tools for frequency domain analysis of audio.

Project description

about

freaky is a command-line tool converting between audio and image representations of frequency intensity over time.

a spectrogram is a visual representation of the frequency "spectra" of a signal over time. they are useful for a wide range of audio analysis. this tool was created to study the characteristics of PZT crystals as chaotic dynamical systems and their application in reservoir computing.

this frequency-domain decomposition is somewhat intuitive given that humans percieve sound in the frequency-intensity domain [1].

usage

to convert a .WAV file into a frequency-domain, image representation, run encode.py:

$ freaky-encode example.wav spectrogram.bmp

to convert a .BMP image into a reconstructed .WAV file, run decode.py:

$ freaky-decode spectrogram.bmp reconstructed.wav

further command line parameters can be found by passing the --help flag to either python program.
