Light pulsing with bass

[Noel M.]

I've made a strobe light circuit using a flash tube and I want to make the light flash with the bass of any song. ANy help on how to do this would be great.

do a google search on sound to light circuits
they were all the rage 30 yrs ago

We need to see the circuit so we can interface it to a microphone or "line-input" voltage

Googling 'color organ' should give you lots of circuits.

I am. But I bet a £ to a $ that Google will give more relevant hits for 'color' than for 'colour' .
