2024年Python最全使用Python实现音频双通道分离，2024年最新阿里p7面试难度

sample_rate, wav_data = wavfile.read(wav_path)
left = []
right = []
for item in wav_data:
left.append(item[0])
right.append(item[1])
wavfile.write(left_wav_path, sample_rate, np.array(left))
wavfile.write(right_wav_path, sample_rate, np.array(right))
except IOError as e:
print(‘error is %s’ % str(e))
except:
print(‘other error’, sys.exc_info())
if name == ‘main’:
mp3_to_wav(‘input/test.mp3’, ‘tmp/tmp.wav’)
split_channel(‘tmp/tmp.wav’, ‘output/left.wav’, ‘output/right.wav’)
其中调用了一个自定义的库，converter.py 加入了代码：
‘’’

‘’’
from pydub import AudioSegment
def mp3_to_wav(source, destin):
“”"
mp3 转 wav
:param source:
:param destin:
:return None:
“”"
data = AudioSegment.from_mp3(source)
data.export(destin, format=‘wav’)
