SNDFILE-INTERLEAVE(1) General Commands Manual SNDFILE-INTERLEAVE(1) NAME
sndfile-interleave - convert multiple single channel files into a multi-channel file sndfile-deinterleave - split a multi-channel into multiple single channel files SYNOPSIS
sndfile-interleave <input 1> <input 2> ... -o <output file> sndfile-deinterleave filename DESCRIPTION
sndfile-interleave and sndfile-deinterleave use libsndfile (http://www.mega-nerd.com/libsndfile/) to convert back and forth between multi- ple single channel files and a single multi-channel sound file. Run "sndfile-interleave --help" or "sndfile-deinterleave --help" for more information AUTHOR

JACK_CAPTURE(1) General Commands Manual JACK_CAPTURE(1) NAME
jack_capture - A program for recording anything from jack SYNOPSIS
jack_capture [options] bar [options] DESCRIPTION
This manual page documents briefly the jack_capture command. This manual page was written for the Debian distribution because the original program does not have a manual page. jack_capture is a cli program for recording any audio signal from jack to audio audio formats supported by libsndfile library (wav, aiff, ogg, flac, wavex, au, etc.) For more info about libsndfile see http://www.mega-nerd.com/libsndfile/api.html#open OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. -b, --bitdepth n is by default FLOAT. It can be set to either 8, 16, 24 or 32. (for relevant formats) -c, --channels n is by default 2. -p, --port port is by default set to the two first physical outputs. The "port" argument can be specified more than once. -d, --duration s Recording is stopped after "s" seconds. -z, --leading-zeros n "n" is the number of zeros to in the autogenerated filename. (-z 2 -> jack_capture_001.wav, and so on.) (default is 1) -f, --format format Selects fileformat provided by libsndfile. See http://www.mega-nerd.com/libsndfile/api.html#open (Default is wav for 1 or 2 chan- nels, and wavex for more than 2.) -pf, --print-formats Prints all sound formats provided to sndfile to screen and then exits. -v, --version Prints out version. -s, --silent Suppress some common messages printed to the terminal. -V, --verbose] Prints some extra information to the terminal. -mp3, --mp3 Writes to an mp3 file using liblame (LAME). (the --format option has no effect using this option) -mp3q, --mp3-quality n Selects mp3 quality provided by liblame. n=0 is best, n=9 is worst. Default n is 2. (0 uses the most amount of CPU, 9 uses the least) -mp3b, --mp3-bitrate n Selects mp3 bitrate (in kbit/s). Default is set by liblame. (currently 128) -ws, --write-to-stdout Writes 16 bit little endian to stdout. (the --format option, the --mp3 option, and some others have no effect using this option) -dm, --disable-meter Disable console meter -hbu, --hide-buffer-usage Disable buffer usage. -dc, --disable-console Disable console updates. Same as "-dm -hbu". -lm, --linear-meter Use linear scale for the console meter (default is dB scale) -dBr, --dB-meter-reference Specify reference level for dB meter. (default=0) -mb, --meterbridge Start up meterbridge to monitor recorded sound. -mt, --meterbridge-type Specify type. vu (default), ppm, dpm, jf or sco. -mr, --meterbridge-reference Specify reference level for meterbidge. -jt, --jack-transport Start program, but do not start recording until jack transport has started rolling. When jack transport stops, the recording is stopped, and the program ends. -jtm, --jack-transport-multi Similar to --jack-transport, but do not end program when jack transport stops. Instead, record to a new file when jack_transport start rolling again. (not implemented yet) -B, --bufsize s Initial/minimum buffer size in seconds. Default is 8 seconds for mp3 files, and 4 seconds for all other formats. -MB, --maxbufsize Maximum buffer size in seconds. jack_capture will allocate. Default is 40. (Buffer is automatically increased during -fn, --filename Specify filename. (It's usually easier to set last argument instead) EXAMPLES
