Hi, Guys!
Excelent job on Pitch Shifter in VLC 3.0.x.

Is there any form of http control implemented for this feature, once the filter has been activated?
I'm implementing a web based karaoke player and pitch control would be highly valuable!

Something like
http://127.0.0.1:8080/requests/status.x ... ch&val=800
http://127.0.0.1:8080/requests/status.x ... ch&val=800
or
http://127.0.0.1:8080/requests/status.x ... ft&val=800
Thanks!

Noone has coded that, I'm afraid.

I'd like to second that this would be an amazing feature.

Karaoke is a totally overlooked usage of VLC, and it is SO close to being a perfect player for this function.

The web interface would certainly be nice, but RC interface already provides a perfect template for it. An ideal karaoke machine would simply play a video fullscreen and allow you to, remotely, without interrupting the video's display, shift pitch, change speed, and add items to the playlist. VLC's RC is SO SO close on this. Is there really no possibility for slightly extending the RC functionality given that it would open up an entire new use case for users?

Yes, anybody could write this, but it's probably not a priority unfortunately.

I would like to see this feature too.

me too.
Looking into it further:
+ pitch (without changing tempo/speed) would be nice (percentage and halftones)
+ speed/tempo (without changing pitch)
i found that the current speed control changes the pitch so i cant use it - therefore an activex control does not help

I second this opinion on the value that pitch and speed control would add to an already strong player. From Karaoke to music applications, it seems that more users need these features. In this time of the pandemic, we want to create and expand what we can do. End users are also looking for more capable apps. Maybe someone will get motivated and add these key components to VLC.

The Pitch and Speed controls are already there...Just that the controls are not easily accessible. The request is to have a web interface so that user can adjust pitch and/or speed remotely without disturbing the video.

Turns out that this feature is already available...just not right out of the box. To be able to adjust pitch, speed, or any other settings...just modify the httprequests.lua file and add whatever function you need. See the following link for reference.
