Microphone Echo/delay IC datasheet.

[electronics_shamim]

Sirs,

Can anyone tell me with datasheet of the easily available Microphone delay/reverbing/echo IC. I need this to fit it unto my Tape Deck at the Mic input?

Any suggestions on this front are welcome.

Regards,
Shamim

Sir,

While thanking you for the reply, it is very cumbersome to get the IC in India and to make a pcb. Rather, I would prefer a simple circuit or complete schematic/pcb layout/component layout with IC datasheet. So, that i can make out a pcb for that and fit it unto my mic input (tape deck) and the delay adjustable by volume control to a max of (120 or 130 us. arppx.). Does any circuit have this facility?

I think simple transistor (cascading form) built around some R/C network will also have some echo effect.

I appreciate your immediate feedback and also need help from you further.

Regards,
Shamim-India.

You won't get much resolution without specialized chips. Here is an article about a simple form of audio delay using 1 bit ADC. Perhaps this will help.

You could just buy a karaoke and use the circuit in it.
