loudometer is an audio input monitor that triggers a web request when it detects noise.
Depends on pip install pyaudio.
This project was made to send commands to Bitfocus Companion, to switch camera views on a video stream depending on the loudness of the audio input. The input in this instance came from a RODEcaster Pro, presenting to the OS as a single 14-channel audio source. It can be used to trigger HTTP requests to any web address.
loudometer.py will let you select an audio stream source, and will monitor the volume levels of each channel in that stream.
The first time you run the program it will generate a template config file config.json and then exit. Configure the input_device_name (if you know it), and enter web URLs to target when a channel gets hot. An empty string means do nothing.
The configuration file will be reloaded as the program runs.
To test if PyAudio is working and installed correctly, and to see a list of available input devices, run the test_pyaudio.py script.
Further instructions and tips are available in instructions.txt.
Commands can be sent to this program via UDP. The default port is 36591. This feature can be disabled by setting udp_commands to false.
There are currently only two commands. ARM and DISARM, which will arm and disarm all loudness triggers. Instructions for setting this in Bitfocus Companion have been added to instructions.txt.
