<br />
- <span class="commandname">flac</span> is the command-line file encoder/decoder. The encoder currently supports as input RIFF WAVE, RF64, AIFF, FLAC or Ogg FLAC format, or raw interleaved samples. The decoder currently can output to RIFF WAVE, RF64, or AIFF format, or raw interleaved samples. <span class="commandname">flac</span> only supports linear PCM samples (in other words, no A-LAW, uLAW, etc.), and the input must be between 4 and 24 bits per sample. This is not a limitation of the FLAC format, just the reference encoder/decoder.<br />

This is not a limitation of the FLAC format, just the reference encoder/decoder.<br />
<br />
- <span class="commandname">flac</span> assumes that files ending in ".wav" or that have the RIFF WAVE header present are WAVE files, files ending in ".rf64" or have the RF64 header present are RF64 files, files ending in ".aif" or ".aiff" or have the AIFF header present are AIFF files, and files ending in ".flac" or have the FLAC header present are FLAC files. This assumption may be overridden with a command-line option. It also assumes that files ending in ".oga" or ".ogg" or have the Ogg FLAC header present are Ogg FLAC files. Other than this, <span class="commandname">flac</span> makes no assumptions about file extensions, though the convention is that FLAC files have the extension ".flac" (or ".fla" on ancient "8.3" file systems like FAT-16).<br />
+ <span class="commandname">flac</span> assumes that files ending in ".wav" or that have the RIFF WAVE header present are WAVE files, files ending in ".w64" or have the Wave64 header present are Wave64 files, files ending in ".rf64" or have the RF64 header present are RF64 files, files ending in ".aif" or ".aiff" or have the AIFF header present are AIFF files, and files ending in ".flac" or have the FLAC header present are FLAC files.

<br />
Before going into the full command-line description, a few other things help to sort it out: 1) <span class="commandname">flac</span> encodes by default, so you must use <b>-d</b> to decode; 2) the options <span class="argument">-0</span> .. <span class="argument">-8</span> (or <span class="argument">--fast</span> and <span class="argument">--best</span>) that control the compression level actually are just synonyms for different groups of specific encoding options (described later) and you can get the same effect by using the same options; 3) <span class="commandname">flac</span> behaves similarly to gzip in the way it handles input and output files.<br />
<br />
<span class="code">flac -V -- -01-filename.wav</span>
</li>
</ul>
- The encoding options affect the compression ratio and encoding speed. The format options are used to tell <span class="commandname">flac</span> the arrangement of samples if the input file (or output file when decoding) is a raw file. If it is a RIFF WAVE, RF64, or AIFF file the format options are not needed since they are read from the file's header.<br />

<br />
In test mode, <span class="commandname">flac</span> acts just like in decode mode, except no output file is written. Both decode and test modes detect errors in the stream, but they also detect when the MD5 signature of the decoded audio does not match the stored MD5 signature, even when the bitstream is valid.<br />
<br />
<tt><b>flac abc.rf64</b></tt><br />

+ <br />
<tt><b>flac abc.flac <a href="#flac_options_force">--force</a></b></tt><br />
This one's a little tricky: notice that <span class="commandname">flac</span> is in encode mode by default (you have to specify <span class="argument">-d</span> to decode) so this command actually recompresses <tt>abc.flac</tt> back to <tt>abc.flac</tt>. <span class="argument"><a href="#flac_options_force">--force</a></span> is needed to make sure you really want to overwrite <tt>abc.flac</tt> with a new version. Why would you want to do this? It allows you to recompress an existing FLAC file with (usually) higher compression options or a newer version of FLAC and preserve all the metadata like tags too.<br />
