Ambisonic / Soundfield Microphone.

I would love it even if it was completely useless.

gorgeous!

personally i learn a lot from people asking questions about images other people post…if they were private messages I wouldn’t learn anything, images is the ‘focus’ of this thread…and it remains so, but I think it would be a shame if we ‘banned’ people talking about those images. Starting a new thread seems a bit of an overcomplicated solution. If you don’t want to read the words it’s easy to scroll through just looking at the pictures, I often do that

Thank you for your input @dspk.
No one is talking about banning anyone.
I was merely suggesting that we include a topical picture with every post.
But perhaps that is too much to ask for.

and with that, to accompany Ambisonic microphone, I present to you the tape-head clock:

I agree, so long as the ratio of picture posts to text posts remains healthy we’re alright.

Anyways, here’s a photo from Cleveland Bridge I took the other day on my phone (just to help the ratio…). Even the non-Georgian bits of Bath are very pretty!

I agree wholeheartedly.

I am not in the position to post an actual picture (not at home) but want to ask about yours - this is beautiful, can you describe it? I would love to know more about its design and application.

Without being to wordy:

Ambisonics is a recording method which aims to preserve the spatial relationships in the sounds, so that the sound field can be recreated on an appropriate system (speaker array).

The microphone array decomposes the sound field into components known as spherical harmonics. These form an orthonormal set of basis functions which can describe functions present on the sphere (the incident sound field). Similar to how a fourier series can be used to reconstruct any time varying signal, the spherical harmonics are used to recreate the sound field.

There are existing microphones that accomplish this. The eigenmike is one. most have few sensors. This restricts the upper frequencies which it can record from spatial aliasing. The aim of this project was to get more sensors. I used 120 MEMS mircophones and an FPGA. The shape is a compromise, ideally it would be a sphere, but given the time constraints of the project I used an icosahedron made of PCBs. It’s roughly the size of a human head.

I probably owe you all a picture for this. debugging this thing was a bit of a nightmare…

Here is a pic to balance the ‘nerds with a gear complex’ trend on internet music forums. I rejoined Instagram and it’s amazing how a simple pleasure like hedgehogs and dachshunds brightens the day as I check my feed. This is Azuki https://www.instagram.com/hedgehog_azuki/

Spec’d for Pulp Logic but clearly installed in Intellijel cases. Wish I could get some…so I can put them in Intellijel cases.

He posted this today:

Meng Qi

That slim one in the middle has a titanium face plate. That, the wood, and the hex bolts, with of course all the CL stuff is just sublime.

Utterly aside from his electronics, circuits, and so forth, not enough credit is given to Meng Qi’s case/materials work. I’ve seen videos and snaps of his studio, but he must have some pretty good joinery and materials skills and facility hiding somewhere, given the speed with which he churns this beautiful stuff out. Working titanium is no joke…unless you have a plasma cutter!

was lucky enough to catch @hecanjog at cafe mustache in chicago tonight! heard pippi irl – really flexible sounds and his handling of the timing in each piece played was masterful. such a cool experience, really sweet dude.

finally made some progress

Waiting for my wall to get fixed.

A few years ago I got some custom converse made (they had a web app that you could customize all the colors/aspects of the shoe), and as part of that you can put your name or whatever on the side. Wanting to use that aspect of it, but in a different way, I got 12 "l"s (or it might have been capital "I"s), as this was the maximum character count.

I’ve always like the stark look of that, but today @Angela pointed out that these are my official Lines converse! (give or take a few "l"s)
