  • Demonstration of a wave table for the Synthesis Technology E352 based on observations of the variable star RR Lyrae by the Kepler space telescope. These wave tables are available in the SynthTech WaveEdit repository.
    NOTE: there are rather terrible compression artifacts in the audio, particularly in the first section. Listen to the uncompressed audio file here: stevepur.com/mu...
    RR Lyrae (en.wikipedia.o...) varies in brightness by over a factor of 2 every 13.5 hours or so, with a characteristic pattern of variation. This particular star is good for musical sounds because the oscillations don't exactly repeat. Using observations from different times together, like in the video, creates a rich variation in phase and texture.
    Details of these observations can be found at arxiv.org/pdf/...,
    arxiv.org/pdf/...,
    arxiv.org/pdf/... and arxiv.org/pdf/....
    Each wave table breaks up three months of observation into 64 waves, with each wave having about two periods of oscillation. Each three-month period is called a "quarter", and the waves shown in the video are for quarter 5 (Q5) and quarter 6 (Q6) of Kepler's observations.
    My thanks to Jon Jenkins for the code that I modified to make these wave tables.

    Whoa. With stereo earphones; this is great.

    that was just a saw wave for 5 minutes of my life

    Are these wavetables going to be available? Sounds lovely!

      Nevermind: They are in WaveEdit's download section. Thx!

      WaveEdit, see ST's website.

      can't seem to find it either. Can you post a link to these files? They are not on github nor on the ST website. I would be up to make a small contribution for your effort...

    What do the chaoticas modulate?

      CV X and CV Y, and probably a filter parameter or two.
