Hi, I'm looking for a method to deal with the rising edge of a fast-rising sine wave (or wave peaks that are ahead of phase compared to the original signal, waveform image attached). Analog processing circuits are preferred but I'd also be grateful if someone recommends a DSP algorithm
Sorry for bad english, but i am wanting a distortion circuit that makes the rising edge of the sine wave in the audio rise faster than the original signal
I can only suggest a line of thought:
1) Divide the blue waveform by the green one (as close to zero as you can), to get the exact transfer characteristic (Vout vs Vin) of the required distortion.
2) Find circuitry that can implement the said distortion to the required amount of accuracy.

You can also amplify the sine wave and limit the amplitude so it turns into a sort of square wave, which will make the edges more steep, if that is what you want.

Simply wire an inductor of suitable value to your output > connected to 680ohms to ground and your solution is done.
PS.
What is the frequency of your waveform PICTURE ???

Sine wave can be turned into square, with gain and clipping circuit.
Far as I remember getting the " shark fin " type rising edge is a treble boost
There is numerous slope generators in analog synthesis.
Either rising or falling edges
Depends what you are trying to do. For rising edge as a trigger? envelope?
Unusually you turn the sine into square and then a rising slope can be a " attack" envelope
of falling edge a " release" envelope
By using a rising or falling slope generator, usually slew limiter aka, high pass or low pass
Problem is the frequency needs to be known for the slew limiter.
For any frequency to be a envelope trigger. would have to do my homework, been awhile.
