Im looking for way to delay an audio signal for more than 30 seconds. I know how to do this with the help of my computer but i cant seem to find another way, a way where i dont need my computer.



I've found a way by using Pure Data + Raspberry Pi + USB Sound card :)

  • That's actually not a bad suggestion :D Cheap as well. Requires a display and mouse+keyboard to setup though. – Internet Human Feb 11 '13 at 15:49

look into broadcast delay units from the radio world like this one http://www.sonifex.co.uk/redbox/rbpd2_ld.shtml


Most digital crossovers for speakers have the ability to delay. XTA makes many different kinds.
