Chapter 12: Importing/Exporting Audio and MIDI 125
Recalculating Waveform
Overviews
When the Display Preference for “Recom-
pute Invalid Waveforms” is not enabled,
waveforms are not displayed for audio files
that are imported.
Waveforms for these files can be displayed
with the Recalculate Waveform Overviews
command.
To display waveforms for an imported audio
region:
1 In the Audio Regions List, select any re-
gions that are not displaying their wave-
forms.
2 Choose Recalculate Waveform Over-
views from the pop-up menu in the Audio
Regions List.
Loading Audio Files with
Drag & Drop
Pro Tools provides you with a convenient
method of batch loading any number of
audio files into an open session.
To batch load audio files into a session:
1 Open the Pro Tools session.
2 From the desktop, locate the audio files
you want to import. Make sure the files
match the session’s file type, bit depth, and
sample rate.
3 Drag the audio files onto the Pro Tools
application icon.
The audio files are automatically imported
and appear in the Audio Regions List. If a
stereo interleaved file was imported,
Pro Tools converts it to two mono files and
saves them to the “Audio Files” folder for
the current session.
Transferring Audio from CD
(Macintosh Only)
Pro Tools allows you to transfer audio
tracks from an audio CD with the Import
Audio From Movie Audio command. Since
the transfer is made in the digital domain,
there is no signal loss.
The sample rate for audio CDs is 44.1 kHz.
Therefore, if your session’s sample rate is
set to 48 kHz, Pro Tools will convert the
sample rate for the imported audio. Before
importing CD audio, make sure to set the
Conversion Quality Preference accord-
ingly. See “Conversion Quality” on
page 126 for details.
When importing a CD audio track,
Pro Tools first imports it as QuickTime
movie. The imported movie is then con-
verted to Sound Designer II audio files,
which can be used in your Pro Tools ses-
sion. Before importing CD audio, make
sure your hard disk has enough space for
both the imported movie file and the con-
verted audio files.
To import a CD audio track:
1 Insert the audio CD into your CD-ROM
drive.
2 Choose Movie > Import Audio From
Other Movie.
3 Locate and select the audio track to be
imported, then click Convert.
