Various experiments in the lab at Hideaway Studio to listen in and explore a secret world of reflected and modulated light in the audio-frequency domain from various sources in everyday life.

Literally listening to shadows, no microphones were used to make any of these recordings - they were entirely made using light sources and analog high-gain photo-sensors.  I've dubbed this new technique The Optical Microphone...

The Optical Microphone... (Optically Generated Audio Experiments)

Optically reflected sound from the grooves of an 70 year old classical music 78rpm shellac record... 

Recorded over at least 10 grooves at a time using an analog optical sensor resulting in a bizarre ghostly droning effect.  The optical sensor was fixed to a surface some distance from the record to capture the modulated reflections.  It took a great deal of concentration to position the light source by hand at the correct angle to catch the inside of the groove and reflect it towards the light sensor whilst moving it slowly across the surface of the record!  To be honest, I was truly amazed it worked this well.

Sound of Reflected Light From An Old 78 Record... (Optical Sound Experiment)

The sound created by shining a flashlight through the neck of a miniature kitchen sand timer and picking up the modulated light on the other side of the glass with a photo sensor.  At the end of the recording you can hear the individual grains of sand landing as the timer empties resulting in something that sounds 100 times its size.  If you put this thing to your ear you cannot hear anything at all!

NB: It gets louder and more "grainy" towards the end as the sand level gets higher and closer to the point the light was aimed at.

Sound of Light Through A Tiny Sand Timer (Optical Sound Experiment)

Made by splashing water creating ripples in a pan whilst shining a bright light onto it and directly receiving the resulting audio frequency domain modulated reflected light some distance away with a photo sensor as sound.  The resulting raw audio was overdubbed 4 times at different points into the recording and various pan positions to create a pseudo-stereo effect. More sound from light recordings here:

Sound of Light Reflected From Water Ripples (Optical Sound Experiment)

This is what happens if you place a Picardie tumbler upside down on a turntable, shine a light at it, and pickup the resulting reflected light with a photo sensor :)

I found by carefully moving the position of the light and the sensor it was possible to "perform" the chopper fly-by effect with all manner of interesting sonic artefacts coming out in the process thanks to the imperfections in the glass.

Sound of Light Reflected From Rotating Picardie Glass (Optical Sound Experiment)

This was not recorded with a microphone but made by shining a light through a glass beaker full of water whilst dropping an effervescent Vitamin-C tablet into it and recording the modulated light on the far side of the beaker with a photo sensor whilst it dissolved.  Multiple takes were recorded and layered together at various pan positions to create a pseudo stereo effect.

Sound of Light Thru Effervescent Vit-C Tablet... (Optical Sound)

A segue of recordings played back at normal, twice and half speed of the sound of laser light being modulated by plumes of dust kicked up by dropping nuts and bolts into dry icing sugar in a large glass jar. The optical mic was positioned on the far side of the jar and sometimes you can just make out the glass walls pinging as the bolts land on the bottom of the jar.

The slowly building up vortex was made by swirling the icing sugar and then playing back the resulting return to still  air in reverse.

Rather like the oil in water and electrolysis experiments, since it all takes time to disperse, you get a kind of natural decay tail effect.

D.A.Wilson is an Electronic Engineer, Sound Designer & Vintage Synth Specialist with a particular interest in combining vintage tube, classic analog and modern digital technologies working as a synth engineer looking after a very considerable amount of vintage studio equipment for Will Gregory (Goldfrapp / Moog Ensemble) and a number of other internationally celebrated electronic musicians and producers.  Having undertaken several major restorations and produced custom electronic designs for a number of major artists including Jean-Michel Jarre, Dani is also known for fully restoring two out of the world's four remaining 1979 Crumar GDS and partially restoring 1938 Novachord 346 (the only known operational Novachord in the UK) to playable order along with developing and producing the new Elfin family of 8-bit polysynths and the popular MIDI Front Panel Animator (FPA), Filter Defeat Module (FDM) and XD-280 Drive Emulator upgrades for the AKAI S612 sampler.
