send udp directly from music player w/o microphone #210

Open aamarioneta opened 5 years ago

aamarioneta commented 5 years ago

is it possible to send udp data directly from the player to the nodemcu without the need of a microphone?

Advantages: less noise, more accurate, less delay

i play music with kodi. following possibilities come to mind:

Scott is in the process of a rewrite that will allow nodejs plugins to be released at a future date. In the mean time what platform are you on?

aamarioneta commented 5 years ago

Ubuntu 14.04, will probably upgrade soon.

There’s a few issues on here similar to yours I believe, you’re trying to get the audio playing on your device to stream directly to the arduino, rather than sampling from the mic and sending correct? If so I know on windows you can use the stereo mixer and I believe we figured out a solution for Linux previously I’ll have a look at the previous issues and see if I can find it.

Yes, thats exactly what i want. However the stream has to be in format [i,r,g,b] if i understand the .ino code correctly. It also has to be calculated for the exact number of pixels. That means the raw audio stream has to be processed before it is streamed. Otherwise the processing has to be done on the esp8266. I dont know. Is it powerful enough?

I think some of the fft would be a bit to much for something like the esp8266 to handle, so the processing would have to still be done on the computer but implementing loopback does decrease the delay and increase the overall quality of the animation in my experience
