&dhfirstname; &dhsurname; 2000 &dhusername; &dhdate; &dhucpackage; &dhsection; &dhpackage; Free Lossless Audio Codec flac OPTION infile outfile This manual page documents briefly the flac command. This manual page was written for the &debian; distribution because the original program does not have a manual page. Instead, it has documentation in HTML format; see below. A summary of options is included below. For a complete description, see the HTML documentation. -d Decode (default behavior is encode) -t Test a flac encoded file (same as -d except no decoded file is written) -a Analyze a flac encoded file (same as -d except an analysis file is written) -s Silent mode (do not write runtime encode/decode statistics to stdout) --skip samples Skip the specified number of samples at the beginning of the input file (can be used for both encoding and decoding) --a-rtext Includes the residual signal in the analysis file. This will make the file very big, much larger than even the decoded file. --a-rgp Generates a gnuplot file for every subframe; each file will contain the residual distribution of the subframe. This will create a lot of files. --lax Allow encoder to generate non-Subset files -S { # | X | #x } Include a point or points in a SEEKTABLE. Using #, a seek point at that sample number is added. Using X, a placeholder point is added at the end of a the table. Using #x, # evenly spaced seek points will be added, the first being at sample 0. You may use many -S options; the resulting SEEKTABLE will be the unique-ified union of all such values. With no -S options, flac defaults to '-S 100x'. Use -S- for no SEEKTABLE. Note: '-S #x' will not work if the encoder can't determine the input size before starting. Note: if you use '-S #' and # is >= samples in the input, there will be either no seek point entered (if the input size is determinable before encoding starts) or a placeholder point (if input size is not determinable) -P bytes Tell the encoder to write a PADDING metadata block of the given length (in bytes) after the STREAMINFO block. -P 0 implies no PADDING block, which is the default. This is useful if you plan to tag the file later with an APPLICATION block; instead of having to rewrite the entire file later just to insert your block, you can write directly over the PADDING block. -b blocksize Default is 1152 for -l 0, else 4608; must be 192/576/1152/2304/4608/256/512/1024/2048/4096/8192/16384/32768 (unless --lax is used) -m Try mid-side coding for each frame (stereo input only) -m Loose mid-side coding for all frames (stereo input only) -0..-9 Fastest compression..highest compression (default is -6). These are synonyms for other options: -0 Synonymous with -l 0 -1 Synonymous with -l 0 -M -2 Synonymous with -l 0 -m -r # (# is automatically determined by the block size) -3 Reserved -4 Synonymous with -l 8 -5 Synonymous with -l 8 -M -6 Synonymous with -l 8 -m -r # (# is automatically determined by the block size) -7 Reserved -8 Synonymous with -l 32 -m -r # (# is automatically determined by the block size) -9 Synonymous with -l 32 -m -e -r 16 -p (very slow!) -e Do exhaustive model search (expensive!) -l max_lpc_order 0 => use only fixed predictors -p Do exhaustive search of LP coefficient quantization (expensive!). Overrides -q, does nothing if using -l 0 -q bits Precision of the quantized linear-predictor coefficients, 0 => let encoder decide (min is 5, default is 0) -r level Residual partition order (0..16). 0 => none, default is 0, above 4 doesn't usually help much) -V Verify a correct encoding by decoding the output in parallel and comparing to the original -S- -m- -M- -e- -p- -V- --lax- These flags can be used to invert the sense of the corresponding normal option. -fb Big-endian byte order -fl Little-endian byte order -fc channels Set number of channels. -fp bits_per_sample Set bits per sample. -fs sample_rate Set sample rate (in Hz). -fu Unsigned samples (default is signed) -fr Force to raw format (even if filename ends in .wav). -fw Force to RIFF WAVE. The programs are documented fully by HTML format documentation, available in /usr/share/doc/flac/html on &debian; systems. This manual page was written by &dhusername; &dhemail; for the &debian; system (but may be used by others).
