Converting Sample Rates and Bit Depths
In general, it’s better to keep the sample rate and audio bit depth of a project
consistent from start to finish, but SONAR has tools and procedures to accomplish
the following tasks:
• Preparing higher-quality audio (greater than 16-bit, 44.1 kHz) for CD burning
(CD format is 16-bit, 44.1 kHz)
• Rewriting audio files at different bit depths
• Converting the sample rate of a project
• Importing 24-bit audio into a 16-bit project
• Importing 16-bit audio into a 24-bit project
• Importing audio that has a different sample rate into a project
Here are the steps involved:
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 Midiman 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 sample rate to 44.1 kHz.
3. Next launch SONAR and use the Options-Audio command to open the Audio
Options dialog. In the General section change the Audio Driver Bit Depth to
16. Change Default Settings for New Projects to 44100 Hz for the Sampling
Rate and 16 bits for the File Bit Depth.
4. After making these adjustments, click the Wave Profiler button in the Audio
Options dialog. In some instances, with certain audio hardware configurations
you may be prompted with an audio driver error dialog during this process.
This is nothing to be concerned about. You will have to exit SONAR, re-launch,
verify the settings you made in the Audio Options dialog, and click the Wave
Profiler button again. When you can successfully run the Wave Profiler
without an audio driver error, proceed to the next step.
5. Create a new project (File-New command). The Normal option is fine for this.
6. Import the mixed down audio by using the File-Import Audio command.
7. Confirm the bit depth and sample rate of the imported audio by using the
File-Info command, and clicking File Stats. The File Stats dialog lists the
correct sample rate and bit depth.
