Python 波浪读框堆叠在下面。移动范围

嗨，我有阅读大波文件的问题。 代码良好，但范围会导致堆栈溢出

handle = wave.open('data_sylaby\s1.wav', 'r')
framerate = handle.getframerate();
nframes = handle.getnframes()

for i in range(handle.getnframes()):
        frame = handle.readframes(1)
        data = struct.unpack("<h", frame)

---

data=pack（'thx我需要修复解包并用xrange替换range
    handle = wave.open('data_sylaby\s1.wav', 'r')
    framerate = handle.getframerate();
    nframes = handle.getnframes()
    i = 0
    while i  < nframes:
        frame = handle.readframes(1)
        data = struct.unpack("<h", frame)
        i = i + 1

for j in range(nframes/framerate + 1):
        for i in range(j *framerate, (j+1)*framerate):
            if i >= nframes:
                break
