Question

我不是Python的专家，试图通过USB音频设备捕获/录制音频。它在命令终端上工作正常。但我想制作一个只录制音频的节目，并在我想要的时候停止播放。

我听说ab8 Pyaudio库有一定的API来执行这项工作（如pyaudio.PyAudio（），pyaudio.Pyaudio.open（），pyaudio.stream，pyaudio.stream.close，pyaudio.PyAudio.terminate（）。 ....

有人可以帮助制作一个简单的Python录音程序吗？谢谢。

我只是在命令面前添加相关评论，让我知道如果你想清除更多ab8它

import pyaudio, wave, sys

CHUNK = 8192
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 44100
RECORD_SECONDS = 10


WAVE_OUTPUT_FILENAME = 'Audio_.wav'
p = pyaudio.PyAudio()

stream = p.open(format=FORMAT,
               channels = CHANNELS,
               rate = RATE,
               input = True,
               input_device_index = 0,
               frames_per_buffer = CHUNK)

print("* recording")

frames = []

for i in range(0, int(RATE / CHUNK * RECORD_SECONDS)):
    data = stream.read(CHUNK)
    frames.append(data)

print("* done recording")

stream.stop_stream()    # "Stop Audio Recording
stream.close()          # "Close Audio Recording
p.terminate()           # "Audio System Close

wf = wave.open(WAVE_OUTPUT_FILENAME, 'wb')
wf.setnchannels(CHANNELS)
wf.setsampwidth(p.get_sample_size(FORMAT))
wf.setframerate(RATE)
wf.writeframes(b''.join(frames))
wf.close()

PyAudio在Raspi上用Python录制/捕获和停止/终止
