Perhaps in a far, far away future I will do a FX generator/editor or at least a register editor for the AY-soundchip. Until that time this feature might help you doing sound effects.
There is a (discontinued - but runable on emulators) windows program called:
AY Sound FX Editor
Which can be found at: https://shiru.untergrund.net/software.shtml
With that editor you can save files in a "*.afx" format. These files contain AY register values in a slightly compressed format. These register storages are meant to contain sound effects.
With the software come about 200 different sound effects which you can use "out of the box" - or edit them yourself. The program looks like:

AYFX
The copyright status of the program is unkown, there is no hint whatsoever regarding copyright. The programer seems to be known as "Shiru". Thanks for your software!
Right clicking on such a file allows you to "convert" it to vectrex usage (including sample code). The vectrex "player"-code was done by a proboard member which goes by the name "Vectrexrc"... Thanks!
Nothing more - nothing less...
