DSF to FLAC conversion. Overview

Sound quality of conversion

Various audio conversion software can provide different sound qualities. It is a noise and distortion levels, primarily.

AuI ConverteR vs a converter software: DSD64 to PCM 44.1 kHz


In this picture, we can see spectrogram of PCM audio file in CD resolution. This file is result of convertstion from DSD file.

Vertical axis is a frequency. Upper along the axis means higher frequency. Horisontal axis is time. The future in the right.

We can see original signal as the bright line. It is clearly visible on the upper part of the picture.

The distortions are visible as the repeatable lines with lower brightness. These lines show audible distortions, that correlate with original signal.

Conversion speed may depend on conversion accuracy. Higher accuracy requires more computing resources and time.

Sometimes, reducing playback noise level can be achieved via frequency band reducing of converted music stuff.

Check AuI ConverteR's Settings > General tab > Filter mode list. If you listen to noise during playing back of converted FLAC, use "Optimized" mode for DSF to FLAC conversion.

"Optimized G5" mode is slower and recommended for professional using rather. The mode causes a shorter ringing length.

FLAC data compression

FLAC compression level doesn't alter audio quality of music. After unpacking binary content is the same for any compression level.

Check AuI ConverteR's Settings > General tab > FLAC compressing slider.



Metadata from input files may be exported into output ones, including artwork.

AuI ConverteR with metadata editor option allows batch editing metadata of albums (group of files) and assigning own album artwork.
