jack_capture

============

jack_capture is a program for recording soundfiles with jack.
The default operation of the program is executed by writing "jack_capture"

in the terminal without any extra command line options:
    $ jack_capture
...which will record what you hear in your loudspeakers

into a stereo wav file.
Most important new features since 0.9.36

========================================

* Direct support for mp3 using liblame.

* Console cleanup. Terminal should not be messy

   when quitting jack_capture.

* Better buffering schemes.

* Less used memory.
Features

========

* 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 )
* 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 the input port, and make 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.

   (handled by using lockless atomic fifo/lifo queues to store

   temporary sound data instead of ringbuffers)
* 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)
