how to design a echo effect use sigmadsp?
Hello , everybody, i want use echo effect,
so , i'm use delay module, but it max delay times is only ≈8000samples， it's about 170ms !
how can i add some extra time to use ?
because ad144x and sigmadsp cannot add extra ram memory...
any one have some good idea?
thanks for your help.
If you need a longer delay you might need to step up to SigmaStudio for Sharc. Although I haven't used it personally it seems like it should have more resources available for this type of processing.
Hi Walkercc:
Do you need the full audio bandwidth 44kHz? If not, you could possibly interpolate your delay.
Please comment.

Miguel,
Below is a working example of an interpolated delay reverb based on jon71's wonderful idea for a "synchronous mux." It provides double the normal delay at half the BW. As shown it runs on a -1701 eval board. Of course, with the -144x a much longer delay is possible.
