[Csnd] how to clear/zera a-array

The Csound Mailinglist

Hi!

What is the best way to set all elements of an audio array to 0?

If the array is declared as

gaOutput[] init 10

clear gaOutput
does not work

clear gaOutput[0], gaOutput[1], etc

works but is cumbersome for longer arrays

gaOutput fillarray 0

does not wor with a-arrays.

I am sure there is an elegent way but I cannot find it.

Thanks!

Hello,

this is not elegant but maybe can be wrapped in a udo

kIndx   =       0
while kIndx < lenarray(aArr) do
aArr[kIndx] = 0 
kIndx = kIndx + 1
od

Looks like we need an overload of fillarray for audio variables.

Thanks!

And most logical would be to have zeroing the arrays too.

That’s done now. Tested with

asig[] diskin “fox.wav”
clear asig
