General DSF DFF conversion issues


DFF, DSF are different DSD stream containers. Sound quality doesn't depend on which container is used.

DFF to DSF conversion may be performed as lossless. Each conversion software piece should be checked though.

DFF structure based on blocks (chunks). id3 metadata may be stored as id3-chunk. However, it can cause id3-reading issues by playback software.

Standardized DSF format store metadata as id3 metadata chunk. Generally, music storing in this format is preferable to home applications.

DSD stream edition (gain altering, resampling) is lossy actions, that are provided via conversion to PCM and back. The edition losses are comparable with usual resampling losses. Pro audio software does it transparently to ears enough.

Filter ringing is one of the most visible factors there. Acoustic musical stuff has smooth transitions primarily. And ringing is not so "scary" as it looks at "synthetical" tests. Engineers minimize ringing anyway.

Cutting DFF, DSF to parts may be performed without lossy processing.

Links to the format specifications see below.

AuI ConverteR [graphical user interface, resampling, gain adjusting and others]

The converter's software editions some Modula-R configurations and all included PROduce-RD provide:

The functionality of Modula-R edition added via relevant module (license key) purchasing. The key, that is entered into Modula-R edition, opens relevant functionality.

Modules can't be added to integrated editions FREE and PROduce-RD.

AuI ConverteR 48x44. DFF to DSF

Coding to DSF audio file format available in versions:

  • FREE that has full audio quality of processing*
  • PROduce-RD or some Modula-R configurations without the limitations.

Currently this converting software work "from a box": when the relevant file is opened, a codec is automatically downloaded, installed and configured.

* WARNING: DVD-audio/video, Blu-Ray, DVD/BluRay/CD ISO are NOT supported.
For Modula-R version, SACD ISO, DSF, DFF are supported in proper configurations.
For ISO tracks, DSF, DFF longer than 3 minutes, FREE edition mutes 2-second silence in the output middle and has other restrictions. In batch conversion FREE version mutes 2 seconds in the output middle for second and the subsequent files.
Free version has processing sound quality identical commercial editions.


It needs do nothing to configure the latest versions of the conversion software. AuI ConverteR uses dffdsf converter as DFF coder and decoder.

As an alternative, you can configure the codec manually.


Manual codec installing

1. Visit download page to download dff2dsf utility or download dffdsf utility.
AuI ConverteR FREE edition has full processing quality, like commercial editions, with the limitation: 2-second silence in the middle of output file.

REMARK: AuI ConverteR latest version automatically download and install dffdsf utility. Only if it doesn't work, do it manually.

2. Unpack the zip archive. It contains three folders: linux, osx, win32 (compatible operation systems).

Connect command line tool dff2wav to AuI ConverteR 48x44 (Windows)

It is an obsolete way. Strongly not recommended.



  • Decoder dff2wav.exe have limitation: 2.8 MHz (DSD64) only.
  • With the decoder DFF to DSF is converted thru intermediate resampled filtered WAV.


How to get advantages:

The better way is using of full audio quality and abilities of PROduce-RD edition or configurable Modula-R. These editions automatically download and install dffdsf utility for better audio performance (no intermediate conversion DFF to WAV). dffdsf software repacks DFF to DSF without changing of audio data.

Some albums like operas, live concerts have non-zero levels on track borders. Or some SACD ISOs has DC bias thru all tracks. It can give clicks sometime after converting.

In this case better choice is:


Remark: In FREE edition you can't add new source format (see Settings window > Input formats tab > Input file format list). You can replace one of existing (as example dff).

To manual connect dff2wav codec (using of the codec is not recommended):

1. Download dff to wav decoder here.


2. In field Input converter executable select where placed downloaded dff to wav converter



3. In field Input converter command line type command line parameters

%inputfile% %outputfile%
