使用 pyaudio 的录音无法按预期工作
voice recording using pyaudio not working as expected
这是我编写的用于录制音频的代码,直到我停止程序并将其保存在 output.wav 中。问题是 output.wav 都是无声的,当我打印帧时,它们都是零。我是 运行 它在 Mac OS 上。我尝试使用 Mac 录音机录制音频并且它可以正常工作,所以我想麦克风应该没有问题。为什么会这样?
有什么建议吗?
import pyaudio
import wave
CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 2
RATE = 44100
def record():
p = pyaudio.PyAudio()
stream = p.open(format=FORMAT,
channels=CHANNELS,
rate=RATE,
input=True,
frames_per_buffer=CHUNK)
print("Start recording")
frames = []
try:
while True:
data = stream.read(CHUNK)
frames.append(data)
except KeyboardInterrupt:
print("Done recording")
except Exception as e:
print(str(e))
sample_width = p.get_sample_size(FORMAT)
stream.stop_stream()
stream.close()
p.terminate()
return sample_width, frames
def record_to_file(file_path):
wf = wave.open(file_path, 'wb')
wf.setnchannels(CHANNELS)
sample_width, frames = record()
wf.setsampwidth(sample_width)
wf.setframerate(RATE)
wf.writeframes(b''.join(frames))
wf.close()
if __name__ == '__main__':
print('#' * 80)
print("Please speak word(s) into the microphone")
print('Press Ctrl+C to stop the recording')
record_to_file('output.wav')
print("Result written to output.wav")
print('#' * 80)
运行 我的 Windows 10 machine 和 python 3.7 上的这段代码生成了一个音频文件。确保 mac
上的麦克风 enabled
