Bit depths for exporting audio
You can choose the bit depth of exported files from SONAR. Unless you are burning a CD or DVD,
or are concerned about storage space, you can export files at 32 bits (or even 64) to preserve the
precision of any audio processing that was done to the files.
To choose an exporting bit depth
1. Use the File > Export > Audio command to open the Export Audio dialog.
2. In the Bit Depth field, select the desired number.
3. Choose other options and click OK.
Bit depths for rendering audio
You can choose the bit depth that SONAR uses for such operations as bouncing tracks, freezing
tracks, and applying effects (these processes are referred to as rendering). This bit depth is set at 32
by default, which allows large level changes without clipping, and with greater dynamic range,
especially in soft parts of your music. You can also render at 64 bits for greatest precision.
To choose a rendering bit depth
1. Go to Edit > Preferences > File - Audio Data.
2. Under File Bit Depths, change the Render Bit Depth field to the desired number.
3. Click OK.
Preparing higher-quality audio for CD burning
If your project uses a different sampling rate from 44,100, or contains files that are not 16-bit, use
this procedure to prepare your project for CD-burning:
To prepare higher-quality audio for CD burning
1. Use the File > Export > Audio command to open the Export Audio dialog. Choose RIFF Wave
in the Files of Type field, Export to Stereo File(s) in the Format field, and 16 in the Bit Depth
field.
2. After exporting the audio, close SONAR and open up your sound card control panel (for M-Audio
cards, usually the Delta Control Panel, for Echo Audio, usually the Echo Console, for MOTU it's
the 324 console, etc.) Once the control panel is open, change the setting for your sampling rate
to 44.1 kHz.
3. Next launch SONAR, go to Edit > Preferences > Audio - Driver Settings and change the
Audio Driver Bit Depth to 16. Change Default Settings for New Projects to 44100 Hz for the
Sampling Rate.
