About

One-button recording, without any devices besides Raspberry with Pisound needed.

Core

• recording.sh: Wrapper for Pisound Button
  • Handles starting and stopping of recording
  • Blinks the led during recording
• recording.service: SystemD unit for recording
  • Dependency for external shares, needs to be adapted
  • Entire recording logic
  • Current date in filename, formatted as 2022-02-06_19-58-55.mp3

Optional

• /etc/fstab:
  • Definition of mount point used in recording.service, via webdav (davfs) in my case
  • https://<webdav-url> /srv/share davfs user,rw,auto,_netdev,nofail 0 0
• /etc/davfs/secrets:
  • davfs credentials for non-interactive mount
  • https://<webdav-url> <username> <password>
• /etc/pisound.conf:
  • Button click configuration, for example
  • CLICK_1 /usr/local/pisound/scripts/pisound-btn/recording.sh

Usage

• Create share directory with mkdir /srv/share

• Test mount with mount /srv/share

• Install (see below)

• Press button to start recording, led starts blinking

• Press button to stop recording, blinking intensivies during convert and upload and stops when done

• On the console the commands systemctl start recording.service and systemctl stop recording.service can be used respectively instead of pressing the button.
