856 Improving Audio Performance
System Configuration
While you must choose a playback timing master, you can route audio
output through any number of devices at once. For example, suppose your
computer has both a high-end audio card and a basic built-in sound card.
You should choose the high-end sound card as the record and playback
timing master. However, using the buses in the Console or Track views,
you could create a headphone or monitor mix and route it through the built-
in sound card.
Sampling Rates
SONAR supports all common sampling rates. Only one sampling rate is
allowed per project. It’s usually better not to change the sampling rate of a
project, because this involves exporting your tracks one at a time, and then
importing them at the new sampling rate. During this process you lose clip
boundaries, envelopes, and other separate data that is mixed into the
exported tracks.
To Set the Sampling Rate for New Projects
1. Open the Audio Options dialog (Options-Audio command), and on the
General tab, change the Sampling Rate field to the desired number.
You can choose from the available options, or enter any number that
your hardware supports.
2. Click OK.
To Change the Sampling Rate of a Project
1. Select an audio track and use the File-Export Audio command to
open the Export Audio dialog.
2. Select the options you want, and click Export to export the track.
3. Repeat steps 1 and 2 for all the audio tracks you want to convert.
4. After you’ve exported all the tracks you want to convert, open the Audio
Options dialog (Options-Audio command), and on the General tab,
change the Sampling Rate field to the desired number.
5. Use the File-New command to open a new project.
6. Use the File-Import Audio command to open the Import Audio dialog.
7. Select the audio files you just exported (hold down the Ctrl key while
you click each one), and click Open to import the files.
SONAR imports the selected files at the new sampling rate.
To Import Audio That Has a Different Sampling Rate
