12.219 soundscape

Soundscapes https://en.wikipedia.org/wiki/Soundscape define an acoustic environment. Boodler at http://boodler.org is a Python-based SoundScape generator. To use this module, first install boodler. Then install the soundscape packages (*.boop) files available at http://boodler.org/lib. Make sure boodler works and produces audio in your environment. finally install the Boodler packages from emacspeak/scapes from the Emacspeak GitHub repository by running cd emacspeak/scapes; make

When boodler is set up and all packages installed, copy file emacspeak/scapes/soundscapes to ~/.boodler/Collection. The above file lists all installed SoundScapes. Directory emacspeak/scapes also contains additional Boodler Agents and SoundScapes that I have created for use with Emacspeak.

Module soundscape.el defines Emacs conveniences for running Soundscapes. Main Entry Points:

• M-x soundscape-toggle – Enables or disables automatic SoundScapes.
• M-x soundscape – runs a named SoundScape
• M-x soundscape-stop – Stops a specified running Soundscape.
• M-x soundscape-kill – Kills all running Soundscapes.

When automatic Soundscapes are enabled, SoundScapes are started and stopped based on the current major mode. Active Soundscape are displayed as part of the minor-mode-alist. Command emacspeak-speak-minor-mode-line can be used to have this spoken.

Thus, SoundScapes can be thought of as reflecting the mood of the current mode. This package defines a single soundscape-default-theme that is loaded using (soundscape-load soundscape-default-theme). Emacs modes that provide similar functionality e.g., communication == email, IM, ... map to the same mood.
