ISO (aka 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 extraction guide and about sound quality comparison.
To convert ISO (aka SACD ISO) to FLAC:
WARNING: AuI ConverteR 48x44 doesn't support DVD-audio and DVD-video.
AuI ConverteR process too long file names and paths, non-Latin and forbidden characters (created from metadata) for successful output file writing. Third-party utility decode SACD ISO for additional processing with AuI ConverteR. Read whole page carefully.
* (at first time conversion or after codec reset, auto downloading of the codec will requested). View details about first-time conversion below.
** if available in purchased software configuration (check the extractor software configurations)
*** All prices at this page in the U.S. dollars without V.A.T. and other applicable taxes. The prices are recommended. Information at this page is not a public offer.
WARNING: ISO (1-bit audio, aka SACD ISO only) to FLAC is supported in price configurable Modula-R and all-included PROduce-RD
For ISO tracks, DSF, DFF with length more 3 minutes FREE demo version mute 2-second silence in the output middle
Converting of 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 at our equipment.
AuI ConverteR provides 3 filter band 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.
In the ideal case, should not be repeatable lines with lower brightness. These lines show audible distortions, that correlate with the original signal.
Bit depth and sample rate of converted files may give different playback quality at 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:
At some equipment software "Non-Optimized..." modes can cause audible noise, like in this video.
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 implemented as linear only.
Dithering is applied to extracting to 16-bit output resolution only. If target resolution is 24 bit and more (including float point), Dither button is ignored.
In the Settings > General tab:
However, your individual choices may be other, then recommended here.

SACD ripping is applied on special hardware tools to SACD ISO or DSF files. You can convert:
When you rip SACD optical disk to audio files (.dsf, .dff), long path/name of extracted file, non-Latin symbols (in metadata) may cause a error of the file creation.
SACD ISO is file, that contains DSD (Direct Stream Digital) audio and metadata from SACD optical disk.

You can extract:
SACD ripping may be possible via some hardware. Read information about SACD ripping...
SACD optical disk may be ripped with special equipment...
Ripping result is either SACD ISO or DSF or DFF (DSD files). However, ripping to ISO is more recommended due to long path and other issues when target file is DSF/DFF. Ripped SACD ISO may be converted to DSF or DFF.
Optical SACD disk may be ripped to SACD ISO file. The file may be converted to FLAC.
In general, no. However, some SONY VAIO computers have SACD abilities.
You can use audio conversion software to convert DSF to FLAC...
DSF format is a kind of audiophile music files, that contains DSD audio data and information about a song, including artworks.
Both formats can bring the same sound advantages. Actually, played recording and audio equipment makes result.
Still no information, that author knows, about the implementation of DSF file playback on VLC.
Commonly, FLAC is more recommended because no sound quality difference, but the lesser size and wider device compatibility (by metadata) of FLAC is there.
However, if you want to use high resolutions above 352/384 kHz, WAV allows to do it.
