Audio converter sound quality


Audio converters can convert audio content:

  1. without (bit-perfect): lossless formats [both input and output] and conversion without resolution altering;
  2. with sound processing.


Without sound processing

It is a lossless format repacking without audio processing (altering resolution audio, as example). It is called lossless audio converter.

In case #1, it does not matter that converter is used. There is a matter that is functionality is available. If there is real sound difference, probably, a software bug is there.

When CUE+compressed file is splitted, the splitting may be provided without re-encoding. As rule, the compressed files are divided by frames. And track border may be placed into a frame. It cause placement of part of one track content to neighbour track. Re-encoding can solve this issue.

When lossless file (FLAC, WAV, etc.) are splitted, re-encoding don't cause quality losses. But re-encoding of lossy file cause losses in splitting.


With sound processing

In case #2 (resampling, lossy compressing, bit depth altering, etc.) a converter defines sound quality (processing distortions).

As rule, speed of conversion depends on sound quality (lesser speed - higher sound quality).

Dithering is recommended for:

  • bit depth reducing to 16-bit, or
  • 16 to 16 bit file processing.

Some albums are uninterrupted (operas, live concerts). They have non-zero levels at track borders. It can cause artefacts at borders after resampling and other processing. To fix the issue True Gapless technology is used.


Which audio converter is best?

It depends on what you want primarily.

If you want sound quality - it is converter that provides minimal distortions. In audio character of distortions (accounting psychoacoustics) can impact sound. So there are no exact figures, that define the best audio converter. As rule, a proper blind hearing test can give a more exact answer to the question.



Metadata, album art


Audio converters can export album art and text metadata from source to target file.

Also, metadata editor can alter text metadata and insert/replace/delete album cover.

Some metadata formats (mp3, flac, dsf and some other) allow assigning several artworks into a single file.
