Python音频去噪

要在Python中对音频进行去噪处理，你可以使用scipy库中的wavfile模块、noisereduce库和pyaudio库。首先，你需要导入所需的库并读取音频文件和噪声文件。然后，你可以使用noisereduce库中的reduce_noise函数对音频文件进行去噪处理。接下来，你可以使用pyaudio库创建一个wave文件并将去噪后的音频数据写入该文件中。

以下是一个示例代码：

from scipy.io import wavfile
import noisereduce as nr
import pyaudio
import time
import wave

rate, data = wavfile.read("001.wav")
_, noisy_part = wavfile.read("noise.wav")
SAMPLING_FREQUENCY = 16000
reduced_noise = nr.reduce_noise(y=data, y_noise=noisy_part, sr=SAMPLING_FREQUENCY)

FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 16000
RECORD_SECONDS = time

WAVE_OUTPUT_FILENAME = "out_file.wav"

with wave.open(WAVE_OUTPUT_FILENAME, 'wb') as wf:
    wf.setnchannels(CHANNELS)
    wf.setsampwidth(2)
    wf.setframerate(RATE)
    wf.writeframes(b''.join(reduced_noise))
