I guess this is just an IoT-infested home but more immediate. Don't have to collect data with an always-listening gadget to display "relevant" ads on websites, just cut out all the stuff in the middle.

very bad idea, paranoid shouting 

@owl shut up Owl!!! Don't give them ideas!!! They are already coming!!! March 2022!!!!

@schratze @owl thanks, I hate this

@g1comics @schratze @owl

what worries me is that folk might even accept stuff like this, it reminds me of how in East Germany those lucky enough to get a fairly modern telephone (that relayed the whole room audio to a monitoring centre) did not simply unplug it or use a standalone bell to avoid being surveilled due to FOMO (or maybe the Stasi got suspicious if there /wasn't/ any audio)

@schratze @g1comics @owl

also worked with western telephones, but would have only been feasible when the set was hardwired as the terminal to get the audio wasn't presented on the phone plug and socket (it did occasionally get used by Special Branch, MI5 etc in the 1960s and 1970s)

during the 1980s the anarchist bookshop did have a telephone, which when it wasn't in use they always put next to a radio cassette recorder blaring music - this is why...

@vfrmedia @schratze @g1comics @owl nowadays that sadly wouldn't work, because they'd be able to filter out the music and hear the speech behind it

and the only way to not be eavesdropped would be in a faraday caged bunker without any electricity and using only sign language (until they find a method to interpret sign language from nanuscule air pressure changes through 30 cm thick concrete walls. shouldn't be too long until that, i'm afraid...)

@Stoori @vfrmedia @schratze @g1comics @owl But by definition some level of noise will be "unfilterable", the sampling precision is finite. The question is, is that noise unbearable to be in the vicinity of? Obviously you'd place the noise source next to the phone, so inverse-square would protect other people a bit. Anybody know what would be needed? Perhaps loads and loads of recordings of human voices? (Vloggers to the rescue!) Any audio engineers here?

@Steinar @Stoori @schratze @g1comics @owl

I've worked as an AV/broadcast engineer over the years and it would be relatively hard to filter out the speech using 1980s analogue tech; but a recording can be processed with DSP.

consider also that modern mobile telephones and smartspeakers have more than one microphone and do noise cancelling to pick up the speech; otherwise they wouldn't work with voice commands to turn down the volume of music they are playing >>

@Steinar @Stoori @schratze @g1comics @owl

the difference over the decades is the analogue telephone was intended only as a telephone for low quality audio communications and funded for such, any surveillance capability was a "bonus" to those who wanted to make use of it.

Smartspeakers, mobile telephones etc are designed from the start as higher quality audio processing devices and part funded by the perceived value of the data they gather on their users..

@vfrmedia @Stoori @schratze @g1comics @owl So it's a much more difficult problem than before, on the other hand, we can afford ourselves dedicated counter-devices. Multiple sensors? Put the phone in box with multiple mounted speakers. High fidelity sensor? We have high fidelity noise and sound sources too. What happens if the phone is dropped in bowl of water (with extra waterproofing as needed) and you start a mixer in the water next to it? I am honestly asking here.

@Steinar @vfrmedia @schratze @g1comics @owl we need a test lab for these

@Stoori @Steinar @schratze @g1comics @owl

putting the phone a box that played music or other noise would make it difficult to monitor voices from it.

But it creates same dilemma the East Germans had; even if the box were transparent the enduser would have to watch it constantly to avoid missing notifications/telephone calls (making the device less useful!)

defeating audio surveillance 

@vfrmedia @Steinar @schratze @g1comics @owl i guess it would be pretty simple to have a blinking light on that box to announce calls and notifications

defeating audio surveillance 

@Stoori @vfrmedia @schratze @g1comics @owl Could even do some lovely overengineering and add a light sensor to react to the phone's notification LED and then play a sound based on that. The irony of it all would certainly be delicious. :) I have my own phone pretty much constantly on silent anyway.

@Steinar @Stoori @schratze @g1comics @owl

incidentally I routinely use two mobile phones, one as an LTE modem for my satnav traffic alerts (otherwise the phone audio is routed through the satnav which I don't want), I noticed that Google doesn't seem to be interested as much in the data from lower value (<100€) phones...

@owl my adartment is its own atblocker

re: very bad idea 

@owl oh no

now I’m seeing it, AmazonBasics Five-Over-Ones with Special Offers

very bad idea 

@owl Don’t give them any idea :blob_cat_oh_no:.

very bad idea 

@owl
I hope you're writing storyboards for Black Mirror and that you're not the head of innovation department at Google or Facebook.
Anyway, with apartments getting more and more expensive I fear it's just a matter of time until this becomes reality

very bad idea 

@Cyb3rVix3n I'm just an owl who does none of those things, fortunately
