AC3音频

AC3是由杜比实验室开发的一种音频格式，以其提供多声道环绕声的能力而闻名。它通常用于家庭影院系统、DVD和数字影院。AC3提供良好的音频质量和高效的压缩，使其适用于分发数字音频内容。它最多支持5.1声道，提供身临其境的聆听体验。通常在视频文件中使用，以提供增强的音频效果。

AAC音频

AAC（高级音频编码）是一种音频编码标准，以其高效的压缩和高质量的声音而闻名。 它广泛用于数字音频压缩，并且在流式传输、下载和存储音乐和其他音频内容方面很受欢迎。 与MP3相比，AAC在较低的比特率下提供更高的音频保真度，使其成为带宽受限环境的理想选择。 受到各种设备和操作系统的支持，确保为寻求最佳音频体验的用户提供广泛的兼容性。
