.w64 - Sony Wave64 Audio

The W64 audio files are related to Sony Sound Forge. The W64 file is a Sony Wave64 Audio. Sony Wave64 is a file format that`s similar to the RIFF format. The RIFF format allowed for approximately 4GB of audio data, which was sufficient to hold about 6 hours and 45 minutes of 16-bit/44.1kHz audio. The advent of multi-channel audio - such as 5.1 surround - and 24-bit/96kHz or 192kHz audio, made the RIFF format inconvenient. To accommodate the larger files, the Sony Wave64 is a true 64-bit file format designed to overcome the size limitations of the RIFF format.
