This is an experimental live stream, with sounds from the inside of my compost pile. I’ve been wanting to try this for a while and it seems to work: https://aporee.org:8443/mobilemic18

Liuks! Just kept thinking about it and you did!

Yes, I used a recorder as a preamp and sent the output from the headphones to the pi zero

like!

Nice.

Amazing to listen to the constant movement and occasionally hearing some munching sounds.

super nice to be able to listen to this details!

It reminds a bit of the cavitation sounds of trees which are under hydric stress (only able to hear in the ultra sound range).

Wow! I want to try that, love it

Yes, lots of movement sounds but also what sounds like distinct munching. And there is even something that sounds like twitching or stridulation?

guess at the moment there are some critters in direct contact with the piezo microphone.

A first run of my new stream setup after the locusons image stopped working some time ago, thanks Udo for setting it up last night! An unspectacular listening perspective from the third floor with direct ›view‹ of Landwehrkanal in Kreuzberg. Especially nice is the wide hearing range of several 100 m for car horns and around 100 m for birds, clings and clongs and voices passing by under my window. And there are hissy roof works going on above me, in total a rather transparent and calm city mix.

listening all moring, it's extremely calming

Oh I should have added the stream URL, here it is: http://locus.creacast.com:9001/berlin_kanalworx.mp3

Very true and goes nicely together with digesting after breakfast ;.)

Wah, I find it wildly amazing, but also disconcerting, associations about graves and rotting bodies flooding my mind, wooh

i'm hearing transformation and metamorphosis, a change of form.

i feel this as a connection between me and everything else, the ongoing processes within and outside of our bodies . it can feel unsettling but the connecting is somehow stronger for me here

Listening to the compost heap and the Berlin soundscape together makes an interesting juxtaposition - as said earlier the micro molecular is driving the macro.

I’ve been listening a lot too and also find it calming. The small micro-variations reveal a process; earthly digestion, transformation, soil creation… it was dark when I placed the mics so I have no visual account of what is happening inside the heap.

some singing worms just came by. It reminds me of listening to ant heaps and maggots + piezos, but I never heard a compost heap like this. I recently read (can't remember where) that soil scientists use hydrophones to check soil quality - more sound = more worms = good soil.

Yes, I think Marcus Maeder did research on this.
Really interesting stream, John! The similarities between our guts after a meal and the fermenting and composting organic material! It let's me think that I'm also a walking compost pile

Yes, I have seen different ‘soil listening’ projects around. One researcher in Switzerland dveloped a special microphone device with a long needle. I’m using basic piezos so all the sounds come from close physical proximity, but I also thought I heard some type of vocalisation… curious

so, who is going to swallow a mobile mic?

micro-biome symphony

had to remember martin howses worm projects a while back - http://1010.co.uk/org/worms.html

Vocalisations again. the first ones were birds but then?

Wow John Just listening in to the compost stream, it’s sounds kind of comforting …the munching away. Are you planning on leaving it up for a while? I would love to keep coming back to this.

Until the batteries run out… but I can also try to run it more permanently

recently in a lecture maeder spoke about this, i think he mentioned larvae

ok

while ago I've spent a day together with Marcus Mäder listening to heavily polluted ground/soil at a former Luxembourg steel plant. That was inspiring, so I've experimented a bit with modified contact mics. This rather simple design produced quite nice results. It's simply a copper wire soldered to piezo plates. Here are 2 recordings made with these, at Prinzessinnen Garten Berlin: https://aporee.org/maps/?loc=56886&snd=65066 and another one in a tiny slot between cobble stones at Admiralsbrücke: https://aporee.org/maps/?loc=62072&snd=71425

Prety & interesting sounds John a pleasure to here the active decay at your place!

Something for Stelarc

Concerning soil listening, Swiss "Elekon" known for their bat detectors, makes soil listening device Allsounder Aliso. This is some kind of AudioMoth for soil listening, programmable, controlled vy phone app. Reminds me exoensive version of AudioMoth. Also they sell soil probe sensor separately which I use with normal piezo buffer/preamp. https://www.elekon.ch/website/shop/shop/#!/ALLSOUNDER-ALISO/p/538485078/category=144480292
