我想停止键盘输入处的音频录制,并希望将其录制为wav文件。 如您所知,我正在运行刻录机一个小时。基本上,我想在在线面试中分析候选人记录的回答。我的要求是稍微更改代码,以便我可以在特定的键盘输入处停止并检索记录。请告诉我该怎么做(可能的代码说明)。
import pyaudio
import wave
CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 2
RATE = 44100
RECORD_SECONDS = 3600
WAVE_OUTPUT_FILENAME = "voice.wav"
p = pyaudio.PyAudio()
stream = p.open(format=FORMAT,
channels=CHANNELS,
rate=RATE,
input=True,
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()
stream.close()
p.terminate()
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()
