This is a HOWTO for the Audio Location demo.

- Position the monitor and "buttons" on a table 

- Position the 6 mics so that they cover a 2mx2m space well.  The ones we used have a useful angle of 120, 60 either side of center, and a useful range of about 3m (but this drops to 2m in noisy environments).   

- Use "gimp" to produce a jpg file of approximately the same resolution as the screen, which is a plan view of the demo space.  Mark walls and furniture using coloured blocks.  It is important that this is accurate, and that it is easy for a visitor to understand the various objects depicted.

- With the origin as the top-left corner of the jpg, and with x across and y down, survey the microphones using a measuring tape.   

- Type "runad" to run the software

- Map->New and specify your jpg.  Set the dimensions in metres of the jpg as the Max x and Max y values, and max z to 10.  Show grid with a 0.1 for both horizontal and vertical.

- Use insert->mic to type in the surveyed positions of the mics.  Determine the device number by tapping the mic gently, and looking at the text output (it should list "rx 5" for mic 5, etc)

- Add "buttons" if you wish, providing command line actions for each button.  Buttons can be added by right-clicking on space, or by using the menus.

- SAVE THIS CONFIGURATION so restarting is painless (use "runad <nameofconf>" so you don't need to use the load menu)
