Pro Audio stores audio data separately from the rest of your projects, in
Þles placed into a special folder called the
wavedata folder . These
audio Þles are in the same format as regular Wave Þles.
Pro Audio stores audio data in a way that conserves disk space. If you
copy an audio event from one project to another, for example, Pro Audio
doesnÕt actually make a copy of the audio Þle, unless the projects use
different sampling and bit rates. Instead, it tells both project Þles that
they share the same audio Þle. If you subsequently edit a portion of the
audio in one of the projects, the edited portion is stored in a separate
audio Þle, and the corresponding portion of the original Þle is no longer
shared. On playback, Pro Audio combines all the audio Þles together as
needed to recreate the song.
Suppose you have a song called mysong.wrk , which contains several
audio events. The audio portion of the project is stored in a number of
Þles with an extension of .
wav . The exact number of Þles depends on how
many events were recorded, how much editing was performed on the
audio portion of the project, whether or not the same audio events are
shared by other projects, and other factors.
