audioviz

Audioviz is a simple and easy to use library that helps you visualise raw audio-data

This is done with the help of the Fast Fourier Transform algorithm, some frequency-space and volume normalisation and optional effects like gravity.

Features

  • Fast Fourier transform via RustFFT with space and volume normalisation
  • high-level abstraction but still possible to do everything manually
  • multiple interpolation modes like cubic and linear
  • system audio capturing using cpal
  • should be possible to implement in any project
  • modular design

Rust features
