Hello,
I need a avoice or analog delay circuit or chips.
Any body can help me please.

Thanks in advance.

reticon

EG&G Reticon once made charge coupled device analog delay lines.

Fairchild also makes them.

**broken link removed**

If you want to use a PIC type device, you can ADC, FIFO in memory, and then DAC.

Hello,
try the Mitsubishi M65850.

Have Fun.

Audio delay

As elektrodians suggested, there are many ways to do your project.
Key words: bucket brigade, analog delay line, ...

If you need high quality go 16 bit A/D , FIFO, D/A. Complex.
For medium quality use the much simpler analog delay line.
Those are used in guitar pedal effects. Around US$120.

Look into Radio Shack (and Digikey, etc) website for analog delay line chips.

FIFO s used to be very easy to build with SRAM and FIFO controller chips, now discontinued.

I can explain a little more on how to build a FIFO using SRAMS, if you're interested.

there are some IC´s for Karaoke like BU9252 from ROHM
or M65850 from Mitsubishi but they are not easy to get so try this circuit

Try DigiKey. Look for MN3008 bucket brigade devices (BBD)made by Matsushita(Panasonic).
