8 .B jackrec is a basic, but useful, audio recorder that will record
9 audio from 1 or more JACK ports to a file on disk. The file format is
10 always RIFF/WAV, with samples stored as signed integers. The sample
11 bit depth can be selected using the \fI-b\fR option. The file will
12 have as many channels as there are ports specified on the command line
13 - each channel will contain the data recorded from one port. The user
14 should generally specify the duration (in seconds) using the \fI-d\fR
15 option. If not specified, jackrec will record until terminated by a
16 signal (eg. from Ctrl-c).
18 This application is not intended to be a heavy duty audio recorder,
19 and originated as an example client to show how to handle threading
20 and disk I/O in a JACK client. However, it is a useful, simple
21 recorder and is included in the JACK toolkit as a result.
