Hi!

I am TOTALLY new in ROS. I have a package consisting of two ROS modules where the first module takes input from a microphone and saves it as a ".wav" file. I want this module to publish this ".wav"-file to a topic so that the other ROS module is able to receive it(subscribe the topic). How do I do this? I have been looking at the ROS package called audio_common, but I cant figure out how to do it. Do I need to convert the ".wav"-file into bytes and stuff before sending? I have no idea!

Any advices would help here!

Hi!

I have a problem passing arguments to a callback function when Subscribing a ROStopic. The code below is what I do have now. But I only received error messages when I tried to pass arguments to the callback function. I want to send two dictionaries to the callback function together with the text received on the topic called "text" in the subscriber function below. How to pass these arguments? So far I have only been receiving thousands of error messages.

def callback(data):
    rospy.loginfo(data)

def subscriber():
    rospy.init_node("listen_for_conversation",anonymous=True)
    dict_1 = {.....}
    dict_2={......}
    content = rospy.Subscriber("text",String,callback)
    rospy.spin()

Hoping for good answers!

Thanks
