PyAudio录制/捕获和停止/终止Python中的Raspi

Question

我不是Python的专家，尝试通过USB音频设备捕捉/记录音频。 它在指挥终端上运行良好。 但我想制作一个程序，只录制音频，并在我想要的时候停止。在

我听说ab8pyaudio库有特定的API来执行这个工作（比如pyaudio.pyaudio(), pyaudio.pyaudio.open(), 音频.pystream, pyaudio.stream.close, pyaudio.pyaudio.terminate.终止()..... 在

有人能帮忙用Python编写一个简单的录音程序吗？ 谢谢您。在

Answer 1

我只是在命令前面加上相关的注释，让我知道如果你想清除更多的ab8吗

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()
