Hi All,

Sorry if someone has asked this before but I want a certain audio input frequency (using adc) to cause a bang to occur (i.e. if someone shouts into the mic, this will set off a bang), any ideas?

For a specific frequency you should use [fiddle~].
But i think you mean amplitude, am I wrong?

So then i would suggest [threshold~]. Check out the help file.
