===========================================
waveform python module. Synopsis:
import waveform
# quickly draw the waveform of an mp3 file to a picture
waveform.draw("infile.mp3", "outfile.png", (800, 100), bgColor=(0,0,0,0),
fgColor=(0,0,128,255))
# draw using a gradient
center_color = (184, 221, 242, 255)
outer_color = (19, 117, 205, 255)
waveform.draw("infile.mp3", "outfile.png", (800, 100), bgColor=(0,0,0,0),
fgGradientCenter=center_color, fgGradientOuter=outer_color)
# generate the picture extremely quickly at the loss of how
# good the image looks
waveform.draw("infile.mp3", "outfile.png", (800, 100), cheat=True)
Supported audio formats:
