I saw that some applications like the Wekinator use OSC blobs for streaming audio.
So I tried something similar with JUCE and found that blob data are not sent with a block size above 4076 bytes (on my machine - this value could of course differ on other machines/OSes).
Tested with JUCE 4.3.0 and /develop branch.
Debugging into OSC send showed nothing that is obviously failing inside JUCE, so it might be something happening asynchronous (side not: found that it might be a bit risky that OSCSender::Pimpl.send does not check for the return value of outStream.writeMessage (message); - but in my case it is true).
I filed an issue with reproducible test case for this.
Did anyone experience this before?
