 icesound — play audio files when interesting GUI events happen

Synopsis

icesound [Options]

Description

The icewm(1) window manager generates so-called GUI events in response to interesting actions, like opening or closing of application windows, switching of work space, etc.  GUI events are a property of the X root window.  icewm(1) changes this property whenever a new GUI event occurs.  Interested applications can listen for changes to this property.  There are nearly twenty GUI events defined.

icesound is an application, which is one of the icewm(1) applications, which responds to these GUI events by playing audio files. These sound files are .wav files located in a sounds sub-directory in one of the icewm(1) configuration directories.

icesound supports several common audio interfaces.  These are: ALSA, OSS and libAO.  These must be enabled during configuration. ALSA, OSS and libAO all require support for libsndfile, which is a very common library to read audio files.

ALSA

ALSA is rather involved to program and it works, but this could use more testing.  It plays at most one sound at a time.

LibAO

LibAO is a cross-platform audio output library which is a convenient wrapper around a significant number of common audio interfaces.  It has a simple configuration file which is documented in the libao.conf(5) manual page.

OSS

The Open Sound System (OSS) is a cross-platform sound interface, which is fully supported by icesound.

When multiple audio interfaces are available icesound will examine them all until it finds one which it can connect to and then use that one. By default it prefers them in the order of: AO, ALSA, OSS.
