Wave 64 codec is a codec which produces files which comply with the Sony Wave 64 specification, created primarily to break the 4GB file limit imposed with normal Wave files, Wave64 files have 64 bit internal structures allowing for all practical extents any length audio files. The Wave 64 files contain primarily linear audio, making this a lossless codec, but the files can also contain compressed formats (such as MP3, a-law, u-law, etc..). The codec works in a similar way to the Wave codec.
