Create Soundcloud style waveform from Audio in Python

waveform.py

from pydub import AudioSegment
from matplotlib import pyplot as plot
from PIL import Image, ImageDraw
import numpy as np
import os

src = "./test.mp3"

audio = AudioSegment.from_file(src)
data = np.fromstring(audio._data, np.int16)
fs = audio.frame_rate

BARS = 100
BAR_HEIGHT = 60
LINE_WIDTH = 5

length = len(data)
RATIO = length/BARS

count = 0
maximum_item = 0
max_array = []
highest_line = 0

for d in data:
	if count < RATIO:
		count = count + 1

		if abs(d) > maximum_item:
			maximum_item = abs(d)
	else:
		max_array.append(maximum_item)

		if maximum_item > highest_line:
			highest_line = maximum_item

		maximum_item = 0
		count = 1

line_ratio = highest_line/BAR_HEIGHT

im = Image.new('RGBA', (BARS * LINE_WIDTH, BAR_HEIGHT), (255, 255, 255, 1))
draw = ImageDraw.Draw(im)

current_x = 1
for item in max_array:
	item_height = item/line_ratio

	current_y = (BAR_HEIGHT - item_height)/2
	draw.line((current_x, current_y, current_x, current_y + item_height), fill=(169, 171, 172), width=4)

	current_x = current_x + LINE_WIDTH

im.show()

Hi, great stuff!
Why did you import matplotlib?
