MP2 to AU Audio conversion is the process of transforming audio data encoded in the MPEG-1 Layer II (MP2) format into the AU audio file format used by Sun/NeXT systems and many audio tools. This conversion rewraps or re-encodes the audio so it can be played or processed by software and devices that prefer or require the AU container and its typical PCM or µ-law encodings.

MP2 files typically use the audio/mpeg MIME type and are encoded with MPEG-1 or MPEG-2 Layer II codecs. AU audio files commonly use the audio/basic or audio/au MIME types and support PCM or μ-law codecs. MP2 is widely used in broadcasting, whereas AU is favored in legacy Unix systems and audio editing applications.
The AU Audio (.AU) format is commonly used for audio. Understanding its characteristics can be helpful when converting to or from other formats like MP2.
While specific technical details aren't available here, AU Audio files generally serve the purpose of storing audio effectively within their domain.
Our online MP2 to AU converter allows you to transform your MP2 audio files into AU format in just a few simple steps. Designed for ease of use and fast processing, this tool is perfect for users who need to convert audio files without installing software. Whether for professional or personal use, converting MP2 to AU audio has never been more accessible.
MP2 is a compressed audio format commonly used for broadcasting and digital radio, offering efficient compression with decent quality. AU audio is an older audio file format favored in Unix and Sun Microsystems systems, often used for professional audio editing and playback. While MP2 focuses on compression efficiency, AU provides simpler structure and broad support in legacy environments.
Keep original MP2 sample rate (e.g., 44.1 kHz) when converting to AU to avoid unnecessary resampling and preserve audio fidelity.
For best quality, export AU as 16-bit or 24-bit PCM rather than µ-law/A-law; choose PCM if the target application supports larger files.
If you have many files, use batch conversion with consistent sample rate and bit depth settings to maintain uniform results and save time.
Limit individual file size under ~250 MB for free online converters to avoid upload/timeout issues; split very large recordings before converting.

Note format limitation: AU is often associated with PCM or µ-law; converting MP2 (a lossy codec) to AU PCM will not restore lost detail—it only changes container/codec.
