I downloaded a bunch of DSD music in DFF format from the Internet. I wanted to edit the music's tags and categorize them, but then I remembered that DFF format does not have editable tags. However, DSF format, which is at the same level of DSD lossless as DFF format, can edit tags, and it does not affect the sound quality. I was thinking about how to convert DFF to DSF format, and I found a software in a video on YouTube that perfectly solved the problem of converting to DSF format lossless!
