About DFF
Philips created DSDIFF, the DSD Interchange File Format, for recording and mastering the Super Audio CD, which Sony and Philips launched in 1999. Studio apps save it, and tools that copy SACDs to a computer often write DFF files.
A DFF holds 1-bit DSD at 2.8 MHz or faster, often in stereo or 5.1, or DST, the lossless compression SACDs use to fit more on a disc.
No browser plays DFF by itself. Filepeek decodes DSD and DST with FFmpeg inside your browser, and Export saves a WAV or MP3 that any app or player takes.

Questions
How do I play a DFF file?
Drop it on this page or press Peek a DFF. Filepeek converts the DSD to PCM inside your browser, so it plays on any computer or phone.
What's DST?
Direct Stream Transfer, the lossless compression of Super Audio CDs. DFF files copied from an SACD often use it, and Filepeek decodes it too.
Can I convert DFF to WAV?
Yes. Choose Export, then Save as WAV, which any editing app opens, or Save as MP3 for a small copy. Drag the handles on the waveform strip to save only a part.
Is my music uploaded?
No. The DFF is decoded inside your browser and never leaves your device.
