  • Set a frequency property of a simulated speaker
  • Set a baseline of decay simulation (distance from the speaker [m] and sound pressure level [dB SPL])
  • Simulate delay of direct sound from the speaker to the listener
  • Simulate reflection and delay caused by buildings or terrains (5 paths)
  • Simulate sound while being indoors (JIS A 4706 T-1 class transmission loss)
This system was presented in the following conference.

This system is based on the PureData patch published in the following documents, requested from Kanazawa Institute of Technology. (Japanese)

Q What is the "system" exactly?

A I mean a core software itself. When camera(s), speaker(s), or sensor(s) are used, they are considered to be a part of the "system".
Q Who is it for?

A It is for almost everyone who needs the system such as a school teacher who is looking for a new way to teach math or science (and of course music) using sound, a dancer who needs virtual musicians for his/her performance, a restaurant manager who is trying to attract some interest by interactive music reacting to weather and season, a solo musician who needs obedient players to perform songs with - and a lot more.
Q Will you make international deals?

A Yes. In that case, we need to contact each other completely online and you will need to setup system(s) yourself. Total dues can be variable according to tax conditions.
Q Is it easy to use?

A If you are able to send email with a computer, yes. The system will be simplified and works just like a software when it is passed to you.
Q What software do you use to make the system?

A Cycling '74 Max.
