jack_capture is a program for recording sound files with JACK.
|
|
|
|
* Autogenerated filenames are unique and humanly readable.
|
|
|
|
* The 4GB size barrier for wav files is handled by continuing
|
|
writing to new files when reaching 4GB.
|
|
|
|
* Supports all soundfile formats supported by sndfile.
|
|
(wav, aiff, ogg, flac, wavex, au, etc.) (option: -f <format>)
|
|
|
|
* Supports mp3 by using liblame. (option: -mp3)
|
|
|
|
* Option for writing raw 16 bit data to stdout. (option: -ws)
|
|
|
|
* Built-in console meter, plus option for automatically starting and stopping
|
|
the Meterbridge jack meter program. Port connections to Meterbridge
|
|
are done automatically, and on the fly, by jack_capture.
|
|
|
|
* jack_capture can connect to any input or output jack port.
|
|
|
|
When "connecting" to a jack input port (i.e. a writable port), jack_capture
|
|
constantly monitors which jack ports which are connected
|
|
to that input port, and makes sure jack_capture is always
|
|
connected to the same ports.
|
|
|
|
In other words, jack_capture will reconnect its ports automatically during
|
|
recording to match the connections of the ports.
|
|
This is for instance convenient when recording the playback ports since
|
|
jack_capture can be started first, and then other programs can start
|
|
and stop at any moment while all sound still should be recorded.
|
|
|
|
* No limit on the number of jack ports jack_capture can connect to.
|
|
(I.e. the --port argument can be specified more than once, plus that
|
|
it accepts wildcard arguments. For instance, jack_capture --port "*" will
|
|
connect to all current jack ports, both input and output ports, except
|
|
jack_capture's own ports.)
|
|
|
|
* Buffers are automatically increased during runtime to prevent
|
|
underruns and to avoid wasting memory by preallocating too much.
|
|
|
|
* The disk thread is automatically reniced to a higher priority when
|
|
using more than half of the buffer.
|
|
|
|
* Significantly better recording performance than Ardour. (probably because
|
|
jack_capture writes all channels into only one file and that it is
|
|
not creating peak files). (tested on athlonXP)
|
|
|
|
* No problem writing at least 256 channels of 32 bit wav at once to a
|
|
local hard drive. (tested on icore7)
|
|
|
|
Optional runtime dependencies are meterbridge and lame.

|
This package uses POSIX filesystem capabilities to execute with
|
|
elevated privileges (required for realtime audio processing). This
|
|
may be considered a security/stability risk. Please read
|
|
http://www.slackbuilds.org/caps/ for more information. To disable
|
|
capabilities, pass SETCAP=no to the script.
