# A python script to do both listening and talking. This is the basic model
|
|
# for an audio-only mumble client.
|
|
|
|
# Usage:
|
|
|
|
# Install pyaudio (instructions: https://people.csail.mit.edu/hubert/pyaudio/#downloads)
|
|
# If `fatal error: 'portaudio.h' file not found` is encountered while installing
|
|
# pyaudio even after following the instruction, this solution might be of help:
|
|
# https://stackoverflow.com/questions/33513522/when-installing-pyaudio-pip-cannot-find-portaudio-h-in-usr-local-include
|
|
#
|
|
# Install dependencies for pymumble.
|
|
#
|
|
# Set up a mumber server. For testing purpose, you can use https://guildbit.com/
|
|
# to spin up a free server. Hard code the server details in this file.
|
|
#
|
|
# run `python3 ./listen_n_talk.py`. Now an audio-only mumble client is connected
|
|
# to the server.
|
|
#
|
|
# To test its functionality, in a separate device, use some official mumble
|
|
# client (https://www.mumble.com/mumble-download.php) to verbally communicate
|
|
# with this audio-only client.
|
|
#
|
|
# Works on MacOS. Does NOT work on RPi 3B+ (I cannot figure out why. Help will
|
|
# be much appreciated)
