So I am new to PureData and have been trying to create a simple tone generator, (sine, saw, square), It seems that no matter what I do every time I try to connect any of my waves that use phasor creates a crackling noise or clipping, That is even added to my sine wave giving it like a strong vibrato. I have tried separating each of these waves but it still continues to happen, even when the volume is lowered it still has that crackling sound, I also noticed that it causes my graph to jump up and down even when at rest. Any tips?

I cannot seem to be able to send the project folder as it does not appear on my computer? Any help with that?

@JackCrescent Your waves are all full volume, you mix three of them together and you get distortion. Disconnect the wire going to the right inlet of each of the [*~] and make them [*~ 0.25] This will lower the volume and keep your output from clipping. Having the waveform go to both inlets of the [*~] just makes it do frequency multiplication.

this should help some.

That seems to have stopped them from sort of meshing and having that issue, now there is just a slight crackling, but it has greatly diminished, thank you very much!

Is it intentional that you're squaring the waveforms?

@ddw_music near the end not really, but since I am new to pureData I am a bit confused as to how to completely separate them.

at the end they merge a little which would be fine, but my main issue is this:

sometimes my graphs jump up or down, but slightly, but at some intervals it releases sounds creating that crackling or like motor exhaust sound, it has been reduced for now, but its still a bit there.

@JackCrescent Not sure about finding the project folder. Try doing a "saveas" from the pd menu. The OS tree box that pops up should show you where Pd is trying to save the patch..... hopefully the same place as it was last saved to.

The graphs will jump if the [metro] is not in sync with the [osc~]..... difficult to achieve especially with incoming midi notes (you could reset the phase of [osc~] as the metro bangs but that will cause clicks in the output of [osc~]......
And if you are reading from the arrays they need to be a complete waveform so that the first level in the graph is the same as the last.
Otherwise the signal jumps as the reader wraps back to the beginning.... which causes a click (they will probably sound like a buzz..... or "motor exhaust sound" as they arrive so rapidly).

That means the length of the array (the number of points) needs to be correct for a complete waveform.
It should be a better idea to construct the waveforms only once....... and then read them at different speeds (adjusted for the midi note) using [phasor~] connected to [tabread~] or better still [tabread4~].

There is a very good guide here...... http://write.flossmanuals.net/pure-data/generating-waveforms/ that uses [tabread4~] for interpolation...
It also shows (but doesn't explain unfortunately) the maths necessary for the interpolation (in fact the length of the array... 2051... is 2048 samples.... a good multiple of 64 that contains enough data points for a fairly smooth wave..... plus 3 for the interpolation as [tabread4~] is reading 4 samples at a time and "smoothing" the samples even when the [phasor~] is wrapping around the end of the array).
And it shows how the playback speed is controlled by midi note input.

You should look at the help files for the objects (right-click them for "help") [osc~] [phasor~] and [tabread4~] and then google the terms you don't understand.
Pd itself is quite easy to understand but digital audio requires some basic knowledge or it looks like fairy dust.......
