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 selected using the -b option. The	file will have as  many	 chan-
       nels  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	speci-
       fied, 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 included in the JACK toolkit as a result.
