When Wave-64 Files are created

Wave-64 files are created behind the scenes automatically under the following usage scenarios:

• When the number of samples recorded exceeds the file size limit of a 32-bit RIFF WAV file

(approximately 2GB file size).

• When you export, bounce or freeze tracks or clips and the resultant wave size exceeds 2GB.

• When you destructively process audio effects on a SONAR clip whose duration exceeds 2GB.

• When you import audio and choose a wave file that exceeds 2GB in size (this could be a Wave-

64 file).

• When you save a CWB file and the size of any chunk in the CWB file exceeds 2GB, the entire

CWB is saved in the new Wave-64 format.

64-bit CWB files

CWB files are RIFF files with multiple WAVE chunks. Therefore, CWB files in previous versions of

SONAR were subject to the same file size limitations of normal RIFF Wav files. This could potentially

result in a CWB file that failed to save because a chunk was too large.

SONAR will automatically use the Wave-64 format if a CWB file exceeds 2GB.

Wave-64 file extension

Wave-64 files have a .w64 extension associated with them. Whenever a Wave-64 file is written,

SONAR saves it with an extension of w64.

CWP file persistence for 64-bit sample offsets

The SONAR project file format supports writing 64-bit sample offsets for regions and clips. When a

project containing 64-bit sample times is detected, saving that project automatically rewrites it in this

new format.

Note: 64-bit CWB files are incompatible with previous versions of SONAR.

Note: Projects that contain 64-bit sample times are incompatible with SONAR 6 and earlier.
