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.
