JACKREC(1)JACKREC(1)NAMEjackrec - JACK toolkit client for recording audio
SYNOPSISjackrec-f filename -d seconds [ -b bitdepth ] port1 [ port2 ... ]
DESCRIPTIONjackrec 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.
