If you want to shift the pitch of audio data without affecting the duration, you might have already discovered that it's quite non-trivial, but the PSOLA algorithm is here to help. This project offers a small suite of python functions to provide an API for developers to use the PSOLA algorithm in Python!
This project consists of the following Python modules:
-
psola.py: The PSOLA (Pitch Synchronous Overlap Add) technique, which is a widely used method in speech synthesis and pitch modification. -
pitch_detection.py: This module currently only contains the auto correlate method to determine pitches
- Python 3.x
- NumPy: The only external library used in this project, essential for its array manipulation and numerical operations capabilities.
Import the modules as needed in your Python scripts to utilize their functions for audio analysis and processing tasks.
Example:
from your_project_name import psola, pitch_detectionContributions to this project are welcome. Please ensure that your code adheres to the existing style and that all new functionalities are properly documented.
