System information
Audio
Use the Audio tab to change the data format of the current project.
Item Description
Master bus mode Choose Stereo from the drop-down list to create a two-channel
stereo project.
Choose 5.1 Surround if you want to perform advanced 5.1-channel
mixing. For more information, see "5.1 surround projects" on page
433.
Number of stereo
busses
Enter the number of stereo busses for the project. For more
information, see "Adding Audio Busses" on page 334.
Sample rate Choose a sample rate from the drop-down list or enter a value in the
edit box.
Bit depth Select a setting from the drop-down list to specify the number of bits
used to store each sample. Higher values will increase the quality of
playback and any recordings that you make.
Resample and stretch
quality
Choose a setting from the drop-down list to determine the accuracy
with which audio files will be resampled to match your project
settings.
The Resample and stretch quality setting also determines the quality
of processing when time-stretching audio events. For more
information, see "Editing Event Properties" on page 180.
Enable low-pass filter
on LFE
Select this check box if you want to apply a low-pass filter to each
track in a 5.1 surround project that is assigned to the LFE channel. For
more information, see "5.1 surround panning and mixing" on page
436.
Applying a low-pass filter approximates the bass-management
system in a 5.1 decoder and ensures that you're sending only low-
frequency audio to the LFE channel.
Before rendering your surround project, check your surround
authoring application's documentation to determine its required
audio format. Some encoders require a specific cutoff
frequency and rolloff, and your encoder may require that no
filter be applied before encoding.
Cutoff frequency for
low-pass filter
Choose a frequency from the drop-down list or type a frequency in
the box to set the frequency above which audio will be ignored by the
LFE channel.
Low-pass filter quality Choose a setting from the drop-down list to determine the sharpness
of filter's rolloff curve. Best produces the sharpest curve.
