DSD ISO, SACD ISO to FLAC conversion is intended to adapt of playback format, sample rate, channel number of music files for audiophile equipment, portable players or mobile phones. Read step-by-step how to rip sacd .iso file to FLAC and about sound quality comparison.

SACD ISO to FLAC extracting (ripping)

To convert SACD ISO to FLAC file:

  1. Start conversion software ♫ AuI ConverteR 48x44.

  2. Open SACD .iso file. *
  3. Select target FLAC format at the main window Format panel.
  4. Select sample rate.
  5. Select bit depth.
  6. When target bit depth is 16 bit, dithering ON is recommended.
    (for higher resolutions Dither button will be ignored)
  7. Select target directory. (watch video, read manual)
  8. At the main window > Album art tab assign album artwork file. **
  9. Push the Start button.
  10. Wait until the end of conversion.
    (Converted (ripped) stuff is placed in the target directory)
  11. If you got audible artefacts and distortions, it is rather overload issue.
    In Settings > General > "Output attenuator" field, set "-3 dB" or "-6 dB" or use peak level normalization** to achieve maximal loudness.

Sound quality issues

Converting ISO files to FLAC is sigma-delta (aka DSD) demodulation. DSD demodulator is a low-frequency filter.

There is no strong standard of the filter to achieve the proper result. Practically, we can vary filtering band to achieve the best result on our equipment.

DSD signal is like to an oil (technological noise) in water (music).

Oil pops up. Water is sinking. Both fractions are almost separate.

We can remove upper fraction - oil. It's like low frequency filter remove high-frequency noise.

After the oil removing, only water (music) stays.

Separating quality (noise filtering) defines how the water is pure (playback sound quality).

AuI ConverteR provides 3 filter bands: optionally from 20 kHz to 100 kHz. Bandwidth may be limited depending on input or output sample rates. Output sample rate limit target signal band.

AuI ConverteR vs a converter software: DSD64 to PCM 44.1 kHz aliases
AuI ConverteR vs a converter software: DSD64 to PCM 44.1 kHz


In the ideal case, should not be repeatable lines with lower brightness. These lines show audible distortions, that correlate with the original signal.

Sound quality in the first approach:

  • high conversion quality is like an image on good photo paper;
  • low converter quality may be imagined  as the image on a paper with some defects on its surface.

Bit depth and sample rate of converted files may give different playback quality to your system. It is bound with different playback modes for combinations "bit depth + sample rate".

In general, you can convert to file in the maximal sample rate and bit depth of your DAC. But it doesn't guarantee, that you get the best result. Read details about music conversion and sound quality issues.

Extraction into PCM format applies the downsampling. Downsampling processing based on filtering with varying settings.

At Settings > General tab > set Filter mode:

  • - "Optimized resampling filter" removes frequency range upper 20 kHz (ultrasound eliminating so that remove intermodulation distortions);
  • - "Non-Optimized resampling filter" suppress signal upper 20...24 kHz (defined by input/output sample rates) - ultrasound eliminating so that remove intermodulation distortions, wider signal band;
  • - "Non-Optimized wide resampling filter" suppress signal upper 20...100 kHz (defined by input/output sample rates) so that provide a wider band of a musical signal.

At some equipment software "Non-Optimized..." modes can cause audible noise, like in this video.

Watch and share: Removing noise from high-resolution file

Therefore "Optimized..." mode is recommended as the first choice. However, you can prefer other settings.

Use minimum phase filter switch checked/unchecked minimum/linear phase filtering in "Optimized..." mode. Other modes are implemented as linear only.


Let's look at oil (noise) in water (music) that are mentioned above.

The filter choice defines kind of oil and water separation.

All filters provides high sound quality, but it give options according to your equipment and/or taste.


Dithering is applied to extracting to 16-bit output resolution only. If the target resolution is 24 bit and more (including float point), the Dither button is ignored.



AuI ConverteR has several price/functionality options that allow saving your budget for the required functionality. You can expand Modula-R abilities later via purchasing new modules.

with parallel processing, true gapless mode, level normalization, artwork assigning.





Tips and tricks

In the Settings > General tab:

  • FLAC compressing slider: set several compression levels. As rule, slider position altering gives minimum effect. The central slider position is recommended. The level doesn't impact sound quality.
  • Filter mode list: "Optimized resampling filter" is recommended. "Non-optimized ..." and "Non-optimized wide..." may cause noise and distortions.
    "Optimized G5" is most recommended filter. However, it works significantly slower than previous ones.
  • Use minimum phase filter... switch unchecking is recommended.
  • Dithering mask depth... slider recommended set to the most left position. If you convert to 16 bit, in the main window of AuI ConverteR, compare sounding with Dither button ON and OFF.

However, your individual choices may be other, than recommended here.
