FLAC Export Options
From Audacity Manual
FLAC is a compressed but lossless open source audio format. The files it produces are about half as large as the uncompressed WAV or AIFF formats, but larger than compressed, lossy formats.

FLAC Export Setup
- Level: The amount of compression used to create the FLAC file. The level settings range from 0 to 8, with 0 being fastest and 8 giving the most compression. The default level is 5. As all compression levels are lossless, the level chosen makes relatively little difference to the exported file size, but makes a considerable difference to the speed of encoding. Typically, encoding at compression level 8 is three to four times slower than level 0.
- Bit depth: Choose from 16 bit (default) or 24 bit (approximately 50% larger file size).
