Description

Converts an audio file to a 3D spectrogram; (optionally) saves as a stereolithography (STL) file for 3D printing

Arguments

inputfile (required): filepath string associated with WAV audio file

outputfile (optional): filepath string associated with STL file to save

sampfreq: re-sampling frequency

axisnorm: keep the x- and y-axis scaling (FALSE) or normalize so that they have the same dimensions (TRUE)

preemph: value for pre-emphasis of audio

window: option for windowing audio using a variety of Matlab/Octave compatible filters found in the "signal" package ex: 'bartlett', 'blackman', 'hamming', 'hanning', 'triang'

Requirements

See requirements.txt for packages. Install them with the requiRements R package or by hand.

The author specified no minimum R version but experiments indicate that 3.6.1 is too old. 4.1.1 works like a charm, at least on Windows 10.
