sndfile-spectrogram1

Generate a spectrogram from an input sound file

Usage

sndfile-spectrogram [options] <sound file> <img width> <img height> <png name>

Overview

sndfile-spectrogram reads a single channel sound file and generates a spectrogram which is written to a PNG file with specified image height and width.

The optional parameters allow the user to specify the dynamic range of the spectrogram plot and/or to disable the drawing of borders, scales, heat map and title. Run "sndfile-spectrogram --help" for more information.

The input file is read using libsndfile (http://www.mega-nerd.com/libsndfile/), the spectrogram is calculated with the help of libfftw and the spectrogram is rendered and written to the output file using libcairo.
