Ache
When you were at home growing up, each day felt so long. Now that you’re grown and on your own, it feels like it never lasted long enough.
Pseudohuasca
pseudohuasca creates videos clips that have odd glitchy entities and highly clipped electronic audio sounds. It made me think of what the anomalies in the book Roadside Picnic might look like.
Angine de Poitrine
This French band has been making waves online. They’re not only dressed in some of the most bizarre outfits, they also consist of a microtonal bassist and a drummer.
The Prince’s what??
What in the world did I just listen too?? This was made in 1969.
Getting ready to believe
This song is amazing – and perfect for Easter.
Polyrhythms
Musical language – Speak what you play
I had no idea with tabla playing, how you say it is how you play it.
Emulating audio IC’s – from scanning the chip with a microscope
Giulioz gives a sequel to last year’s talk “Proprietary silicon ICs and dubious marketing claims? Let’s fight those with a microscope!“, where he showed how he reverse engineered a pretty old device by looking at microscope silicon pics alone, with manual tracing and some custom tools.
Fast forward, he shows how he reverse engineered a much modern chip: the custom Roland/Toshiba TC170C140 ESP chip (1995). Completing this task required a different approach, as doing it manually would have required too much time. He used a guided, automated approach that combines clever microscopy with computer vision to automatically classify standard cells in the chip, saving us most of the manual work.
They then sped things up even further by directly probing the chip: by exploiting test routines and sending random data to the chip he figured out how the internal registers worked to create a bit-accurate emulator. He even gives the source code out on github so you can emulate the devices yourself.
Listen to the result at 32:19 where they play Darude Sandstorm.

Psychoacoustics
Binaural beats, tritone paradox, pitch and tempo circularity, wason effect for faking high performance audio, biological audio effects, and using missing fundamentals for playback on phones and low-quality devices? Casey Connor demonstrates some fascinating audio effects and illusions in his multi-part series of audio illusions and effects. Some of them are used to simulate high performance playback on cheap devices like phones. Good headphones are required for some of them.
Here’s the first video go get you started:
Jump Around origins
Where’s that distinctive backbeat come from in the song Jump Around by House of Pain? Samples of Motown of course…
