You want to use an interpolated delay line structure to do adjustable delays, you create the delay line in the ipass, make it large enough to cover the reasonable range of delays, and then pick the tap on the delay line that matches the current delay you want (or, if you want the smoothest changes in delays, do interpolation). One way to do this is the fracdelay core opcode: http://www.cs.berkeley.edu/~lazzaro/sa/book/opcodes/filter/index.html#frac Although honestly, I wouldn't use it, but instead I would build my own custom delay line opcode, and get a nicer API than the psuedo-OO fracdelay API ... it will also be easier to benchmark and tune the delay line structure to run efficiently, since you'll be able to make micro changes in the SAOL and see the result in the C code in the sa.c file. ------------------------------------------------------------------------- John Lazzaro -- Research Specialist -- CS Division -- EECS -- UC Berkeley lazzaro [at] cs [dot] berkeley [dot] edu www.cs.berkeley.edu/~lazzaro -------------------------------------------------------------------------
