python声音采集

以下是使用Python进行声音采集的示例代码：

import pyaudio
import wave

# 设置录音参数
CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 44100
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "output.wav"

# 初始化PyAudio
audio = pyaudio.PyAudio()

# 打开音频流
stream = audio.open(format=FORMAT, channels=CHANNELS,
                    rate=RATE, input=True,
                    frames_per_buffer=CHUNK)

print("开始录音......")

# 录音缓存
frames = []

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

print("录音结束！")

# 关闭音频流
stream.stop_stream()
stream.close()
audio.terminate()

# 写入录音文件
with wave.open(WAVE_OUTPUT_FILENAME, 'wb') as wf:
    wf.setnchannels(CHANNELS)
    wf.setsampwidth(audio.get_sample_size(FORMAT))
    wf.setframerate(RATE)
    wf.writeframes(b''.join(frames))

print("录音文件已保存：", WAVE_OUTPUT_FILENAME)

这段代码使用PyAudio库进行声音采集，将采集到的音频数据写入WAV文件中。你可以根据自己的需求修改参数，例如录音时长、采样率等。
