Audiophile CUE splitter FLAC, WAV, DSF, DFF, APE AuI ConverteR 48x44 [Mac, Windows] cut big audio files with 1 sample precision by *.cue index (musical albums) to separate files (tracks) .flac, .mp3, .wav, .dsf and other. Metadata (song information) from *.cue is exported to target files. AuI ConverteR is able to assign album artwork to target files. Bit-perfect splitting (without quality losses) is available for lossless to lossless file conversion.

To split FLAC CUE kit (divide musical album to stand-alone tracks [audio files] with 1 sample precision):

1. Launch AuI ConverteR
   
       [Download for Windows]    [  Download for Mac  ]
    
2. In main window push Open files button and select only CUE file (don't select FLAC file).

    

   

    

3. For splitting FLAC by CUE's time scores in bit-perfect mode (binary content of source and target files is identical, there are not quality losses):

   Select lossless target PCM format (FLAC, WAV, AIFF), sample rate and bit depth identical input file or set "as input"

   

    

   In Settings window (General tab) Don't make DSP... switch should be checked

Bit perfect splitting

There are losses always when:

• resampling is applied or
• lossless file (WAV, FLAC, DSF) converted to lossy (mp3, AAC, etc.) or
• DSD files converterd to PCM or back.

If bit depth is increased (example: 16 to 24 or 32 bit, 24 to 32 bit), there are not quality losses into AuI ConverteR.

Accurate split with 1 sample precision

Decoding and reencoding of FLAC files are lossless actions.

But without decoding and reencoding FLAC file may be splitted with frame (data block) precision.

It can cause placement of next track fragment to end of previous thack.

To avoid the issue AuI ConverteR split files by marks into cue-file with precision 1 sample (exact track border) without quality losses.

When mp3 (or other lossy) audio file is splitted to mp3 (or other lossy), to split with 1 sample precision there is re-encoding is happens. And target files have some losses (audible or not, we can't say exactly), comparing with original stuff.

But for cases, where splitting per audio data block cause sound penetration of next track begin to end of previous one, splitting per 1 sample may be more desirable.

Main window of AuI ConverteR > Parameters tab > True Gapless Mode switch should be checked

In Settings window Don't make DSP... switch should be checked.

In True Gapless Mode files processed sequentially. It defined necessity of connecting neighbour files borders.

Free demo insert two second pauses into 2nd and next tracks.

As rule, .cue and .flac files should have similar file names. Otherwise, AuI ConverteR try to found appropriate big audio file automatically.

Warning: Before CUE + other than FLAC, WAV, AIFF, DSF file, open this file type directly to auto downloading and installing of codec.
