Improving Audio Performance
System Configuration
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
•Use the File > Import > Audio command to import the audio file(s) (this converts them to the
project sampling rate).
Bit Depths, and Float Resolution
SONAR supports all common bit depths, including 64. SONAR’s 32-bit mixing provides full floating-
point resolution for extended dynamic range, and precise audio processing. For maximum dynamic
range and precision, you can also choose 64-bit mixing (Audio Options dialog-General tab-64-bit
Double Precision Engine check box). SONAR can import, export, play back, and render 64-bit float
files.
A SONAR project can contain files of different bit depths. You can specify different bit depths for
playing back, recording, importing, exporting, and rendering audio (bouncing, freezing, applying
effects). To play back or record at a specific bit depth, your sound card must support that bit depth.
Notes about 64-bit files:
• 64-bit files can now be imported at their native 64-bit depth.
• At playback time 64-bit files are streamed at full 64-bit resolution when the Double Precision
engine is turned on.
• At playback time 64-bit files are converted to 32-bit when the Double Precision engine is turned
off.
• 64-bit is a choice in the File Import dialog.
• 64-bit is a choice in the Options > Global > Audio Data file bit depth fields.
• Bounce-to-track now renders at 64-bit if the render bit depth is set to 64.
• You can save and load .cwb files containing any combination of 16/24/32/64 and stereo/mono
wave files.
To Find the Bit Depth of Clips in a Project
• Right-click a clip, choose Clip Properties from the pop-up menu, and examine the Audio files
tab.
Or
• Use the File > Project Audio Files command to open the Project Files dialog, and examine the
