用JAVA从wav文件中提取振幅阵列

            // 计算每个采样点的振幅数值范围
            double amplitudeRange = Math.pow(2, audioFormat.getSampleSizeInBits()) / 2;

            // 创建一个缓冲区，用于存储振幅阵列
            byte[] buffer = new byte[audioInputStream.available()];

            // 读取音频数据到缓冲区

        } catch (UnsupportedAudioFileException | IOException e) {
