audio sender
Closed this issue · 5 comments
would it be possible to also send audio with NDI or just receive it?
do you happen to have some tips on how to implement this?
thanks a bunch
I added an audio example.
There's also a receiver example.
check it, please. :)
thanks for making those examples.
I tried them. I tried both on the same computer which produces crackling noisy sound.
Then I tired is with 2 computers on the same local network. Same problem with crackling bad sound.
receiver does seem to start ok
NDI Source Detected : STEPHAN.LOCAL (ofxNDI audio sender example),10.0.1.3:5961
but after a while says:
[warning] ofRtAudioSoundStream: stream over/underflow detected
does it work for you?
I'm on macOS 10.12.6 with OF 0.10.0
No, my machine also makes noise. XD
The noise occurs because there is no enough received audio samples when the system requires audio signal.
I thought it was okay because it is not a problem from the addon itself; it depends how programmers treat their audio buffers.
It is related to a kind of tradeoff between responsibility and stability.
But after some glance and checking, now I think at least I should show how developers could deal with them.
I roughly fixed audio examples to try to show the way.
Could you try it out?

After more fixes and optimization, I will merge them to master.
thanks for putting in this extra work.
yes it does work better now. the audio makes sense now. it's still very low quality over my wifi network with some crackling too.
But you are correct that's up to me now to figure out how to make the send and receive buffer more stable.
I was hoping that NDI is this magic tool that handles most of the quality control in the back :(
Updated examples and closing this issue.

Actually me too. 😢
