Tutorial how to convert ISO to FLAC under Mac OSX, Windows to playback at audiophile music equipment. Here extraction from 1-bit audio stuff is discussed only. Also watch video tutorial.
There are several alternative extracting software, that may have different distortions and functionality.

Tutorial: How to convert ISO to FLAC under Mac and Windows

 


Preparation

  1. Launch AuI ConverteR 48x44 (see capable configurations)
  2. Open Settings > CD ripper/ISO tab
  3. Select stereo/multichannel target stuff - check/uncheck "Force read stereo track", respectively
  4. Skip pause before first track: check "Skip pause for first ISO track"
  5. Skip pause between tracks: check "Skip pause for all tracks"
    Between tracks pauses may contains. Sometimes clicks contains into the pauses.


    Additional information

    Bit perfect extraction allow extract binary content of disk image as is.

    In Settings > General > check "Don't make DSP..." switch


     

  6. Click OK button
  7. Convert live concert, opera and same: at main window > Parameters check "True gapless mode"*

  4. Select sample rate
  5. Select bit depth
  6. When target bit depth is 16 bit, dithering ON is recommended.

Sound quality issues

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

At Settings > General tab > set Filter mode:

  • - "Optimized resampling filter" remove 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 wider band of musical signal.
  • At some equipment sotware "Non-Optimized..." mode can cause audible noise, like here >.
  • So "Optimized..." mode is recommended as first choise. 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.
  • Dither work in 16 bit PCM extraction only. If target resolution upper 16 bit (including float point formats), Dither button is ignored.

 

 


Convert ISO to FLAC - Configurations

The converter have several available editions, that distinguish by functionality.

There are integrated factory configured editions and user-configured Modula-R.

User configured edition is purchased by separate modules. Each module have own functionality.

However integrated editions have price lesser than identical module kit.

 

ISO FLAC conversion available in Modula-R, Audiophil-E, PROduce-R, PROduce-RD editions.

Artwork assigning available in Modula-R (with Metadata editor module), PROduce-R, PROduce-RD editions.

True gapless mode available in Modula-R (with True Gapless Conversion module), PROduce-RD editions.
