What is a .W64 file?
The W64 file format is an audio container developed by Sony to overcome the 4GB size limitation of the WAV format. It supports high-quality, uncompressed audio data, making it suitable for professional audio editing and storage.
Background
The W64 format was introduced by Sony to address the limitations of the traditional WAV format, particularly its inability to handle files larger than 4GB. This makes W64 ideal for professional audio applications where high-resolution audio and long recording times are common. The format is primarily used in professional environments, such as recording studios and for film production, where high fidelity and large file sizes are necessary. Despite its advantages, the format is not widely supported outside of professional audio software, which limits its use among casual users. However, its ability to store large amounts of high-quality audio data makes it a valuable tool for audio professionals.
