Ik presenteer u: the Mouthesizer!!!
With the Mouthesizer, a mini headmounted ccd camera tracks the shadow area inside the mouth using colour and intensity thresholding. Shape parameters extracted from the segmented region are mapped to MIDI control changes. This allows one to control audio effects, synthesizer parameters, or anything you like with movements of the mouth. The vision algorithm is stable because the mouth opening is not a surface: illumination variations do not have a large effect on the segmented area.

In the first two video clips the mouthesizer controls timbre parameters in two sequencer loops implemented on the Nord Mod virtual modular synthesizer (made by Clavia, Sweden). In the first clip, mouth width is mapped to resonance and mouth height to the cut-off frequency of a low-pass filter. The mapping is non-linear, as becomes evident when the tongue is brought into play. In the second clip the aspect ratio of the segmented area is used to control a morph between the vowel formant filters for the vowels [a], , [o]. The mapping is chosen to correspond with the actual acoustic shape to sound mapping in speech production. This gives the player an intuitive gesture to effect mapping which makes use of existing human capabilities for sound control. In the third video clip, jazz guitarist Ichiro Umata uses the mouthesizer to control wah-wah and distortion. The height of the mouth opening is mapped to the cutoff frequency of a low pass filter, so that opening and closing the mouth gives a wah-wah effect (voicing "ah" and opening and closing the mouth has a similar acoustic effect). Mouth width is mapped to distortion: stretching the corners of the mouth wide in an emotional grimace produces a gritty, distorted sound. Like a foot pedal, the mouthesizer offers an additional controller to a musician who has both hands busy with a musical instrument. Our studies suggest that the mouth controller is more intuitive and easier to learn than a foot pedal.

Many people have asked me where they can buy a mouthesizer. Unfortunately, the mouthesizer is not yet commercially available. If you are serious about building your own, please feel free to get in touch by e-mail.

Die van China komt zelfs in deze eigenste thread al voor :confused:


(ik heb hem nochthans van hier gedownloaded) . Ik heb hem hier wel op m'n harddisk staan, maar ik weet niet hoe ik hem bij jou kan krijgen (2.8 Mb groot).

Ja, tuurlijk, sorry. Na een tijdje lees je niet elke keer de eerste post meer (jij wel?
Ik zal ook eens kijken of ik de clip van Emerson die zijn orgel neersteekt (voor zijn orgelpunt) kan vinden; die past hier wel bij, denk ik.
