What are the steps to convert an AU file to SDSF on LetsConvert?

What is the advantage of converting AU to SDSF?

AU files are commonly used in Unix-based applications, but many legacy DAWs and audio editors recognize SDSF more readily. SDSF also supports more comprehensive metadata and can yield smaller file sizes without sacrificing audio data, making it easier to archive and share recordings.

How does LetsConvert handle sample rate and channel data when converting AU to SDSF?

The converter preserves the original sample rate, bit depth, and channel count from the AU file. If the AU file contains µ-law compressed audio, it is expanded to linear PCM to fit the SDSF container, ensuring no additional loss. However, auxiliary metadata such as markers or cue points may not be transferred if the SDSF format does not support them.
