NAME
       jackrec - JACK toolkit client for recording audio

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

DESCRIPTION
       jackrec	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 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, jackrec 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.
