electronics_shamim Posted May 1, 2007 Report Share Posted May 1, 2007 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==== Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted May 1, 2007 Report Share Posted May 1, 2007 I found this http://www.web-ee.com/Electronic-Projects/projects/digital_echo/index.htmhttp://documentation.renesas.com/eng/products/assp/rej03f0170_m65845afpds.pdfhttp://documentation.renesas.com/eng/products/assp/rej03f0085_m65856sp.pdf Quote Link to comment Share on other sites More sharing options...
electronics_shamim Posted May 2, 2007 Author Report Share Posted May 2, 2007 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.==== Quote Link to comment Share on other sites More sharing options...
MP Posted June 9, 2007 Report Share Posted June 9, 2007 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.http://www.elecdesign.com/Articles/Index.cfm?AD=1&ArticleID=8056MP Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted June 9, 2007 Report Share Posted June 9, 2007 You could just buy a karaoke and use the circuit in it. Quote Link to comment Share on other sites More sharing options...
