免费在线 AU 转 MP2 转换器

AU is a file extension for a sound file format belonging to Sun, NeXT and DEC and used in UNIX. The AU file format is also known as the Sparc-audio or u-law fomat. AU files contain three parts: the audio data and text for a header (containing 24 bytes) and an annotation block.

MP2 is a lossy audio compression format developed by MPEG (Moving Picture Experts Group). It is widely used for audio broadcasting, while MP3 is more common for desktop and online programs. The format is supported only by some audio players, so you may need to convert it to a more popular one like MP3.
