Thanks guys!

[zexy/z~] looks exactly like what I'm looking for!

you can just use [delwrite~] + [delread~], but you have to make sure that they are scheduled in the right order, see "G05.execution.order.pd" in "doc/3.audio.examples". Also, you have to convert from samples to milliseconds.

For convenience, I often use [z~] from zexy, which is a delay line in a single object, with the delay time given in samples.

Hi everybody!

I'm planning on delaying a bandpass filter by samples to create a comb filter effect. Is this possible or can it be done only by audio blocks?

If it is possible which object(s) would I use?

Thanks Ingo

I also needed a delay in samples and so I made an abstraction in Pd vanilla, delaying a signal with x number of  samples; for example a one sample delay is [delaysam 1] I think this is the correct way of doing this without needing externals... Hans

but this can also be done in vanilla like people said (though somewhat inconvenient)

Thanks Hans and IOhannes!

I'll take a look at this as well but so far [zexy/z~] looks best to me.

kind of.

• using [$1] can give you all kinds of nasty surprises, as you can e.g.

use [delaysam samplerate~]. i'd rather go for [float $1] instead.

• debugging printout (and a fan-out!) should be removed
• why do you use [vd~]? do you need fractional sample-delay (the answer

might well be "yes")? if not, than [vd~] is just taking more CPU-power...

• why do you ramp to the target-delay with [line~]? since you cannot change

the delay after the instantiation, i would rather have it jump to the target delay immediately.

gfasdrm, IOhannes

[vd~] has sub-sample accuracy, using 4-point interpolation, just like [tabread4~]. Actually, the new name of the object is [delread4~] ;-)

I have built a comb filter (actually a flanger) using a combo of [delwrite~ foo] and a series of [vd~ foo]s using an LFO which is phase-displaced across the different [vd~]s.

Can anyone tell me what is the best resolution I can get with this combo? It it less than a per-sample resolution?

Can I build this system using something other than [vd~] to get better resolution?

Thanks. BH
