[Audacity-devel] Audacity and fireworks.

[julian g. <jul...@ja...>]

Dominic and the list,

I have been fairly passive on the mailing list of late, due to 
development of a computerised fireworks firing system.   You may recall 
some emails I sent with patches some time back.

The firing system makes use of audacity as the media/event player by 
utilising the label tracks.   I have generated some small patch files 
that modify the label track code by printing to stdout (simple printf) 
the name of a flag on the label track as it is played.   I use piping to 
connect audacity output to stdin of the fireworks controler software 
(also written around the wxWindows framework).

The fireworks system will be for sale, the hardware only (controller, 
breakout boxes and cables).   The software to drive it will be available 
for download, as audacity currently is.

I need to ask you if you are happy for the audacity project to be 
associated with the work I am doing on the firing system, and if so do 
you think that the group would mind if the modifications I have made to 
audacity could be incorporated in the main line code.

I have made one other modification to audacity code that makes the 
placing of the flags on label tracks easier.   When in play mode the 
flags are placed at the current play position rather than the last mouse 
click position.   This makes it easier to feel the music and insert an 
effect at the right place.  

I would also like to add a simple feature of advancing all the flags on 
a track by a fixed offset.   This is to allow time for firework effects 
to be pre-launched so that they explode in the sky at the right time in 
relation to the music.
