How do I convert a CVSL file to AU audio?

Upload your CVSL file to LetsConvert, select AU as the output format from the dropdown (choose PCM, u-law, or A-law codec if prompted), then click 'Convert'. Once processed, download the resulting .au file. For multiple files, use the batch mode to convert entire folders of CVSL files to AU in one go.

Why would I need to convert CVSL to AU instead of keeping the original format?

CVSL files are often used in proprietary telephony or dictation systems and may not be playable in standard media players. Converting to Sun AU ensures compatibility with Unix/Linux audio tools, audio editors, and web browsers that handle .au natively. It also allows you to archive recordings in an open, uncompressed format without licensing restrictions.

Will converting CVSL to AU preserve the original audio quality and metadata?

The converter remaps the CVSL audio stream into AU containers without re-encoding if the source codec matches the target settings, preserving sample rate, bit depth, and channel count. However, metadata like file-specific CVSL headers and compression flags (e.g., dictation timestamps) are not part of the AU specification, so that data is not carried over. For lossless conversion, choose the 'uncompressed PCM' AU variant.

Is there any software installation required?
