Description

Build Status Coverage Status ReadTheDocs Status PyPI

Yodel (the Swiss Army knife for your sound) is an easy-to-use Python package for digital audio signal processing, analysis and synthesis. It is meant to provide a comprehensive set of tools to manipulate audio signals. It can be used for prototyping as well as developing audio applications in Python.

Features

  • Analysis:
    • Discrete Fourier Transform
    • Fast Fourier Transform
    • Windowing: Hamming, Hanning, Blackman
  • Filtering:
    • Single Pole: low-pass, high-pass
    • Biquad: low-pass, high-pass, band-pass, all-pass, notch, peak, low-shelf, high-shelf
    • State Variable: low-pass, high-pass, band-pass, band-reject
    • Parametric Equalizer
    • Comb: feedforward, feedback, all-pass
    • Convolution: standard, fast
    • Windowed Sinc: low-pass, high-pass, band-pass, band-reject
    • Custom
  • Delay:
    • Time-varying delayline

Installation

Simply run: pip install yodel
