That true!

A similar uestion has been answered recently on this same mailing list while
talking about flanger ( which in fact is a modulated delay line ).
Without more info and possibly a block diagram or a code snippet there is
little we can do to help you.

Hi,
Thanks for your replies.
What I hear is definitely related with the modulation. The artefacts are
audible every time the modulation is applied: manually or automatically (please
not that I have an interpolator for manual parameter changes to avoid

If I use interpolation for buffer access I experience less glitch and more

What type of interpolation are you using? I would think you need
something better than linear interpolation for this. I'd try
Hi,
I’m trying to implement a modulated delay line which will be used on a chorus
effect.
I think the problem that I will refer to is already well know and please
forgive me my ignorance if that’s the case.
When I modulate the delay time, I experience some glitch/alias which is not
pleasant.
In case it helps, it isn't the delay buffer size that you need to
modify, but rather just your read index into that delay buffer.
If you have a flange for instance that can go from 0 to 500ms in the
past, and is controlled by a sine wave, you always have a 500ms buffer
that you put your output
Alan,
I don’t change the size. I change the read index. I have posted my delay read
function in my previous email.

Two things:
readIndex() only checks to see if the index is 0 but y1 y2 have positive
offsets applied so they will index past the end of the buffer. Also, is the
modulation both positive and negative? If so, it could run off the start of
the buffer.

Steven Cook.

With most IRs, you don’t see discrete peaks, it’s a continuous signal. This is
due to the response of the speaker and microphone being used. This causes some

sure, so let's say we deconvolve that smear because we think it's a lot
