Audio Pitch Manipulating Envelope

Dear Community, I am struggling to find a way to manipulate an audio signal with slight pitch changes over time. I would like to have some sort of envelope with time points, where the pitch modulation can be entered. Any help is much appreciated! Thanks!

did you see/try this? https://stackoverflow.com/questions/44698489/incrementally-gradually-change-pitch-of-signal-over-time-using-octave-matlab

alternatively there is an matlab example of real time pitch shifting, it shuld be possible to get code an offlien version if it

Hey Jonas, thanks for the links. I was searching extensively but have not seen them before. Maybe it is possible to achieve it this way but I was hoping for a simpler, still more flexible solution. Adobe Audition for example has some sort of line where you can set points and manipulate the pitch + and - I was hoping for something similar with time points and pitch values. Thank you for your help I will check out your links in detail later!

alternatively you can look for information of the plugin you are speaking of or look of Audacity has the same feature. I think you can look up all of Audacity's algorithms and rebuild it in matlab. I think there is also a way to use audio Plugins in Matlab.
