jackrec \- JACK toolkit client for recording audio

.SH SYNOPSIS
|
|
.B jackrec
|
|
\-f filename \-d seconds [ \-b bitdepth ] port1 [ port2 ... ]
|
|
.SH DESCRIPTION
|
|
.B 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 \fI-b\fR 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 \fI-d\fR
|
|
option. If not specified, jackrec will record until terminated by a
|
|
signal (eg. from Ctrl-c).
|
|
.PP
|
|
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.
