The &artsdsp; utility, <link linkend="artsdsp">described
|
||
|
|
previously</link>, allows most legacy sound applications that talk to
|
||
|
|
the audio devices directly, to work properly under &arts;. Applications
|
||
|
|
written to use the Enlightenment Sound Daemon
|
||
|
|
(<application>esd</application>) will also work in most cases by running
|
||
|
|
<application>esd</application> under &artsdsp;.

This makes a good short term solution to porting existing applications
|
||
|
|
to &kde;. However, it does not allow the application to directly take
|
||
|
|
advantage of all of the power of &arts;, such as using modules and
|
||
|
|
multimedia streams other than digital audio. If the application goes
|
||
|
|
beyond simple playing of sound files, it usually makes sense to add
|
||
|
|
native support for &arts; to the application.

Using &arts; also means that application does not have to do as much
|
||
|
|
work -- it can leverage the functions in &arts; to handle issues like
|
||
|
|
codecs for different media formats and control of the sound hardware.

When using &arts;, you have a number of different <link
|
||
|
|
linkend="arts-apis"><acronym>API</acronym>s</link> to choose from. The
|
||
|
|
decision of which to use depends on a number of factors, including what
|
||
|
|
type of streaming media is used (sound, &MIDI;, &CD; audio, &etc;), the
|
||
|
|
<acronym>API</acronym> features required, and whether it is written in
|
||
|
|
C++. In most cases the choice should be relatively obvious based on the
|
||
|
|
required features.

For cross-platform portability, applications that need to run on
|
||
|
|
environments other than &kde; cannot rely on &arts; being present. Using
|
||
|
|
the plug-ins paradigm is a good way to support different multimedia
|
||
|
|
environments. Making the plug-in <acronym>API</acronym> open and
|
||
|
|
documented (especially for closed source applications) also has the
|
||
|
|
advantage of allowing someone other than the application developer to
|
||
|
|
implement an &arts; plug-in.
