[Cs-dev] CSound flush the delay line

Hi, it's me again with the delay. I settled on a deltapi solution for my
implementation.
Currently when I change the delaytime in real time I hear a bit of clicks,
which is repeated again and again by the delay.
I would like to flush out the whatever is in the delay line whenever I
change the delaytime so that I don't get this.
I've tried multiplying aout, ain, kfdbk by 0 but it doesn't help the
situation.
Is there a simple way to clear out the delay buffer?
Many thanks for your help.
Here's my instrument
instr 101
klastDelTimeL init 0
kdelayOn chnget "delayOn"
kfdbkL chnget "feedbackL"
kdeltimeL chnget "delaytimeL"
kamp chnget "delaydepth"
kChanged changed kdeltimeL
ain = gaDelayBus
gaDelayBus = 0
;iamp = p4
kParam = 1
if (kdelayOn==1) then
;simple delay
aout delayr 6.0
aout1 deltapi kdeltimeL
if (kChanged==1) then
kParam = 0
endif
delayw ain + (aout1 * kfdbkL * kParam)
aoutL = aout1 * kamp
outs aoutL, aoutL
if (kdelayOn==0) then
outs ain * 0, ain * 0
endif
endin

I don't think there is a simple way to flush the delayline (I think it would need a loop of some sort). Did you try smoothing the delaytime controls with a lowpass filter like port? That might help remove the clicks. Victor On 18 Jun 2013, at 07:00, lppier wrote: > Hi, it's me again with the delay.

Hi Victor, How would I do that? Could you show me a rough example? Many thanks.. Did you try smoothing the delaytime controls with a lowpass filter like port? That might help remove the clicks.

kdel port kdeltimeL, 0.01 ...then use kdel in deltapi. On 18 Jun 2013, at 08:30, lppier wrote:

| Thanks, tried it but it I still hear the clicks/distortion. It is an interesting opcode though! Pier. On 18 Jun, 2013, at 3:40 PM, Victor Lazzarini <Victor.Lazzarini@nuim.ie> wrote:
