The static is the space between transmissions. Ghosts of previous broadcasts play at intervals.

Trying a test broadcast right now. The broadcast shows up on the spectrum, but it only plays a short snippet of sound, with quite degraded quality. As a listener, changing the frequency then coming back grabs another, more recent snippet of sound.
Am I missing something or is something wrong? Can someone confirm the symptoms?
(Broadcasting with BUTT on MacOS, I tried listening through several devices: MacOS, Android, iOS, same symptoms)
Edit: I suspect it was picking sound up from my microphone, which was definitely not the intent :s Will give it a try later again.

I transmitted for about half an hour last night.
Was a fun experience, jamming on something in Ableton.
Used Rogue Amoeba Loopback to create a virtual input/output, and selected that as the output in Ableton and the input in BUTT.
To those above saying they couldn’t figure out how to listen because they were only hearing static: there was probably just no one broadcasting. I was the only one during the time I did.
Thanks @nullband, really fun idea, and it then sent me down a rabbit hole looking for SW transmissions on the Internet. Couldn’t find much except for static. This site shows a map of known SW antennas connected to the internet: rx.linkfanel.net
I remembered from the SOMA MESSEIVER thread that the best chance to pick up SW is in remote areas, so I went to the Reunion Island one, and actually found some music! Sounded like East African music to my uneducated ear.
I also found this recording on YouTube of a ‘numbers station’ that has been transmitting intermittently since the USA/Israel attacks on Iran started a month ago.

Thank you ! Glad to hear it worked and you were able to figure out how to connect.
Transmitting and listening on the same device can be tricky if you can’t create a loop back without separating your output.
I use KiwiSDR for any SW radio listening.
Plenty of transmitters to choose from.

Your transmission was definitely an odd one in the system.
I can see it I assume.
Here it says it is 9 mins long but it also says it’s 550mb
Which would work out to be approx 9-10 hours
So icecast has had a bit of glitch.

Yeah, I ended up listening on my phone just to be sure there is actually music being transmitted.
I initially transmitted silence (possibly my mic) because I hadn’t selected the correct input in BUTT. I could see the red vertical line on nullband but wasn’t sure if I was hearing the music from ableton or nullband.
When I checked on my phone it turned out it was just silence. I then made sure Loopback was selected in BUTT (it was earlier, but I think it got reset when I re-imorted the key/config). Changing that, and restarting the transmission I heard the music on my phone.
Another tip for people, if you stop the transmission you have to re-download a key. It is mentioned on nullband that keys are single use, but it might be easy to forget when you restart a transmission that you need to download a new key first. BUTT will display a message that login to the server failed or something to that effect.

I use Blackhole, your explanation is great ! I appreciate it.
i missed the latest transmissions 
but there’s still something not clear to me
like others, i’m just getting noise regardless of the selected frequency, and that’s fine when it happens and there’s no one transmitting, so i’m assuming that in this case something has been/is being transmitted but no matter the selected frequency, i just get noise…

I think I caught some of this 
enjoyed it, put me in a bit of a trance. If it’s the broadcast I’m thinking of … I was listening to Radiohead then switched to that and the guitar was eerily similar
agreed:)

There is just random visual artefacts that come and go. Doesn’t necessarily mean there was a transmission.

Only vertical lines that reach top to bottom are transmissions

i might be getting this wrong but i’m not sure about ‘…qualifying broadcasts get processed and reappear later at a harmonic frequency…’
does it mean that the transmitted audio is stored somewhere before being transmitted/processed or? 
also, what’s the meaning of ‘qualifying broadcasts’? is there some sort of selection being made using an algorithm or something?
It gets replayed 24 hours later degraded through a processor.
I’m streaming now if you want to try and catch a transmission.

tuned in and listening 
so that means it is actually stored somewhere. what happens to the stream after the 24hours?
edit: sorry for all these questions, just curious
The server auto deletes

Giving it another try right now. Looks like sound is going through just fine

i like what i’m listening to right now…
@nullband: what about a little chat somewhere in the corner and maybe a counter of listeners? would it be something relatively easy to implement?
