Uploading in bokeh

how can I upload a signal through a web page and then plot it, is bokeh can do that?

@Yasien99 The short answer “yes”. A longer answer would require that you provide much more detail about what exactly you are hoping to accomplish.

I am trying to make real-time signal processing and I want to upload wav file to my website and then plot it and make a bunch of filters on the signal

Bokeh has a FileInput widget that can let users upload the contents of a file. Then your Bokeh server app code can do whatever you want with the .wav data (process it, transform it, plot it, etc).
