pyaudio录制多声道

import pyaudio
import numpy as np

# 设置参数
channels = 2  # 声道数
sample_rate = 44100  # 采样率
chunk_size = 1024  # 每次读取的音频帧数

# 创建音频流对象
p = pyaudio.PyAudio()
stream = p.open(format=pyaudio.paInt16,
                channels=channels,
                rate=sample_rate,
                input=True,
                frames_per_buffer=chunk_size)

# 录制音频
frames = []
for i in range(0, int(sample_rate / chunk_size * 5)):  # 录制5秒钟的音频
    data = stream.read(chunk_size)
    frames.append(np.frombuffer(data, dtype=np.int16))

# 停止录制
stream.stop_stream()
stream.close()
p.terminate()

# 处理录制的音频数据
audio_data = np.vstack(frames)  # 将多个声道的数据垂直堆叠在一起
left_channel = audio_data[:, 0]  # 左声道数据
right_channel = audio_data[:, 1]  # 右声道数据

# 进一步处理音频数据...
