Total noob here, please be gentle.
Back in 2010, this thread was started regarding audio delay curcuits: Audio delay using discrete components
After six years or so, I am wondering (hoping?) whether technology has caught up with this question, and that some expert in here (endolith?) can provide a simple and easy solution for building a delay circuit that fits my needs/fits the bill. After some research online, it seems that the minimum standards for this type of circuit, is a delay of approximately .015-.02ms. This is enough of a interruption in the microphone-speaker-loop, to eliminate most feedback issues, while still maintaining continuity between the speaker's mouth and the sound leaving the speakers.
Any takers? Thanks in advance for any help and advice!
