解释wav文件中的原始数据

import wave

# 打开WAV文件
with wave.open('audio.wav', 'rb') as wav_file:
    # 获取参数
    params = wav_file.getparams()
    num_channels = params.nchannels
    sample_width = params.sampwidth
    sample_rate = params.framerate
    num_frames = params.nframes

    # 读取原始数据
    raw_data = wav_file.readframes(num_frames)

import javax.sound.sampled.*;

// 打开WAV文件
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File("audio.wav"));

// 获取参数
AudioFormat format = audioInputStream.getFormat();
int num_channels = format.getChannels();
int sample_size = format.getSampleSizeInBits();
float sample_rate = format.getSampleRate();
int num_frames = (int) audioInputStream.getFrameLength();

// 读取原始数据
byte[] raw_data = new byte[num_frames * num_channels * sample_size / 8];
audioInputStream.read(raw_data);
