Hello, i’m trying to change the pitch of a playing sound in a blueprint, and while that works neatly on PC, on Android i hear no effect. Is this feature actually supported on mobile? ---

Indeed by looking at the source it does not seem implemented, neither the location and velocity of the source seem to be considered. ---

Is this just not yet in, or is this not possible on mobile, i wonder… ---

According the [OpenSL ES reference](https://www.khronos.org/files/opensl-es-1-1-quick-reference.pdf), there is a SLPitchIt interface. I imagine it’s only a question of time to get it integrated, this implementation is fairly new in UE4. ---

Hi, i just want to push this. Audio pitch does not work on mobile in 4.6.1. for me. Is that my fault or is it still unsupported? ---

I have the same problem, using 4.7.5. This is terrible – pitch is one of the most important cues for audio! (More important than volume.) ---

Just got an e-mail notification because of your answer. Like you, i still have the problem. I don’t want to import unnecessary soundfiles because of this, which are blowing up the app size ☹ ---

Works on iOS, not on Android. You can use free software like Audacity to do it there for a workaround on Android if you’re not experienced or skilled with audio design. ---

The issue is that this workaround implies more assets, and that you can’t do it in realtime. An actual workaround would require a software resampler to be integrated as a custom sound node - which I would be happy to create as soon as the marketplace allows easy code sharing. ---

That answer is intended for those who can’t design that, which is almost everyone, and those who can’t wait for it to be designed for them. That’s baller that you can do that though ---
