.SH DESCRIPTION
|
|
.sp
|
|
japa (JACK and ALSA Perceptual Analyser), is a \(aqperceptual\(aq
|
|
or \(aqpsychoacoustic\(aq audio spectrum analyser. In contrast to
|
|
JAAA, this is more an acoustical or musical tool than a purely
|
|
technical one. Possible uses include spectrum monitoring while
|
|
mixing or mastering, evaluation of ambient noise, and (using
|
|
pink noise), equalisation of PA systems. For more information see
|
|
/usr/doc/japa\-0.9.2/README.
|
|
.sp
|
|
In JACK mode (\fB\-J\fP), japa creates 4 input ports (for spectrum
|
|
analysis), named \fIjapa:in_<N>\fP (where \fI<N>\fP ranges 1 to 4) and
|
|
2 output ports (for noise generation), named \fIjapa:pink\fP and
|
|
\fIjapa:white\fP\&. By default, these aren\(aqt connected to anything; use
|
|
e.g. \fBqjackctl\fP(1) or \fBjack_connect\fP(1) to connect to other JACK
|
|
clients.
|
|
.sp
|
|
In ALSA mode, the inputs and outputs are connected directly to the
|
|
ALSA device, meaning e.g. there will be 2 inputs and 2 outputs for
|
|
a typical stereo audio card. Yes, this means the pink and white
|
|
noise generators will be heard immediately on starting up japa;
|
|
if you don\(aqt need them you can silence them with e.g. \fB\-C hw:0 \-P
|
|
null\fP\&. If you get "Can\(aqt connect to ALSA", try a different device
|
|
(use \fBalsamixer\fP(1) or \fBaplay\fP(1) to get a list of them).
|

|
.INDENT 7.0
|
|
.TP
|
|
.B \fB\-s\fP \fIserver\fP
|
|
Connect to a specific JACK server. Default is \(aqdefault\(aq or
