SLN to W64 conversion is the process of converting audio files in the SLN (Sony Lossless) format into the W64 (Sony 64-bit Wave) format. This conversion rewraps or decodes lossless SLN audio and saves it into W64 containers that support very large file sizes and high-resolution audio suitable for professional workflows.
