Audiophile FLAC CUE splitter 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. Big files WAV, DSF, DFF, APE, WavePack (.wv), mp3 are supported too. 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.

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

Tips

1. When you open directory with *.cue file, AuI ConverteR automatically add CUE file into input-file list and don't add other audio files.
2. If you open audio file in the directory, use Open files button and select only audio file(s) (not *.cue). If you select file and cue, cue will added only.

Sound quality matters

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.

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.

To minimize splitting artefacts, main window of AuI ConverteR > Parameters tab > True Gapless Mode switch should be checked (if available in your configuration)

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.

Troubleshooting

What is a cue file flac?

Here, we can discuss pair of files:

• big FLAC file;
• .cue [cue-sheet] file with time scores inside this FLAC file.

These scores marks borders between tracks, including pauses. Also, the cue-sheet file contains track name, performer and other metadata, that are displayed by an audio player software.

Codecs

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

Warning: In version earlier 9.2, before CUE + other than FLAC, WAV, AIFF, DSF file, open this file type directly to auto downloading and installing of codec.

Wrong symbols in converted files

If converted files contains wrong symbols in:
- text metadata (album, performer, track name, etc.) or
- file name,
in Settings > Metadata > select proper value in "CUE file encoding" list ("Local" is default value).

What is the best cue splitter?

There is no single criteria for everybody.
