All-purpose auto-record. Made this project using a Raspberry Pi (or a similar device) and a usb-mic to record an acoustic piano.

Description

This is a Python script that can be run as a Unix service on any linux-based platform. The script connects to a usb-microphone and keeps listening to it's input. If the input goes above a certain loudness level, it starts recording. Once it encounters a silence (audio signal below the threshold) for 5 seconds, it stops recording and saves the file — either locally or on Google Drive.

I made this script to run on a Raspberry Pi 4, using a Zoom H1N USB Recorder — which is placed inside my Kawai Upright Piano. Whenever the piano is played, the script saves the audio clip to a Google Drive folder automatically.

As a result, I never have to worry about pressing record while playing.

Installation

You are going to need Python 3 on your system. See how to install python on your machine.

Clone the repository to your local machine and navigate to the cloned repository.

git clone { repo URL }
cd auto-record

Install the required python packages.

python3 -m pip install -r requirements.txt

To configure the parameters for the app, open config.yml in an editor.

- threshold: 100
- lol: something

Try running the script now.

python3 record.py

You will see the following output —

(Optional) Run the script as a UNIX service

Run this on the Terminal:

chmod +x install_service.sh
./install_service.sh

To remove the service,
