I guess this question is mostly for Victor,
in the string models you posted several months ago, the sr = kr, ksmps =1 which is kind of processor heavy. the table reading and writing seemed to be at a rate, was the only reason for the high k rate the excitation signal? or am I ignoring something A -- Send bugs reports to [hidden email] (or to http://www.cs.bath.ac.uk/cgi-bin/csound ) To unsubscribe, send email to [hidden email] |
I'm using an allpass filter that has 1-sample feedback delays, so
the only way of doing that is kr=sr. However, the best way of doing it currently is putting the code in a UDO, which can have a local kr.

i thought that the krate only affected k rate variables?
since the allpass filters were redefining variables on the next line of code, wouldn't that happen at a rate? or if not, could the delay1 opcode be used instead?

the delay1 opcode could be used, and the other filter-design
opcodes. But I forgot to add that the feedback delay in the waveguide needs kr=sr. Kr affects everything. It is in effect a by-product of the fact that we are calculating sound in blocks of ksmps. Think of the instr code as having an implicit loop that at every pass updates k and a-rate variables. The k-rate ones are single values, scalars, whereas a-rate are whole blocks of ksmps samples. So if you want to have 1-sample delays you need to set ksmps=1. For the filters I can use delay1, but the waveguide implementation needs the 1-sample delay.

Hello to all after a long time off the net and this list.
I lost my hard drive a while back, and I need to download the UDOs on the csounds site again. I sent DR. B an email, but he has not responded. When I go to download the UDO file from the csounds site I get an access forbiden violation. When I try to log on nothing happens. Using internet explorer latest. ver 6 sp 1 TIA, Michael Rempel -- Send bugs reports to [hidden email] (or to http://www.cs.bath.ac.uk/cgi-bin/csound ) To unsubscribe, send email to [hidden email] |
Hi Michael,
I think I got it fixed now. Sorry about that! Please try again and let me know if there's any problems. (Directory was not set as executable, which I guess was necessary.) steven On 5/10/05, Michael Rempel <[hidden email]> wrote: > Hello to all after a long time off the net and this list. > > I lost my hard drive a while back, and I need to download the UDOs on the > csounds site again. > > I sent DR.
