AU 音频

AU 是一种主要用于存储音频数据的文件格式。AU 格式常见于 Unix 系统，支持各种编码方法，包括 PCM、µ-law 和 A-law。它通常用于简单的音频录制，并以其相对简单性以及与特定硬件和软件平台的兼容性而闻名。它支持多种音频属性，例如采样率和通道数，从而允许音频质量的灵活性。

M4A音频文件

M4A 是一种音频格式，通常用于存储音乐、有声读物和播客。它使用高级音频编码 (AAC) 或 Apple 无损音频编解码器 (ALAC) 来压缩音频数据。 M4A 文件以相对较小的文件大小提供良好的音质，使其成为数字分发和流媒体的理想选择。 它在各种平台和设备上得到广泛支持，确保了音频录音的回放兼容性。

AU to M4A Conversion: Everything You Need to Know

Need to convert an AU audio file to the more widely compatible M4A format? This page explains the benefits of converting AU to M4A and provides a free and easy online conversion tool.

What is an AU File?

AU is a simple audio file format originally used by Sun Microsystems. It's often found on Unix systems and is sometimes used for simple audio recordings or as an interchange format. However, it's not as universally supported as other audio formats.

What is an M4A File?

M4A (MPEG-4 Audio) is a widely used audio format that offers excellent audio quality with relatively small file sizes. It's the standard audio format for Apple devices and is supported by a wide range of media players and devices. It often uses the Advanced Audio Coding (AAC) codec for efficient compression.

Why Convert AU to M4A?

Converting from AU to M4A provides several advantages:

  • Improved Compatibility: M4A is supported by virtually all modern media players and devices, unlike AU.
  • Smaller File Size: M4A files typically have a smaller file size than AU files, especially when using the AAC codec, saving storage space and bandwidth.
  • Better Audio Quality: AAC, the codec commonly used with M4A, offers better audio quality at the same bitrate compared to older codecs sometimes used with AU.
  • Easier Sharing: The widespread compatibility of M4A makes it much easier to share your audio files with others.
