A quick way to generate spectrograms for a bunch of audio files

generate sox spectrograms.sh

### Generate PNG spectrograms using SoX
### Use the input file name as the title within the image as well as the output file name
### Set the width to 2000 (seems to output a ~2140px wide image)

### Generate for FLAC
for file in *.flac;do
	outfile="${file%.*}.png"
	title_in_pic="${file%.*}"
	sox "$file" -n spectrogram -t "$title_in_pic" -o "$outfile" -x 2000
done

### Generate for MP3
for file in *.mp3;do
	outfile="${file%.*}.png"
	title_in_pic="${file%.*}"
	sox "$file" -n spectrogram -t "$title_in_pic" -o "$outfile" -x 2000
done

### Generate for Ogg Vorbis
for file in *.ogg;do
	outfile="${file%.*}.png"
	title_in_pic="${file%.*}"
	sox "$file" -n spectrogram -t "$title_in_pic" -o "$outfile" -x 2000
done
