我正在尝试使用下面显示的以下函数来清理和缩减音频采样。我陷入了这个我缺乏理解的错误。有人愿意解释一下并希望帮助我解决这个问题吗？
我可以看到它与 wavio 功能有关，并且无法读取文件。
代码如下：
def envelope(y, rate, threshold):
mask = []
y = pd.Series(y).apply(np.abs)
y_mean = y.rolling(window=int(rate/20),
min_periods=1,
center=True).max()
for mean in y_mean:
if mean > threshold:
mask.append(True)
else:
mask.append(False)
return mask, y_mean
def downsample_mono(path, sr):
obj = wavio.read(path)
wav = obj.data.astype(np.float32, order='F')
rate = obj.rate
try:
tmp = wav.shape[1]
wav = to_mono(wav.T)
except:
pass
wav = resample(wav, rate, sr)
wav = wav.astype(np.int16)
return sr, wav
def save_sample(sample, rate, target_dir, fn, ix):
fn = fn.split('.wav')[0]
dst_path = os.path.join(target_dir.split('.')[0], fn+'_{}.wav'.format(str(ix))) …
