Sony Wave-64 support
SONAR 6 and earlier wrote wave files based on the RIFF wave file format. The RIFF format has an
inherent file size limitation of 2GB.
SONAR fully supports reading and writing to the Sony Wave-64 format, which has a limit of
8,388,608 terabytes!
SONAR only creates Wave-64 file when needed. The Wave-64 format allows an application to
dynamically switch from classic RIFF WAVE to Wave-64 format even if the data was originally
created as a RIFF wave file. SONAR detects when a file will exceed 2GB and will dynamically switch
to the new Wave-64 format.
The table below shows the maximum duration for a stereo WAVE file before we hit the 2GB limit, as
well as the max duration for a stereo Wave-64 file before we hit the 8,388,608 terabyte limit.
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
