Python recording and plotting audio

To record and plot audio with Python, use Python's audio processing library and plotting library.

Here is a simple example code that demonstrates how to record audio and plot its waveform using Python:

import wave
import numpy as np
import matplotlib.pyplot as plt

# 设置音频参数
sample_rate = 44100  # 采样率
duration = 5  # 录制时长（秒）
frequency = 440  # 音频频率（Hz）
volume = 32767
