# Python-pitch-shifting-RT

A python algorithm to change the pitch of the voice in real time. It is also possible to control the pitch shifting rate in real time in the command line interface.

## Requirements

- pyaudio

- readchar

## Installation

``` shell

git clone https://github.com/pprablanc/ppsrt.git

cd ppsrt

pip install -e .

```

## Usage

In the terminal:

``` shell

cd ppsrt

./ppsrt.py

```

In the terminal interface, you can increase/decrease the pitch shift of the voice with '+'/'-' keys respectively.

To leave the program, hit space twice.

## Warnings

If you use this program within Spyder IDE, you might have problems with readchar. It is recommended to use it in a standard terminal.
