Hi, VD~ und delread~ are both processing Data / delayed sound from delwrite~ what is similar and what are differences between VD~ und delread~ ?

i guess you are referring to [vd~] (i don't know of an uppercase object of that name).

from the documentation (vd~-help.pd):

vd~ implements a 4-point interpolating delay tap from a corresponding delwrite~ object. The delay in milliseconds of the tap is specified by the incoming signal.

as with [delread~], you can change the delay time only with a number (message), and not with a signal.

this basically means, that with [vd~] you can change the delay continuously, whereas with [delread~] you cannot: [delread~]s delay time will only be updated at block boundaries (each 64 samples))

it also means, that with [vd~] you can have delays of fractional samples, whereas with [delread~] the actual delay time is always an integer sample value.

so [vd~] is obviously "better". but then, it also takes more CPU power, so if you don't care for continuously changing the delay or never needed fractional sample delays, you are probably better off using [delread~].
