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  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, 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.
