SNDFILE-SPECTROGRAM(1)

💖 SNDFILE-SPECTROGRAM 💖

okay bestie, this one's from the General Commands Manual section and it's genuinely iconic, let me put you on 💅

✨ NAME ✨

sndfile-spectrogram — generate a spectrogram from an input sound file 🎀

🌈 SYNOPSIS 🌈

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

🦋 DESCRIPTION 🦋

so basically sndfile-spectrogram reads a single channel sound file and generates a spectrogram, which gets written out to a PNG file with the image height and width you asked for. main character behaviour honestly 👑

the optional parameters let you specify the dynamic range of the spectrogram plot and/or disable the drawing of borders, scales, heat map and title. that's a lot of vibes you can toggle off, fr fr. run this if you want more deets:

sndfile-spectrogram --help

the input file is read using libsndfile (http://www.mega-nerd.com/libsndfile/), the spectrogram is calculated with the help of libfftw, and then the spectrogram is rendered and written to the output file using libcairo. it's giving teamwork, it's giving pipeline, we love a collab 💖

ngl the way this tool stacks three whole libraries just to make one pretty picture? that's a glow up 🧚✨
