JACK_REC(1)		     General Commands Manual		     JACK_REC(1)

NAME
     jack_rec - JACK toolkit client for recording audio

SYNOPSIS
     jack_rec -f filename -d seconds [ -b bitdepth ] port1 [ port2 ... ]

DESCRIPTION
     jack_rec is a basic, but useful, audio recorder that will record audio from
     1 or more JACK ports to a file on disk. The file format is always RIFF/WAV,
     with  samples  stored  as	signed integers. The sample bit depth can be se-
     lected using the -b option. The file will have as many  channels  as  there
     are  ports  specified  on	the command line - each channel will contain the
     data recorded from one port. The user should generally specify the duration
     (in seconds) using the -d option. If not specified,  jack_rec  will  record
     until terminated by a signal (eg. from Ctrl-c).

     This  application	is  not  intended to be a heavy duty audio recorder, and
     originated as an example client to show how to handle  threading  and  disk
     I/O  in  a JACK client. However, it is a useful, simple recorder and is in-
     cluded in the JACK toolkit as a result.
