Default Audio delay circuit

Hello,
I was looking for analog delay circuit of 2seconds, which can delay the audio signal (input) by digital or active\passive analog components and have delayed analog output.

I have come across one circuit but not able to find the components which is attached to this thread, that may also help you to suggest me any other circuit or method.

Regards,
Dileep

What bandwidth do you need? That circuit's for voice as far as I can see, it runs at 64kbits per second.

<edit> Note to mods: I see this was cross-posted to Analog Line too - a better place for it would be Digital Line as its not really possible to do analog delay of 2s and that pdf is a digital solution.

You could have a look at this chip : http://www.holtek.com.tw/pdf/consumer/8972v100.pdf

Its not going to get you near to 2s - you'd need quite a few (maybe 6) in series as their selection guide says one chip is good for up to 330mS.

Thanks for your reply!
Yes delay is very less 320msec!

Hope someone will come with required circuit.
