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.
