    Thank you in advance.
    I'm wanting to build a small number of circuits (six min), which have the following attributes.

    A relay which actuates (dry contact) for a very brief period (like a keystroke) when activated by a single loud noise, like a hand clap. The sensitivity must be adjustable, and preferably so should the relay actuation time, as it will be used to "fire" a secondary program.

    Very important also, the latency must be very minimal indeed.

    I'm a complete newbie at all of this, but that should not be an issue (worth mentioning maybe).

    I have seen numerous vox type "kits", but I havent seen any that quite fit the bill, given the above attributes.

    Thanks all.
