How do I convert AU to LA step by step?

Upload your AU file, select LA as the output format, and click Convert. Our tool decodes the Sun/NeXT PCM or mu-law audio and encodes it using the LA lossless codec. After the process finishes, download the resulting .la file. No software installation is required.

Why should I convert AU to LA instead of keeping AU?

AU files are common on legacy Unix/Sun workstations but use limited compression. LA is a modern lossless codec that reduces file size by 30–50% while preserving every bit of audio data. Converting to LA saves storage and bandwidth, making it ideal for archiving high-fidelity audio or sharing over networks.

What audio attributes are preserved during AU to LA conversion?

Our converter preserves the original sample rate (e.g., 44.1 kHz), bit depth (e.g., 16/24-bit), and channel configuration (mono/stereo/multichannel) during encoding. LA lossless compression stores exact PCM samples, so no audio information is lost; existing metadata like tags is normalized to LA's native metadata tags.

Is AU-TO-LA free to use?
