A simple app for recording audio, and playing a frequency when the volume in the room is over some threshold.
This app has many uses, but is made originally for training a dog to stop barking. By playing a high pitched loud sound whenever my computer detected high volume noise, I trained my dog to stop barking while I was gone.
It will also email you about events with recordings and summarize the events throughout the day.
You'll want to start by installing python and poetry on your system. Do this however you see fit.
# If you are on macosx, be sure to do this, otherwise skip
brew install portaudio
# On ubuntu you might need to do
sudo apt install portaudio19-dev
# Then just install the requirements with poetry
poetry install
# Then install pre-commit (only if you are contributing)
pre-commit install./run.sh
NOTE: Only tapping CTRL+C twice will stop the app using this script.
This will start the app and record audio from your default input device. When the volume is over the threshold, it will play a high pitched sound.
To send an email to yourself, you need to create a file called config.toml in the root of the project. It should look like this:
sender_email = ""
receiver_email = ""
smtp_server = ""
smtp_password = ""
smtp_port = 1234Do not share this as it contains your email password.
Optionally, you can exclude your password from this file and set it in your environment variables as DOGBARKING_SMTP_PASSWORD.
Now you need an smtp compatible email provider. I recommend https://www.mailgun.com/ as you can send to 5 authorized emails for free and it was easy to set up.
For mailgun your config.toml would look like this:
smtp_server = "smtp.mailgun.org"
smtp_port = 465
sender_email = "Mailgun Sandbox <postmaster@sandbox*.mailgun.org>" # Just an example
receiver_email = ""
smtp_password = ""
