I am using an array to display the waveform of signal as it goes to the [dac~].

When I change between different wave shapes (using a simple oscilator) however, the whole bunch of data will randomly jump up or down. I am fairly sure that the new data sets its zero on wherever the last data left off if that helps.

I was just wondering if there was some way to reset the array so that the middle of the waveform is always in the middle of the array.

Thanks.

I am using the version

Pd-0.43.4 ("extended")

@Shlappas Without seeing your patch....... hard to know, but I doubt that the waveform is offset by the tail of the previous one. It is more likely that you have some real dc component and so you could try a [hip~] before the scope. If that doesn't do the trick then please post back....... and the patch would then be useful!.......

Ok, so I did a bit of looking through my patches and I think the culprit is the delay method I'm using. I also tried to mess around with changing the phase of the oscilators so that when they are on 0Hz they dont have any amplitude but I'm not sure how successful that was.

Here is the Delay patch:
Delay.pd

And the Audio-Out patch I am using:
Audio-Out.pd

And for good measure the Oscilator:
Oscilator.pd

Thanks!

@Shlappas Hello again......
Correcting the phases solves your oscillator problem, including for the square wave at 0hz and zero pulse width. But if you increase the pulse width for the square wave generator at 0Hz the base line is correctly shifted to centre the power, and so then (and only then) you will have an unavoidable dc offset (I think)......

This one modifies your square wave generator and (maybe) works better.......
setting the level to "zero" at "zero" frequency...... but maintaining a symmetrical (about zero) pulse width adjustable square wave.

Awesome! Thank you very much David.

@Shlappas You are very welcome.... I hope it does what you wish....
