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 popup menu, and

examine the Audio files tab.

•Use the File-Project Audio Files command to open the Project Files

dialog, and examine the Bit Depth column.

The following topics show you how and why to choose bit depths for various

operations.
