DSDIFF Audio

Audio

DFF commonly contains DSDIFF audio. It differs from DSF in container/metadata behavior; DST-compressed content needs appropriate support. DFF support does not imply every variant. Inspect indexing, tags, channels and rate.

Opening steps

Choose your environment or purpose to see its steps.

Verify DFF support before playback

DSF support does not guarantee DFF support.

  1. Check DFF and encoding support in the application’s documentation.
  2. Open a copy and inspect rate/channels.
  3. Audition the beginning and ending.
Diagnose failure from file information

Distinguish internal encoding from device output.

  1. Inspect information with a compatible analyzer.
  2. Compare DSD rate, compression and channel support.
  3. Ask the producer for application/export settings when unclear.
Make a destination-compatible copy

Use supported conversion for DSF or PCM output.

  1. Confirm the required container/playback mode.
  2. Export separately using a compatible application.
  3. Compare titles, duration, channels and levels.

Menu labels and support vary by app, OS and version. Preserve the original before making changes.

Troubleshooting by symptom

  • DFF alone fails: distinguish DSF from DSDIFF/DST support.
  • No titles: inspect metadata and player support.
  • One long recording: check track indices/edit markers.
  • DSF works but DFF fails: inspect container and encoding support.
  • Missing title/artwork: inspect source metadata and player handling.
  • Changed level after conversion: compare PCM processing and source playback.

DFF → DSF / PCM audio

  1. Identify compression/structure and choose a compatible tool.
  2. Determine whether the workflow retains DSD or converts to PCM; compare audio and metadata.
  3. Retain DFF and provenance after making a listening copy.

Renaming does not change containers; verify PCM conversion and metadata transfer independently.

Check DFF and DSF independently

Both relate to DSD, but import and metadata support can differ; inspect the individual file.

Separate archival and listening copies

Retain DFF and make compatible listening copies as needed, recording conversion settings.

Missing titles do not automatically mean damaged audio; verify duration and metadata separately.

Questions and answers

Does DFF support imply DST?

No; check that separately.

Can I rename it to DSF?

No; the structures differ.

Is WAV an identical archive?

PCM conversion changes representation; retain DFF.

Does a missing title mean damaged audio?

Inspect complete playback and metadata separately.

Does every DSD player accept DFF?

Check the product’s supported container, encoding, rates and channels.
