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-|version|/README. + +In JACK mode (**-J**), japa creates 4 input ports (for spectrum +analysis), named *japa:in_<N>* (where *<N>* ranges 1 to 4) and +2 output ports (for noise generation), named *japa:pink* and +*japa:white*. 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. Yes, this means the pink and white +noise generators will be heard immediately on starting up japa; +if you don't need them you can silence them with e.g. **-C hw:0 -P +null**. 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.
