exponent-mod-help.pd
this is a part of a patch that i use to modify any sound to make it sound different. I will release that when it's finished.
I want to have this part of the patch to be audio signal only, to make it more flexible for audio-modifying.
i believe something can be done with patches like expr~, but i don't properly know how to deal with those, because i'm a newbie in Pure Data.
Any help is appreciated: Any explenation of ideas on how to do it, and any patch which adds to this, though please do both.

I love this community!

@4ZZ4 This will do for the top inlet..... or the left inlet...... exponent-mod~.pd
At this moment I cannot get my head around the two inlets.
At control rate the values are one or the other.
At signal rate they are both at once.
It depends what you are doing with the answer and only you can know........ whether you will add/subtract/multiply/divide them.....
David.

@whale-av i will check your patch after i send this patch:
exponent-wave.pd
i obviously should have sent the whole patch, sorry about that, and thank you for helping me!

@4ZZ4 Here is [unsig~] for proof of concept...... unsig~.pd
David.

@whale-av what does the $1 variable doing in the unsig~ patch?

@whale-av
what does [sig~ -1] do here?

@4ZZ4 You can change the metro rate for the [snapshot~]...... to sample the signal more (or less) often by giving it an argument........ [unsig~ 500] for example.
It is an abstraction...... so then $1 becomes 500 and replaces the 300 that is the default set in the metro if no argument is given.

[pow~ -1] for some reason did not give the correct output.
Setting the -1 with an external [sig~ -1] forced it to work.
Not sure why, but it might require a signal rate signal on the right inlet to work at all.
David.

@whale-av regarding the [sig~ -1] thing. does there exist something that could work as a [t f b], but it's for audio signal instead?

@whale-av also, why do you ask if i should multiply/divide/add/subtract something?

@whale-av I do have everything that i need for my original post here in your first post here, so thank you, you helped me very much, man!

i still don't know what you mean by which operator that i should put in the middle.

i'm going to integrate the parts that you added to my main patch, now, and later show my result.

@whale-av exponent-wave-2.pd

@4ZZ4 [t f b] sends a bang and then the float every time a float is received.
But an audio signal is arriving constantly..... 44100ish times a second, so no.
[bang~] will send a bang (control bang) every 64 samples....... and can send a bang every sample if it is in a subpatch with a [block 1] in it as well.
You might be wanting to send a float at a given signal value in which case [threshold~]

But what are you trying to achieve?

I ask about multiply etc. because in your original control rate patch you have [t f f]
Either the result of the top half is sent on, or the float from the left inlet.
But with signals they are both arriving at the same time and it cannot be one or the other.
How do you decide which one?

If you only occasionally have signals arriving at each inlet..... and at different times I suppose you could automatically switch between them.
If the top part goes to zero you could test for that and kill the input to where the trigger is, and then use [+~] in place of the trigger.

Audio is not at all the same as control signals. Although it is still numbers it is a constant stream of them.
I suppose it would be possible to interleave the samples (switching between the top and side inputs)....... but at what rate? And the output will be a mess.
So the question is...... what do you want the final output to represent..... what is the relationship between the two inputs and how should they be combined?
David.

@4ZZ4 Usually inlets of audio objects add the signals together....... and that should be true for the right inlet of [pow~] in "exponent-wave-2.pd"
So you are adding the signals and have the sum of the two signals as the power.
David.

@whale-av i just want to clarify, these two inlets will never be used at the same time, therefore, i won't add them.

i'm confused about what you write, and i do not know how to ask a proper question to this, so if you want to, you could {insert word for retelling something with different linguistic/grammatical structure}. thanks.

@whale-av could you create a new version of this: , with only taking into account this part: i want it to be audio-only as last time.

@4ZZ4 You just need to connect [inlet~ 2nd] to the second [expr~] as well.
Like this....
David.

@whale-av i did that but it does not do the work when the input is above 0, unlinke the one without audio signal that i created. here's a comparison: tester_file.pd exponent-wave-2.pd exponent-wave.pd

you can just download them into one empty folder, and then delete them afterwards.

@4ZZ4 It is as I thought. The two audio rate calcs combined will not work.
I have added a switch to switch off the unused inlet (softly ..... no clicks).
Also..... sorry..... I compacted your patch as I am working on a small screen.
Try this....... exponent-wave-2.pd
It looks and sounds correct to me.
David.

@whale-av Thanks, you've helped me very much. i refined the switch to only needing one toggle, because it does not need to play both at the same time: exponent-wave-3.pd.
