- .SH SYNOPSIS
- .sp
- jaaa \fB\-J\fP [\fB\-name\fP \fIname\fP ] [\fB\-s\fP \fIserver\fP]
- .sp
- jaaa \fB\-A\fP [\fB\-name\fP \fIname\fP ] [\fB\-d\fP \fIdevice\fP] [\fB\-C\fP \fIdevice\fP ] [\fB\-P\fP \fIdevice\fP ] [\fB\-r\fP \fIrate\fP] [\fB\-p\fP \fIperiod\fP] [\fB\-n\fP \fInfrags\fP]
- .SH DESCRIPTION
- .sp
- jaaa is a graphical (X11) audio signal generator and spectrum analyser
- designed to make accurate measurements. For more information see
- /usr/doc/jaaa\-0.9.2/README.
- .sp
- In JACK mode (\fB\-J\fP), jaaa creates 8 input ports (for spectrum
- analysis) and 8 output ports (for signal generation), named
- \fIjaaa:in_<N>\fP and \fIjaaa:out_<N>\fP (where \fI<N>\fP ranges 1 to 8). 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. 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).
- .SH OPTIONS
- .sp
- Either \fB\-J\fP or \fB\-A\fP is required.
- .INDENT 0.0
- .TP
- .B \fB\-h\fP
- Show built\-in help message.
- .TP
- .B \fB\-name\fP \fIname\fP
- Set X11 client name (and JACK client name, with \fB\-J\fP).
- .TP
- .B \fB\-J\fP
- Use JACK for audio. This option is available in JACK mode:
- .INDENT 7.0
- .TP
- .B \fB\-s\fP \fIserver\fP
- Connect to a specific JACK server. Default is \(aqdefault\(aq or
- \fB$JACK_DEFAULT_SERVER\fP environment variable.
- .UNINDENT
- .TP
- .B \fB\-A\fP
- Use ALSA for audio. These options are available in ALSA mode:
- .INDENT 7.0
- .TP
- .B \fB\-d\fP \fIdevice\fP
- ALSA device for capture and playback. This option sets the
- playback and capture devices to the same device. For separate
- capture and playback, use the \fB\-C\fP and \fB\-P\fP options.
- Default: \fBhw:0\fP unless \fB\-C\fP or \fB\-P\fP is used.
- .TP
- .B \fB\-C\fP \fIdevice\fP
- ALSA device for capture. Default: not used.
- .TP
- .B \fB\-P\fP \fIdevice\fP
- ALSA device for playback. Default: not used.
- .TP
- .B \fB\-r\fP \fIrate\fP
- Sample frequency. Default: 48000.
- .TP
- .B \fB\-p\fP \fIperiod\fP
- Period size. Default: 1024.
- .TP
- .B \fB\-n\fP \fInfrags\fP
- Number of fragments. Default: 2.
