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 have several price/functionality options, that allow to save your budget for necessary functionality.
