How to Convert ISO to DSF on Mac OS, Windows [Step-by-step Guide]

Tutorials

ISO (a.k.a. SACD ISO) to DSF, DFF (DSD audio files) extraction in used to playing back at audiophile apparatus or music stuff editing. DSF format is more preferable, because it support metadata (track, album, performer names and other) standard way. Watch video tutorial "How to convert ISO to DSF"

Extract ISO to DSF, DFF

To convert ISO (1-bit, aka SACD ISO) to DSF, DFF:

Start conversion software ♫ AuI ConverteR 48x44.

[Download for Windows] [ Download for Mac ]
Open *.iso file.*
At main window > Album art assign album artwork **
At main window > Output panel > select DSF or DFF format
At main window > Output panel > select sample rate (bit-perfect extraction at 2.8 MHz only)
Select target directory (see more in video)
Push Start button
Wait until end of conversion

Preparations for сonversion

Launch AuI ConverteR 48x44 (see ISO to DSF converter configurations)
Open Settings > CD ripper/ISO tab

Click OK button in Settings window
(Optionally) Continuous-album extraction (opera, concert, show or same ones): the main window > Parameters tab check "True gapless mode"*
Binary identical (bit-perfect) extraction mode: the Settings window > General tab check "Don't make DSP ..." switch. Target sample rate must be 2.8 MHz (D64)

General information and sound quality matters

SACD ISO is file-container with tracks (songs) included in musical album. The file-container may contains mixes (variants) of album: stereo and/or multichannel.

Read educational article about SACD ISO and DSF audio files >

Multichannel variant may be played back at multichannel system or downmixed 5.1 in 2.0 to playback at stereo equipment or headphones.

Downmixing may be performed inline ("on fly" into player) or offline (convert ISO to DSF 2.0 - with/without downmixing - before playback via music converter). Offline stereo extraction/conversion save disk space at portable musical device's hard disk. Therefoe you can place more music at digital music player or mobile phone.

The file-container have sample rate 2.8 MHz and bit depth 1 bit sigma-delta modulation / DSD (the author have no information about higher sample rates in the containers).

The file-container's stuff may be extracted in bit-perfect mode (without altering). There is binary content the container and extracted stuff is identical. It is possible at 2.8 MHz sample rate only.

Also the container's stuff may be resampled so that playback at D128 and higher DAC or digital music player. Equipment have several playback modes (audio resolutions), that can cause individual distortion level of the each mode. Using of mode with minimal distortions, can improve sound quality.

Also read some sound quality issues below.

Conversion ISO to DFF is not recommended. Because DFF don't support metadata (song, album names, performer, year, artwork) standard way. Theoretically, metadata may be built into DFF technically as non-standard information block. However, playback software/hardware will ignore it, as rule.

If target sample rate is D128 / D256 / D512 / D1024 resampling processing is used. Resampling processing based on filtering. These firters have several settings.

At Settings > General tab:

Filter mode list:
"Optimized resampling filter" cut frequencies upper 20 kHz (eliminating of intermodulation distortions by ultrasound);
"Non-Optimized resampling filter" cut frequencies upper 20...24 kHz (depend on input/output sample rates) - eliminating intermodulation distortions by ultrasound, wider signal band;
"Non-Optimized wide resampling filter" cut frequencies upper 20...100 kHz (depend on input/output sample rates).
