Encoder: FLAC

Jeremy Herbison edited this page Oct 5, 2019 · 8 revisions

A managed wrapper for the reference implementation of the Free Lossless Audio Codec. On Windows and MacOS, AudioWorks includes the official libFLAC version 1.3.3. On Linux, the system-installed library is used.

FLAC is the most common and widely-supported lossless audio format. It is supported natively on most flavors of Linux and on Windows 10, but not by iTunes (which favors ALAC).

Encoder settings

The encoder defaults mirror those of the reference command-line tool.

CompressionLevel

Default: 5 (0 = fastest, 8 = highest)

Determines the trade-off between file size and compression time. Because FLAC is a lossless codec, there is never any impact on sound quality.

SeekPointInterval

Default: 10 (0 = disabled, 600 = maximum)

The interval (in seconds) between seek points. Seek points facilitate fast seeking during playback.

Padding

Default: 8192 (0 = disabled, 16775369 = maximum)

The amount of padding (in bytes) added to the beginning of the file. Padding allows for the later addition of metadata without having the re-write the entire file.
