DrBunsen Posted July 23, 2005 Report Share Posted July 23, 2005 http://oatleyelectronics.com/bcorner2.htmlsm7183DIGITAL ECHO CHIP:Â SM7183 is an audio echo processor using CMOS technology. It has built-in AD / DA and 30KBits SRAM for time delay. Features direct control & micro-processor control interface, adjustable delay time setting: Echo mode 20.5ms ~ 163.8ms, Surround mode: 4.1ms ~ 41ms. Click here for data sheet. $6Admittedly it's a short delay time, but perhaps a few of them could be strung together - multitap? Quote Link to comment Share on other sites More sharing options...
moebius Posted July 25, 2005 Report Share Posted July 25, 2005 Hi,You can probably abuse it's "oscillator resistor" pin6 as Scott Bernandi has done with PT2399 echo to get longer (and more distorted) delays ;) http://home.comcast.net/~sbernardi/elec/og2/og3_echo.htmlBye, Moebius Quote Link to comment Share on other sites More sharing options...
AndrewMartens Posted July 25, 2005 Report Share Posted July 25, 2005 Ahhh, the PT2399. I hate to admit it, but I think those are still available for purchase at Small Bear Electronics. I really need to get some of those chips sometime... Quote Link to comment Share on other sites More sharing options...
