Is W64 playable on most players (hardware and software)?
Wave64 is a proprietary format developed by Sonic Foundry Inc. In terms of audio quality, Wave64 files are identical to standard wave files, but there is one major difference:
In the file headers, Wave64 files use 64-bit values for addressing where wave files use 32-bit values. The consequence of this is that wave64 files can be considerably larger than standard wave files. Wave64 is therefore a good file format choice for really long recordings (file sizes over 2GB), e.g. live surround recordings.
Wave64 files have the same options as regular wave files and have the extension ".w64".
If the option "Show Broadcast Options for WAV64 Export" is activated in the Preferences (Record-Broadcast Wave page) a dialog will appear when you click Save to export the file.
This allows you to enter information (date and time, description strings etc.) to be embedded in the file. Note that you can enter default text strings for author, description and reference on the same Preferences page - these will automatically appear in the Broadcast Options dialog when it appears.
A Multichannel Interleave as a WAV64 file is a great way to go. Plus it keeps everything all in one place for storage. When it comes to doing something with a WAV64 Interleave, when Nuendo is used they can split the channels on importing the file so they only work on one channel at a time.
Hope this helps some.
