The _stftPitchShiftPlugin_ features poly pitch and timbre shifting simultaneously and in real-time.

It's completely based on the [stftPitchShift](https://github.com/jurihock/stftPitchShift) library,

which also provides a Python interface and useful command line tools.



## Features



Following features are currently included:



- poly pitch shifting with or without formant preservation,

- pitch independent timbre changing,

- low latency capability depending on the preset block size,

- optional output normalization to match the input loudness level.



The _stftPitchShiftPlugin_ is available in VST3, AU, LV2 formats as well as a standalone app.

It also provides a basic UI to adjust the effect parameters on the fly:






Please refer to the [User Manual](MANUAL.md) for detailed explanations.



## Binaries



The ready to use binaries can be obtained in two ways:



- via continuous build artifacts or

- via a local build from the source code.



### Continuous build artifacts



Use one of the following links to download the latest binaries for your specific operating system:



- [macOS](https://nightly.link/jurihock/stftPitchShiftPlugin/workflows/build/main/StftPitchShiftPlugin-macos-latest.zip)

- [Ubuntu](https://nightly.link/jurihock/stftPitchShiftPlugin/workflows/build/main/StftPitchShiftPlugin-ubuntu-latest.zip)

- [Windows](https://nightly.link/jurihock/stftPitchShiftPlugin/workflows/build/main/StftPitchShiftPlugin-windows-latest.zip)



On macOS, you will also have to deal with the [Gatekeeper](https://support.apple.com/HT202491),

in order to execute the standalone app or to load the AU or VST3 plugin in your DAW.



### Build from source code



Since the project is based on _CMake_, it can be compiled in the same way on any of the supported operating systems.



Please read the official JUCE [documentation](https://github.com/juce-framework/JUCE/blob/master/docs/CMake%20API.md) and the included script files:



- [build_macos.sh](scripts/build_macos.sh)

- [build_ubuntu.sh](scripts/build_ubuntu.sh)

- [build_windows.bat](scripts/build_windows.bat)



The advantage of this method on macOS is that no additional _Gatekeeper_ handling is required.



## Last but not least



This project is currently at an early development stage, so expect more highlights to come.



Stay tuned!
