pulseaudio-stream-fader

PulseAudio stream fader. Automatically fades-pauses/unpauses-fades streams based upon user rules.

Installation

Just symlink the script to wherever is convenient (~/bin or /usr/local/bin), do a "chmod +x" on it, run. Example: ln -s $(pwd)/pulseaudio-stream-fader.py /usr/local/bin/pulseaudio-stream-fader

Make sure you have load-module module-dbus-protocol line in /etc/pulse/default.pa (or /etc/pulse/system.pa, if system-wide daemon is used), especially on Ubuntu, where it seem to be disabled by default.

Requirements

Python 3
dbus-python
PyGObject
PulseAudio 1.0+

Usage

Run the script. There's no configuration yet, pulseaudio-stream-fader listens to chrome/chromium stream events and pauses/unpauses spotify.

Bugs

Chromium may start a stream if google search results contain word definition. Long term solution would be to monitor stream VU levels.

Loosely based upon pulseaudio-mixer-cli.
