Can someone show a short example how to run this from Python? I want to use this from Python script - function send and recv respectivelly ?

from amodem import config from amodem import audio from amodem import main

configuaration = config.Configuration() interface = audio.Interface(configuration) audio_library = "../../libportaudio64bit.dll" interface.load(audio_library)

src =

dst =

main.send(config, src, dst, gain=1.0, extra_silence=0.0)

Managed to call main.send function from Python script when saving to file, but couldn't get to work it when there is no output -o specified. The problem is how to specify dst variable when sending data without output ? What to give as an argument for FileType('wb', interface_factory)() ?

I can't understand how to use this with a personalized app. I will try debug to discover and maybe create a simple methods to send and receive data like a python socket

Running from Python script! #48
