DESCRIPTION
|
|
===========
|
|
|
|
jaaa is a graphical (X11) audio signal generator and spectrum analyser
|
|
designed to make accurate measurements. For more information see
|
|
/usr/doc/jaaa-|version|/README.
|
|
|
|
In JACK mode (**-J**), jaaa creates 8 input ports (for spectrum
|
|
analysis) and 8 output ports (for signal generation), named
|
|
*jaaa:in_<N>* and *jaaa:out_<N>* (where *<N>* ranges 1 to 8). By default,
|
|
these aren't connected to anything; use e.g. **qjackctl**\(1) or
|
|
**jack_connect**\(1) to connect to other JACK clients.
|
|
|
|
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't connect to ALSA", try a
|
|
different device (use **alsamixer**\(1) or **aplay**\(1) to get a list
|
|
of them).
|

|
OPTIONS
|
|
=======
|
|
|
|
Either **-J** or **-A** is required.
|
|
|
|
**-h**
|
|
Show built-in help message.
|
|
|
|
**-name** *name*
|
|
Set X11 client name (and JACK client name, with **-J**).
|
|
|
|
**-J**
|
|
Use JACK for audio. This option is available in JACK mode:
|
|
|
|
**-s** *server*

|
Connect to a specific JACK server. Default is 'default' or
|
|
**$JACK_DEFAULT_SERVER** environment variable.
|
|

|
**-A**
|
|
Use ALSA for audio. These options are available in ALSA mode:
|
|
|
|
**-d** *device*
|
|
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 **-C** and **-P** options.
|
|
Default: **hw:0** unless **-C** or **-P** is used.
|
|
|
|
**-C** *device*
|
|
ALSA device for capture. Default: not used.
|
|
|
|
**-P** *device*
|
|
ALSA device for playback. Default: not used.
|
|
|
|
**-r** *rate*
|
|
Sample frequency. Default: 48000.
|
|
|
|
**-p** *period*
|
|
Period size. Default: 1024.
|

|
**-n** *nfrags*
|
|
Number of fragments. Default: 2.
