Any simulation apps where you can load jpg schematics?

Are there any apps where you can load jpg schematics for the AI to analyze it and let you simulate it and test it, for example allowing you to send a signal into the modelled pedal described on a schematic to test it at different points like you do with an audio probe?

I doubt there are any programs that can recognize a schematic from a jpg picture and simulate it.

Schematic files normally consist of model symbols connected together with wires on a (often hidden) grid with X-Y coordinates.

There are some tools, such as SINA, that attempt to extract simulation netlists from a photo image of a schematic. They work best on well drawn, high-contrast schematics that are very clean with very little additional annotation. Even so, they generally require quite a bit of manual tweaking of the result to correct errors. You would then need to add the various simulation controls that your simulator supports in order to make the result interactable.

This is one of many active research areas in the AI field and, like most of them, it is still in its infancy. As a result, don't expect there to be wondrous capabilities for some time yet, but do expect rapid progress over the next several years.

If it's not complicated, then it will probably be a lot easier and faster to just enter it into a suitable schematic for your simulator manually and move on.
Also on my list as an option. But which are the editors that allow probing the signal? Are there any like that, so I can test how the audio passing through sounds at different points?

hi son,
Using the LTSpice simulator it is possible to use audio wav files to play and record the input and sample point sounds and then play them back as audio.

Do you have a circuit to post, so that we can see the project?
