![]() Of FLAC’s metadata system, see the page titled ‘About the FLAC Format’ on To maximize the compression rate or speed, or want to use the full power Specifying new tags, seekpoints, cuesheet, padding, etc.).įlac has been tuned so that the default settings yield a good speed vs.Ĭompression tradeoff for many kinds of input. Preserve all the metadata unless you override it with other options (e.g. In other words, you can specify aįLAC or Ogg FLAC file as an input to the encoder and it will decoder itĪnd re-encode it according to the options you specify. Match the stored MD5 signature, even when the bitstream is valid.įlac can also re-encode FLAC files. They also detect when the MD5 signature of the decoded audio does not Both decode and test modes detect errors in the stream, but In test mode, flac acts just like in decode mode, except no output file WAVE, Wave64, RF64, or AIFF file the format options are not needed since Input file (or output file when decoding) is a raw file. Theįormat options are used to tell flac the arrangement of samples if the The encoding options affect the compression ratio and encoding speed. If you are encoding/decoding from stdin to a file, you should use the -o The original file is not deleted unless –delete-input-file is ![]() (meaning for encoding, the extension will be replaced with “.flac”, orĪppended with “.flac” if the input file has no extension, and forĭecoding, the extension will be “.wav” for WAVE output and “.raw” for raw The desired operation on each input file to similarly named output files Is used as input, flac will write to stdout. If only one inputfile is specified, it may be “-“ for stdin. Depending on which way is chosen,Įncoding, decoding, analysis or testing options can be used, see section ![]() Invocation, but can be switch to decoding with -d, analysis with Skip to the examples below for examples of some common tasks.įlac will be invoked one of four ways, depending on whether you areĮncoding, decoding, testing, or analyzing. the order in which options are specified is generally not important.flac behaves similarly to gzip in the way it handles input and output.They take priority over the compression level no matter the order Specific encoding options (described later) and you can get the sameĮffect by using the same options. 8 (or –fast and –best) that control theĬompression level actually are just synonyms for different groups of flac encodes by default, so you must use -d to decode.(or “.fla” on ancient “8.3” file systems like FAT-16).īefore going into the full command-line description, a few other things The convention is that FLAC files have the extension “.flac” Other than this, flac makes no assumptions about file extensions, though Or “.ogg” or have the Ogg FLAC header present are Ogg FLAC files. Or have the FLAC header present are FLAC files and files ending in “.oga” Have the AIFF header present are AIFF files, files ending in “.flac” RF64 header present are RF64 files, files ending in “.aif” or “.aiff” or Header present are Wave64 files, files ending in “.rf64” or have the Header present are WAVE files, files ending in “.w64” or have the Wave64 ![]() To RIFF WAVE, Wave64, RF64, or AIFF format, or raw interleaved samples.įlac only supports linear PCM samples (in other words, no A-LAW, uLAW,Įtc.), and the input must be between 4 and 32 bits per sample.įlac assumes that files ending in “.wav” or that have the RIFF WAVE analyze ] [ infile.flac | infile.oga |įlac is a command-line tool for encoding, decoding, testing andįlac supports as input RIFF WAVE, Wave64, RF64, AIFF, FLAC or OggįLAC format, or raw interleaved samples.
