editor. For example, you might want to change the frequency response of the audio signal on
Track 1 of your project. To do this, you'd insert an equalizer plug-in on Track 1 that performs
this kind of processing in real time as you play back the audio. Most DAW applications come
with a variety of included plug-ins. Additionally, because plug-ins are treated as individual bits
of software, it is possible to add third-party plug-ins to your computer that expand the processing
options available for use in your projects, regardless of your specific DAW.
1.5.3.8 Music Composing and Notation Software
Musicians working with digital audio and MIDI often have need of software to help them
compose and notate music. Examples of such software include Finale, Sibelius, and the free
MuseScore. This software allows you to input notes via the mouse, keyboard, or external MIDI
device. Some can also read and convert scanned sheet music or import various file types such as
MIDI or MusicXML. Figure 1.53 shows a screen capture of Finale.

1.5.3.9 Working in the Linux Environment
If you want to work with audio in the Linux environment, you can do so at different levels of
abstraction.
Ardour is free digital audio processing software that operates on the Linux and OS X
operating systems. Ardour has extensive features for audio processing, but it doesn't support
MIDI sequencing. A screen capture of the Ardour environment is in Figure 1.54. Ardour allows
you to work at the same high level of abstraction as Logic or Music Creator.
